MidiNoteIn

MIDI Note input module

version 1

monophonic

Notes about polyphony: For polyphic patches use PolyMidiNoteIn instead.

This is a MIDI note input module.

The ch selector sets the MIDI channel to listen to. OMNI means that it listens to all MIDI channels, and ch 1 - 16 are the usual MIDI channels.

When a note on is seen the gate output will go on and the note number will be put on the 'note' output. The velocity will go to the 'velocity on' output.

When a subsequent note off is seen for the currently active note the gate will turn off, and the note off velocity will be set on the 'velocity off' output.

Note on messages with a velocity of zero are treated as note offs (with a note off velocity of zero).

When the channel is changed the current note will be turned off (with zero note off velocity), and the same will happen when a MIDI all notes off command (CC 123 with value 0) is seen or when the 'Panic' function is used (Action menu / Panic or ctrl+P).

MidiMultiNoteIn

MIDI 4 Note input module

version 1

monophonic

Notes about polyphony: For polyphic patches use PolyMidiNoteIn instead.

This is a MIDI four note input module.

This module is superceded by the Midi8NoteIn module which uses the same internal coded with the additionl flexibility of setting a limit to the actual amount of notes to handle. For this module the channel count is four and that is fixed.

The ch selector sets the MIDI channel to listen to, OMNI means that it listens to all MIDI channels, and ch 1 - 16 are the usual MIDI channels.

When a note on is seen the gate output will go on and the note number will be put on the 'note' output. The velocity will go to the 'velocity on' output. When a subsequent note in arrives it will be routed to the 2nd output set, etc.

When a subsequent note off is seen for the currently active note the gate will turn off, and the note off velocity will be set on the 'velocity off' output.

Note on messages with a velocity of zero are treated as note offs (with a note offf velocity of zero).

When the channel is changed the current notes will be turned off (with zero note off velocity), and the same will happen when a MIDI all notes off command (CC 123 with value 0) is seen or when the Panic function is used (menu Action / Panic, or ctrl + P).

The 'note stealing' mode comes in effect when there are four active notes and a new one comes in, the different modes act like:

  • none : no note stealing - find first free, if none free, skip the new note.

  • cyclic : round robin, just use the next note slot regardless of how long it was on.

  • softest : replace the softest note. This needs the level input, connect this to an envelope for instance. When no such note was found this mode acts like the cyclic mode.

  • oldest : replace oldest note, this will replace the note that was active for the longest time, when no such note was found this mode acts like the cyclic mode.

  • lowest : replace lowest note, the note with the lowest note number is replaced, when no such note was found this mode acts like the cyclic mode.

  • highest : replace highest note, the note with the highest note number is replaced, when no such note was found this mode acts like the cyclic mode.

  • newest : replace newest note, the note that was turned on last will be replaced, when no such note was found this mode acts like the cyclic mode.

This module handles incoming pitch bend messages and after touch.

Midi8NoteIn

MIDI 8 Note input module

version 1

monophonic

Notes about polyphony: For polyphic patches use PolyMidiNoteIn instead.

This is a MIDI multi note input module with one to eight channels.

This module supercedes the MidiMultNoteIn module, which uses exaclly the same internal code with the flexibility of setting a limit to the maximum of notes to be used.

The max. notes selector sets the amount of channels to be used.

The ch selector sets the MIDI channel to listen to, OMNI means that it listens to all MIDI channels, and ch 1 - 16 are the usual MIDI channels.

When a note on is seen the gate output will go on and the note number will be put on the 'note' output. The velocity will go to the 'velocity on' output. When a subsequent note in arrives it will be routed to the 2nd output set, etc.

When a subsequent note off is seen for the currently active note the gate will turn off, and the note off velocity will be set on the 'velocity off' output.

7 MidiCCIn

Page: I/O [type 1302]

MidiCCIn

MIDI CC input module

version 1

monophonic

This is a MIDI CC input module.

The ch selector and the cc selector set the CC event to listen for. When ch = OMNI it will match all MIDI channels, values 1 - 16 to the corresponding MIDI channels.

When a new CC event is detected the gate input will go on for a short time, and the value will be put on the value output. The value did not necessarily change when the gate input becomes active, it reacts to a matching incoming CC message.

The incoming value range [0,127] is mapped to an output range [0,1].

8 MidiClockIn

Page: I/O [type 1313]

MidiClockIn

MIDI clock in

version 1

polyphonic

Notes about polyphony: P and X ins are poly.

A MIDI clock input module.

The control output can be used some different kind of controls. It can either control an LFO which is set to fast 0.254, medium 2:05 or to BPM; a Delay set to 3s or 5 min, or it can control the ClockGen module's BPM value.

The sync output is activated for 1 ms on each detected beat (4/4 is assumed always), it can be used to sync an LFO (when the rate multiplier is set to a / mode (less than 1) an extra divider will be needed to not prematurely reset the LFO).

The rate multiplier controls determine the scaling applied to the control output, it will make controlled LFOs go faster or slower by some factor.

The master (rsm or m) output can be used to control a chain of RateConverter (or Tapper) modules, this module will then be the master controlling all other modules in the chain. Other rate converters (or tappers) can be set to different control modes to get LFOs and delays synced up properly at different rates.

The rsmm output is a scaled master output, it scales with the detected BPM and the set rate, all slaves will follow this one whilst the master output scales with the detected BPM rate only, the m output is determined by the detected BPM rate only.

The active output will initially be on, it will go off after a MIDI stop message was received, after a start or a continue message it will go on again.

The P and X modulation inputs are polyphonic, the active, the m, and the sync output are monophonic and the rsm and control outputs are polyphonic (controlled by P and X).

9 MidiNoteOut

Page: I/O [type 1303]

MidiNoteOut

MIDI Note output module

version 1

polyphonic

This is a MIDI note output module.

The ch selector sets the MIDI channel to send to, where ch 1 - 16 are the usual MIDI channels and ic 1 to 16 are internal MIDI channels (MIDI receivers in a patch can just use ch 1 - 16 (or OMNI) to connect to these).

The note input determines what note value will be sent, the velocity inputs determine the on or off velocity to use.

Each time when the gate input changes from inactive to active a note on event is sent with the currently set note on velocity.

Each time when the gate goes from active to inactive a note off event is sent for the note that that was previously turned on, and this event will be sent to the same MIDI channel that the note on had been sent out (even when the set MIDI channels changed in the mean time). For this event the current note off velocity will be used. When no note on event had been sent there will not be a note off event either.

When the note value changes no note event will be sent, only changes on the gate input can cause a note event to be generated (*).

When the channel is changed no note event will be sent out, only changes on the gate input can cause a note event to be generated (*).

(*) This will not result in hanging notes as when the gate goes inactive the channel and note number for the active note will be used to base the note off on.

10 MidiCCOut

Page: I/O [type 1304]

MidiCCOut

MIDI CC output module

version 1

polyphonic

Notes about polyphony: This module listens on all voices.

This is a MIDI CC output module.

The ch selector and the cc selector define the CC event to be transmitted, ch 1 - ch 16 to the correspond to to the usual MIDI channels, ic 1 - ic 16 to the internal MIDI channels (MIDI receivers in a patch can just use ch 1 - 16 (or OMNI) to connect to these). All normal CC values 0 - 119 can be sent and additionally the special values 120 - 127 can be used as well.

When the gate input goes from inactive to active the event will be sent out using the current value as present on the value input.

When the ch, cc or value change there will not be a new MIDI event generated - MIDI events occur only when the gate goes from inactive to active.

The sent output will go active after the MIDI message was sent, this can be used to trigger a chain of events to happen in a specified order.

MidiPCOut

MIDI Program Change output module

version 1

monophonic

Notes about polyphony: This module listens to the first voice only.

This is a MIDI Program Change output module.

The ch selector and the prg selector define the program change event to be transmitted, ch 1 - ch 16 to the correspond to to the usual MIDI channels, ic 1 - ic 16 to the internal MIDI channels (MIDI receivers in a patch can just use ch 1 - 16 (or OMNI) to connect to these).

When the gate input goes from inactive to active the event will be sent out using the SUM of the current values as set by the prg control and read from the progr. input.

When the ch or the progr input change there will not be a new MIDI event generated - MIDI events occur only when the gate goes from inactive to active, or when the prg control is changed manually.

The sent output will go active after the MIDI message was sent, this can be used to trigger a chain of events to happen in a specified order.

MidiPNOut

MIDI RPN and NRPN output module

version 1

monophonic

Notes about polyphony: This module listens to the first voice only.

This is a MIDI RPN and NRPN output module.

It can send one (mode M) or two septets (mode B) of data.

In RPN mode it will send param h to CC 101 and param l to CC 100 and then it will send the most significant value septet to CC 6. When the mode is B it will then additionally send the least significant data septet on CC 38.

In NRPN mode it will send param h to CC 99 and param l to CC 98 and then it will send the most significant value septet to CC 6. When the mode is B it will then additionally send the least significant data septet on CC 38.

he value input has a zero to one range, and it is scaled up to the full pussible ange before transmission.

version 1

monophonic

[this module is RateSmart [1]]

A MIDI SysEx output module.

NOTE: this module is not working yet.

A sequence of numbers and parameters can be filled in from which a MIDI SysEx message will be computed.

The parameters are the eight inputs which can be used as %1 .. %8.

On the rising edge of the gate input the parameters will be read in and will be filled into the message which will then be sent out over MIDI.

NOTE: this module is not working yet.

14 Sync

Page: I/O [type 1306]

Sync

Sync Wren instances

version 1

polyphonic

Notes about polyphony: the 'sync in' input listens on the first voice only, 'sync out' sends to all voices.

Sync Wren instances over OSC

When Wren is set to be an OSC receiver this module will receive OSC /sync messages.

When Wren is set to be an OSC transmitter this module will send OSC /sync messages.

When a sync message is received the sync output will go active just long enough to reliably trigger a control rate logic input.

When the sync in input goes from low to high the OSC /sync message is sent and also the sync output will be activated in the same manner as when an OSC /sync message was received.

There can only be one working sync receiver in a patch, when there are more an arbitrary one will service incoming /sync messages. There can be multiple working sync senders though (in a Wren instance that was set to be an OSC transmitter).

The sync message has one float parameter, it can, for isnstance, be used to synce tuning over different Wren instances.

15 OscMessage

Page: I/O [type 1307]

OscMessage

Send or receive OSC

version 1

polyphonic

Notes about polyphony: The 'send' inputs listen on the first voice only, the 'recv' output sends to all voices.

Send or receive OSC messages.

This module can both send and receive OSC messages, depending on the role chosen for this Wren instance.

For an OSC transmitter it will send the value present on the blue (send) input when the green input goes from low to high to the address present in the address box. In this case the value will also be copied to the output (so this doubles as a slow rate sample and hold).

For an OSC receiver it will listen to OSC type f messages on the address specified in the address box and it will send the value found in the message to the output. Note that when you you clock in input values as well the output value may toggle between the OSC received value and the clocked in value.

To set an address control click the address field to pop up a text editor, and when done use ctrl+enter to save the edit. In the address the leading slash (/) character must not be specified, Wrenn will add it by itself.

Each address can be used only once, when it occurs multiple times an arbitrary instance of the module will handle it and the other instances will think it to be handled already after that. There can be multiple senders on the same address for a Wren instance that is set to be an OSC transmitter though.

Messages may be sent to Wren with more than one parameter, however only the first parameter will be used and only when it's type is 'f' (float).

Note: OSC address strings are case sensitive, so 'module' does not match 'Module'.

Note: All Wren modules can receive OSC messages when their name starts with an @ character.

Recorder

Wave recorder

version 1

monophonic

Notes about polyphony: This module sums all voices before processing them, the 'clear', 'write' and 'record' inputs listen to first voice only, the 'rec off', 'rec on' and 'full' outputs send to all voices equally.

Recorder

A 1 to 8 channel audo recorder that can write it's recording to a wave file on disk.

The tape length can be set from 1 to 30 minutes and when the tape is full recording will continue writing over old material.

The record control starts or stops recording, the write control starts a disk write (for which a file has to be selected before) and the clear control will erase the tape.

Write, clear and record can be controlled by the buttons as well as by logic input signals.

The rec on ouput is active when recording is on.

The rec of output is active when recording is OFF, such that when it is connected to the clear and write inputs the wave gets saved and cleared when recording is stopped.

The full output goes active when the tape loop is fully recorded, such that when connected to the clear and write inputs the wave gets saved when the loop is full.

In the file name %patchname% can be used, this will be replaced by the name of the patch. When you patch is C:\wren\patches\silly-putty.wren the patch name will be silly-putty, and the wave data will be written to C:\wren\recordings\cc-silly-putty.wav.

When 'time stamped' is being selected the file name will be prefixed by a time stamp.

When 'normalized' is selected the wave data will be normalized before it is being written out to the file.

When the file name is clear, the box will show 'Ctrl click to select a file' in that case data will not be written to disk at all, there will be no prompt for a file to save to.

The am input controls the output volume, at audio rates. When not connected the assumed value is 1.

The shape morph input allows for morphing between the four basic oscillator shapes (it is the input directly left of the shape selector). The morph input signal is being multiplied by four and then added to the wave selector control value. From this two waves are selected ( sine, tri), ( tri, saw), (saw, square) or (square, sine) and a mix from those two will be sent to the output, proportionally to the morph input value. It is the red input left of the wave selector.

Percussion Oscillator

This one is modelled loosely after the pch2csd implementation of the Clavia G2 OscPerc modue (type 195 there).

As an extra a speed input was added, which unconnected holds a value of 0.5. When Speed is 0 the oscillator runs not, it may still click tho. And when speed is 1.0 the oscillator runs twice the speed of the set value.

There is a small quirk, when the decay time is set long for the trig repetition rate the module starts to click even when click is zero.

The punch effect reshapes the envelope a bit, this does not do the same thing as the Clavia module does.

A PADSynth like module bused on ideas from Nasca Octavian Paul, see: http://zynaddsubfx.sourceforge.net/doc/PADsynth/PADsynth.htm for more on this.

This module use IFFT to generate sound from a spectrum as drawn by the faders and influenced further by the other controls.

The bw / bw-scale controls manipulate the width of the spectral peaks.

The spread and spread type controls manipulate the distance between the peaks.

The module works by generating an in-memory waveform from the spectrum. This wave can then be played at different rates by using the position, speed and frequency controls.

Some of the controls will be clicky as as the IFFT must be recalculated when their positions change.

The module provides its stereo output by using two different tap points on the generated wave.

Wave player

version 1

A wave player module

This module can read a wav file from disk into memory. The wav format needs to be 16 bit, 44.1 kHz - stereo and mono are both fine. The maximum file size is not limited by the module, but as the wave has to be read into memory for very large files you may run out of memory resulting in things to get very slow. Recordings with a length of several minutes should not be a problem.

The speed input controls how fast the wave will be played, and the wave will be played backwards for negative values (or stand still when the speed is zero). When the FM input is connected too the speed will be multiplied by the FM amount (and speed must not be zero).

The position input determines which sample will be sent to the output. This can be used with a sawtooth LFO to play the wave.

The speed input can be thought of as a linear FM control while the position input can be seen a sa linear PM control.

When a stereo wave is loaded the mono stereo switch will convert the selected wave to mono when set as mono, for a mono wave the left and right outputs will always be the same.

Control click the filename field to pop up a file open dialog.

The FM input provides exponential speed control, for it to work the speed input must be set to something unequal to zero - which can be done by having the on-off control as on, or by connecting something unequal to zero to the speed input.

Wave playing is started from the trigger input, as determined by a window set from trigger level to trigger level plus trigger range. Whenever the trigger input moves into that window a trigger condition is seen and whenever it moves out of that window the trigger condition is removed.

Depending on the trigger mode selected:

  • normal: Audio playing will start when a trigger condition occurs, and the full wave will be played then. When the loop mode is set to once the trigger input will then have to first move out of the trigger window before a new trigger can occur. When the loop mode is set to loop wave can start anew without first having to go outside the trigger window.
  • retrig: Wave playing can be restarted before it was fully played, which for fast retriggers will lead to granular like effects (except that no fade out is being performed).

This is an audo rate lookup module, basically. The input value moves a cursor over the horizontal axis and the looked up graph height is then sent to the output. The input wants a positive only signal, the output is bipolar.

Points can be added by double clicking (or with ctrl+click) in an empty area. The same action on an existing point will allow that point to be moved or removed - removing being a move to somewhere out of the graph area.

The leftmost and rightmost points can not be removed, but can only be moved up or down.

This module is better suiatable for audio rates than the DataGraph module, it uses Differential Parabolic Waves internally to suppress the aliasing somewhat.

A right click on the graph area will popup a context menu allowing for some standard wave forms to be created, basic symmetry operations and save to and load from file.

The Phasor module was made to control this module.

the graph on this module uses auto-looping (first and last point will be set to the same Y value) and can optionally use auto-scaling (the full Y range will always be used).

The rnd input, when going from false to true, will set new random Y values for all the points in the graph. The amount of randome being applied is the momentary analog value of the rnd input.

The FM input provides exponential frequency control.

The PWM input provides linear Pulse Width Modulation.

When the trig input changes from zero or less than zero to a value above zero a preset amount of half waves will be sent to to the output. This can be used for VOSIM like synthesis or as an envelope control.

The mute button sets the output to zero when active.

The rdy output becomes active when the module is ready for a new trigger signal.

The output type selector sets the output to either:

  • Full range
  • Full range - inverted signal
  • Positive only
  • Positive only - inverted signal
  • Negative only
  • Negative only - inverted signal

The speed input provides linear trough zero FM. When the input level is 1 the LFO will run twice as fast as it normally would, when zero the LFO will stop, and on negative speeds it will run backwards.

ClockGen

clock generator

version 1

monophonic

A clock generator module.

Tempo can be set from 0 to 255 BPM.

The * 96 green output sends 96 pulses per whole note.

The * 16 green output sends 16 pulses per whole note, swing is applied to this output.

The sync rate can be set to n times a whole note time with the sync div control. The sync output can be used to reset sequencers, for instance.

Swing can be set from 1/2 to 31/32

The blue 96 and 16 ouputs output the internal phase accumulators, so they provide a positive only sawtooth. These can for instance be used to implement your own swing function by feeding them into a comparator.

With the active button the clock can be started and stopped, each time it is started it will be reset internally.

External reset is possible withthe res input.

External tempo control is possible with the tempo input, this overrides the knob setting. You can use a tap control module (set to the right range) for this.

The speed input provides linear trough zero FM. When the input level is 1 the LFO will run twice as fast as it normally would, when zero the LFO will stop, and on negative speeds it will run backwards.

The temo (tempoex) input supports the special NOT_CONNECTED status.

65 ClockGen2

Page: LFO [type 418]

ClockGen2

DataGraph clock generator

version 1

polyphonic

[this module is RateSmart [1]]

ClockGen2, a Clock generator.

This module was especially made for the DataGraph module, the two can make a versatile sequencer together.

The bars control sets the number of bars to be used, that is the number of time divisions to be made in the DataGraph module (which got an input to control its horizontal divisions).

Bars/m or bars per minute sets the play rate for the bars - or the number of divisions per minute to be played in the DataGrap. This sets the module's cycle rate and it is output through the sin, tri, saw and sq(uare) outputs.

The saw output is always affected by the phase controls, the sin, tri and sq ouputs can be switched on or off for this effect (with the samll button below the outputs). The signal type to be used is set for all four with the same control.

Quantization is a rate multiplied version of of the cycle, it is meant to be connected to the DataGraph's quant input and it determines the quantization times to be used - or the note granularity to be used. This is a square wave output and it can have swing (as set by the swing controls) applied to it.

Accents is a rate divided down version of the quantize signal, it can be used to apply accents - it is not involved with the DataGraph module.

There is an overall speed control input for dynamically changing the speed.

The res input provides for a means to sync the module to other signals.

And the active input switches the module between active and inactive, it is xor-ed with the ON / off button. When the module goes from inactive to active it will be reset as well.

There are modulation inputs for Phase, Swing, Bars/m, quantization and accents - all are multiplicative and are 1.0 when not connected.

72 LpGate

Page: Env [type 918]

LpGate

freq

version 1

polyphonic

LpGate, a low-pass gate of sorts.

This is modeled loosely after the Buchla LPG, but it differs a bit.

Internally an AR envelope is used to control two 6dB low pass filters (as a loose approximation of the vactrol response), the filters are detuned a bit to get a bit more than 6dB / octave and a bit less than 12dB / octave.

There is a feedback path from the filter output back to the input, the amount is controlled by the reso knob and modulation. This can spice-up the signal a bit when opened.

The AR times can be changed with the time controls, there is a fixed relation between A and R times.

The filter's base frequency can be set with the freq controls.

The AR triggers when the control signal goes from less than zero to zero or more, in the attack phase the speed of it's signal is proportional to the actual input level. Soft triggering will open the filter less. The release time will not be affected by that. This differs from the Buchla LPG, also a combined mode only is implemented where both level and filter are being controlled from the envelope.

Whenever the module's AR is in the attack phase the control light will turn on.

The AR implementation differs a bit from the one used in the AR type envelope modules as hold will be active always and on a negative going control signal the module will go to the A phase always.

The output signal runs trough a tanh function, as a soft clipper for excessive volumes.

Also there is a DC blocker at the output to get rif of the almost DC values when the gate closes.

73 EnvControl

Page: Env [type 908]

EnvControl

Envellope controller

version 1

polyphonic

A retriggerable envelope controller.

The envelope will start when the trig input goes from zero, or below zero, to above zero. The output will then in the set Attack time go to the level set with the level control. When the trig input falls off the output will start getting larger again for the set Release time, till a value of 1 is reached.

At every new trig start the ouput value is reset to 0, and the above cycle will restart.

Both the Attack and Decay phase are linear.

This module is meant to control the GraphControl module, the actual envelope shape is then drawn in that module. The set level will then correspond to the vertical distance in the graph where the hold value will be.

The EOC (End Of Cycle) output goes active when the full envelope period is finished, or when a period never occured. Fed back into the trigger input sustained self oscillation will take place.

74 Envelope

Envelope

Envelope follower

version 1

polyphonic

An envelope follower module.

The peak decay is meant for the Inv(erted) output. The module tries to estimate a maximum envelope level from the normal output, and that value is used as the reference for the inverted output.

inv = ref - env

When peak decay is off the ref level will be the maximum level seen ever, when peak decay is on the maximum level will go down at the peak decay rate until a new maximum was seen, it then will set that as the new ref level.

The module can be set to use RMS mode or peak level mode.

Detector

A detector module, phase, frequency, amplitude

version 1

polyphonic

[this module is RateSmart [1]]

A detector module.

This module detects instantaneous phase, frequency and amplitude of the ingoing signal. This is based on "complexifying" the input using a hilbert transform. The complex signal is then used to determine the phase, frequency and the amplitude.

This in principle only works for sine shaped inputs, but it can do some interesting stuff on more complex signals too.

The phase output can be used to control the phase input of an oscillator and the amplitude likewise can be connected to the AM input of an oscilator, this then will more or recreate the input signal with the oscillator. The frequency output is linear with frequency, it can drive linear frequency inputs (the MasterOsc module can do lin/exp conversions in various ways).

EnvReso

12 dB resonant envelope generator

version 1

polyphonic

A 12 dB resonant envelope generator.

Based on a low frequency 12 dB / Oct State Variable Filter, for the envelope the filter's low pass is being used, it is labeled as env on the module.

The time and time modulation controls (+ and -) set the cutoff frequency (to a very low value) - there are four ranges available for the timing to be used, fast, medium, slow and vfast (for very fast - in envelope time).

The S control adds stretch to the input pulse, it can be + and - modulated by the two inputs eft of it. The stretch time control span is controlled by the range as well.

The Q control sets the amount of resonance. The Q value can be modulated trough both a + and a - input.

This module doubles as a very low frquency filter when the trig input is not connected; in this case the gain input serves as the main input and when the Q is high, transients will be added to the gain signal (and then be present on the env signal).

The env output really is the the filter's low pass signal.

The bp and hp outputs return the filter's band pass and hig hpass functions. Hp used to be named inv, and it would then output 1.0 - env, but changed that. If you need the 1.0 - functionality you'll have to add that extrnally now (which is easier than to extternally add the HP .. and ran out of pixels a bit :¬) ).

The red input is multiplied by the env signal and then sent to the red output - this acts as a built in VCA.

The trig input supports the special NOT_CONNECTED status.

Average

averager / lag / portamento filter

version 1

[this module is RateSmart [1]]

A exponential moving average type of filter.

The knob controls the alpha parameter.

The LP output is calculated as:

  Delta           := Inp  - Outp;
  Outp            := Outp + FAlpha \* Delta;
  FOutputs[ o_lp] := Normalize( Outp );
  FOutputs[ o_hp] := Normalize( Delta);

So when alpha is zero the output value is frozen and when alpha is one the output will follow the input.

The HP output is calculated as IN - LP, so it will be zero when alpha is one and it will follow the input when alpha is zero.

There is a mode selector for how the differentiator output behaves. When set to transparent it will output both positive and negative differences. When set to half wave it will output negative differences as zero, while letting thru positive differences. When set to full wave mode the absolute value of the difference will be output. This can be used for example to trigger something when a signal goes up, or when it changes.

There is a gain control for the integrator gain to be able to make it clip less.

A differentiator.

This module outputs the difference between the previous input sample and the current one.

There is a mode selector for how the differentiator output behaves. When set to transparent it will output both positive and negative differences. When set to half wave it will output negative differences as zero, while letting thru positive differences. When set to full wave mode the absolute value of the difference will be output. This can be used for example to trigger something when a signal goes up, or when it changes.

The sel input is scaled up and added to the mode selector and then the result taken modulo 3 to determine the actual mode to be used.

98 AllPassSimple

Page: Filter1 [type 727]

AllPassSimple

All pass filter

version 1

polyphonic

An all-pass filter.

An all pass filter passes all frequencies with zero attenuation, but it will change the signal phase in a frequency dependent way.

The delay length can be set with with the length parameter. This is in samples, and so the actual time will depend on the current sample rate.

The feedback factor fb is used to trim the frequency at which the the phase shift is halfway. The factor fb can be modulated but the resulting value always has to be in the range [-1,1].

The LEDs indicates internal clipping of the modulation signal, e.g. it is going outside the range [-1,1].

This unit can be used for several purposes. The phase smearing can be used to reduce peak amplitudes for impulse like signals, helping to avoid clipping. When k is being modulated there will be a phase distortion varying with time, resulting in signal warble or in FM like effects for higher modulation rates and longer lengths.

ValueSync

Value synchronizer

version 1

polyphonic

[this module is RateSmart [1]]

A Value Sync module

The module gets triggered by an incoming positive edge on the pulse input, which it will then hold internally along with the value that was present at that time on the value input. When a subsequent positive edge appears on the sync input the Q output will be set active and the captured input value will be passed to the output. Once the pulse got processed the ouput and the internal state are both being cleared when a negative edge is seen on the sync input. The incoming pulse is guaranteed to never get lost.

This modue can be used to sync up a pulse event appearing at a random time to a syncing clock signal while capturing a value that was present at that time and passing it on on a sync only.

This module acts a bit like a sample and hold in that it captures a value on a trigger, but it will delay passing on that value until a sync signal is seen.

PropScaler

Proportional scaler

version 1

polyphonic

[this module is RateSmart [1]]

A proportional scaler.

The scaling factor p and the offset (1-p) are both set with the same control.

When the control is 1 the output value will always be 1, regardless of the input value. When it is set to 0 the output value follows input value. Set to 0.5, for an input signal going from zero to 1 the output would go from 0.5 to 1.

The formula used is : out = in * ( 1 - p) + p

The value of p can be modulated between zero and 1 trough the modulation input and the modulation amount control.

Effectively this sets a lower limit for the output signal, and the input range is distributed proportionally over the remaining (reduced) output space.

polyphonic

[this module is RateSmart [1]]

Dynamic level type switcher

Select two different output types and switch between the types with the select input. A low vlue selects the left type on the left output and the right type on the right one. A high select input toggles that.

The rate of type change can be controlled with the slew contol.

MixingScaler

Fourfold mixing level scaler

version 1

polyphonic

[this module is RateSmart [1]]

Fourfold mixing level scaler

Each input will be multiplied by it's set gain and then it's offset will be added to obtain the output value.

There is a knob tracking control which can be set into off, lock or mirror mode. In off mode both knobs move independently, in lock mode they will move in tandem and in mirror mode when one goes up the other will go down.

The mute button will set the output to zero when active.

The four scalers are summed and sent to the sum output. The summed output level can be trimmed with a knob and a chain input is being mixed in. The sum output can be muted independently of the input mutes.

ChangeDetector

Change detector

version 1

polyphonic

[this module is RateSmart [1]]

A change detector

This module detects it's input being changed. When a change occurs a pulse is being output on the trig output and the amount of change is being sent to the out output.

The norm / abs selector determines whether the value (norm mode) or the absolute value (abs mode) of the change is put onto the output.

150 ScaledClip

Page: Ctrl1 [type 377]

ScaledClip

Scaled clipper

version 1

polyphonic

[this module is RateSmart [1]]

A scaled clipper module.

The input values are converted according to the input type setting, and assumed to be in the range [-1.0,1.0] then. These signals are then multipled by the current level setting and clipped to a range [-1.0,1.0]. The result of that is then scaled to the wanted range by applying the out type selection.

The idea is that when a triangle wave is being processed the result will be a trapezium shaped wave, but it can be applied to all wave forms to get a signal that spends more time at the extreme values.

When the set level gets negative (by setting the level modulation to a negative value) the resulting output wave will be inverted.

151 RateConverter

Page: Ctrl1 [type 379]

RateConverter

Rate converter

version 1

polyphonic

A rate conversion module.

This module is controlled by it's slave input, which is suppoesed to be connected to a MidiClockIn or a Tapper module. The slave output will just pass this signal on.

The rate multiplier controls the scaling applied to the control output, it will make controlled LFOs go faster or slower by some factor.

The control output can be used some different kind of controls. It can either control an LFO which is set to fast 0.254, medium 2:05 or to BPM mode; a Delay set to 3s or 5 min, or it can control the ClockGen module's BPM value.

The slave in and output can be used to chain up several MidiClockIn, RateConverter or Tapper modules, the first one in the chain will be the master controlling all other Tappers. Other tappers can be set to different control modes to get LFOs and delays synced up properly at different rates.

With the blue input next to the rate multiplier knob the rate can be modulated, it's value will be multiplied by the knob set value. Note that the internal values for the knob range from -23 for the / 24 setting trough 0 for the X 1 setting to 24 for the X 24 setting - so for effective modulation set the rate to X 24. Only whole valued rates will ever be created, or a reciprocal of while values. The modulation input is internally clipped to a range [-1,1]. A values module would be suitable to control it. When unconnected the assumed modulation value is 1.

152 Rotator

Page: Ctrl2 [type 309]

Rotator

Rotator

version 1

polyphonic

[this module is RateSmart [1]]

This module rotates it's input vector (in1,in2) over an angle 2 * PI * angle to calculate an output vector (ou1,out2).

This can be used to make a rotating stereo image for instance, or with an input vector of constants, say (0,1) and the angle driven by a saw signal it will make a sine and a cosine on the outputs (quadrature signal).

I've added a mode selector, in the sin/cos mode the mode operates as before while in rhee sin/-sin the left input is multipled by 1 + sin( 2 * PI * angle) and the right input by 1 - sin( 2 * PI * angle)

The s/c outputs in the sin/cos mode output sin( 2 * PI * angle) and cos( 2 * PI * angle) and in sin/-sin mode that would be sin( 2 * PI * angle) and -sin( 2 * PI * angle). These outputs can be scaled by the sctype selector to be normal, inverted, positive only, etc. In positive only mode they are suitable to modulate the delay length of a delay module, this is meant for creating leslie type effects.

Rectifier

Rectifier

version 1

polyphonic

[this module is RateSmart [1]]

This module rectifies it's input signal, either half wave or full wave. In half wave mode only the positive part of the input signal goes through, for the negative part the output will be zero. In full wave mode the output signal will be the absolute value of the input signal.

The inv. output has the inverse signal from the regular output, i.e. it will be negative only.

There also is a transparent mode, in this case the output will follow the input and the inv. output will be the inverse of the input.

A slew rate limiter, or control rate low pass filter.

This module can be used to smooth jumps in a control signal.

In single mode the up control controls both the upwards and the downwards slew, in dual mode the down control comes in to make the down slope differ from the up slope.

Modulation is multiplied by the knob value, unconnected modulation inputs are set to a value if 1.0

160 ChebGen

Page: Ctrl2 [type 326]

ChebGen

A Chebyshev polynomial generator, frequency multiplier

version 1

polyphonic

[this module is RateSmart [1]]

A Chebyshev polynomial generator

The first output has an order two polynomial, for every subsequent output the order is on higher.

An order zero Chebyshev polynomial would be a constant 1, and order one would just be a copy of the input signal.

Similar tricks can be used for triangular and saw shaped waves, and those were implemeted as well.

This module can be used for frequency multiplication, the type of the input signal (sine, tri or saw) has to be set up correctly for that. In general the phase of the ouput signals will not be the same as the input signal .. as in they will not go trough zero at the same time.

RateMult

Square wave rate doubler

version 1

polyphonic

Square wave rate multiplier.

The rate of the incoming square is being doubled, the pulse / pause information is lost as each edge is translated into a pulse.

This module can be cascaded to get repeated rate doubling.

When the pulses do not 'fit' after rate multiplication eventually a counter will overflow. This will result in an endless stream of pulses with a glitch once every 4 billion pulses or so.

SawMill

Saw Mill

version 1

polyphonic

[this module is RateSmart [1]]

A Saw Mill

This module performs frequency multiplication on a saw wave. The multiplication factor can be non-integer, but the saw wave must have an amplitude range [-1.1] for this to work. Some input output scaling for various standard ranges is present.

The calculation used is : out := FloatMod( M * ( in + 1), 2) - 1; where M, the multiplication factor, can be set and modulated.

For non saw inputs some other 'interesting stuff' will happen.

163 AmMod

Page: Ctrl2 [type 351]

AmMod

AM RM modulator

version 1

polyphonic

[this module is RateSmart [1]]

An AM / RM modulator

The in signal is multiplied by a scaled version of the mod input and then sent to the output.

Scaling is applied first on the level shifted mod signal, then the offset is being added.

So the modulation depth is controlled by the mod knob, and an offset can be added so the modulation does not have to go down all the way to zero.

The AM / RM control fades between Amplitude and Ring modulation (or balanced modulation) types.

AM is multiplication by a positive only signal, and RM is multiplication by a bipolar signal.

The mod input is first converted into a bipolar signal for the RM bit and then that signal is internally converted to an unipolar signal for the AM part.

The FX mod controls can be used to fade between AM and RM.

164 WaveWrapper

Page: Ctrl2 [type 325]

WaveWrapper

Wave wrapper, wave shaping

version 1

polyphonic

[this module is RateSmart [1]]

A wave wrapping / folding module.

When the input signal is larger than the high level it is reflected back, likewise when lower than low level it is folded back as well.

For type I the output is normalized to produce a signal in the range [-1,1].

For type II the output is not normalized, and the output swing is determined directly by the set low and high mirror controls.

For type III things work different a bit. This is my take at the smrl variation as found in the link from the previous section. The wrapping is as for type 2, except that the modulation is not used to change the mirrors and the folded signal is not sent to the output. What happens instead is that when the folder changes direction the modulation signal is being added to the current output signal. When the output signal goes over 1.0 it is reset to -1.0. Also the modulation works different in this case, the modulation input and knob are added for this mode instead of being multiplied.

Wavolver

Wavolver

version 1

polyphonic

[this module is RateSmart [1]]

A pulser module.

After an idea from http://ijfritz.byethost4.com/sy_cir6.htm

When the absolute value of the signal input is larger than the level at the shape input the the signal input is passed to the output, otherwise the output is zero.

Both signal and shape output have a level and an offset control.

When the output is zero the 'inact' output will go active. This can be used to activate a wave wrapper module for instance, to get a full implementation of the Ian Fritz idea.

169 DataGraph

Page: Ctrl2 [type 1115]

DataGraph

Data graph

version 1

polyphonic

[this module is RateSmart [1]]

This is a lookup module, basically. The input value moves a cursor over the horizontal axis and the looked up graph height is then sent to the output.

To use the module as a sequencer the ClockGen2 module can be used to control it's in (from the ClockGen2 saw output) it's quant (from the ClockGen2 quantisation output) and it's time divisions (from the bars output).

Points can be added by double clicking (or with ctrl+click) in an empty area. The same action on an existing point will allow that point to be moved or removed - removal being a move to somewhere out of the graph area.

The leftmost and rightmost points can not be removed, but can only be moved up or down.

Although this module can be used at audio rates it is not being anti aliased, so drawn wave forms played as audio will give some serious aliasing.

A right click on the graph area will popup a context menu allowing for some standard wave forms to be created, basic symmetry operations and save to and load from file.

The view and lookup mode can be set as linear, splines, steps or dots.

There is a chg (changed) output which will pulse whenever the output value changed. This is usefull mainly in the steps and dots mode, although when using the sync input all modes are usable.

Sync when not connected leaves the module under full control of the in input. when sync is being connected and pulsed the output value and the chg (changed) output will be synced to the sync signal. The sync input is normal level logic (that is smaller than or equal to zero is low and greater than zero is high (that way it can be synced from, say, a sine LFO output (in bipolar mode))).

The inv and rev inputs can inverse (play upside down) and / or reverse (play right to left) the playing mode.

The rnd button changes all values, not their positions. Likwise the three rnd inputs change vertical positions only, the leftmost alters one at random, the moddle one alters 25% of the values amd the rightmost one does the same as the rnd button - it alters all.

The amount of grid lines can be set with the up down buttons, the top one for vertical lines (x - horizontal divisions( time)) and the bottom one for horizontal lines (y - vertical divisions (value)). The horizontal divisions can also be controlled from the ClockGen2 module.

The sync input supports the special NOT_CONNECTED status.

170 Values

Page: Ctrl2 [type 358]

Values

A number sequence quantizer

version 1

polyphonic

[this module is RateSmart [1]]

A number sequence quantizer.

In the values box a number of comma separated values can be entered. The first and the last value are not being used to generate output values but they define the number range to be used.

This range will be maped to an internal output range of 0 .. 1. Also the mumber of values is counted (minus 2 for the unused last and first values), and this value will be mapped to an internal input range of 0 .. 1.

Now when the internal input value is 0 the first element of the value list (which is the second number in the list) will be selected, and when it is 1 the last element (which is the one but last value in the list), and for input values between 0 and 1 numbers between the first and last will be selected.

The selected number will then be translated to an output value using the determined output scale.

An example : say you enter 0, 0, 1, 3, 4 into the values box, so there are three values (0, 1, 3) and the range of values is 0 .. 4.

The input mapping then is such that input values of 0 .. 1/3 will result in the first value of 0 to be selected, likewise 1/3 .. 2/3 select the value of 1 and 2/3 to 1 will select the last value 3.

Now the selected values will be scaled too, such that the range 0 .. 4 is mapped to a range of 0 .. 1. So the selected value of 0 results in an output of 0/4, 1 yields 1/4 and 3 makes 3/4. The values 2 and 4 are not in the list so 2/4 and 4/4 will never be generated.

Now all this scaling is internal scaling, and an input mapping is applied before and an output mapping is applied after (with the two signal type selectors). This may get a bit confusing, but usually you'll want the 'positive' signal type (which effectively does not do any pre or post scaling).

This module can be used to select a number of pre selected values, for instance the SwanSong module has maze type modulation. Now you probably would not want to use all the possible maze types for the selection. For that control you could set the range from 0 to the number of maze types minus 1, and then between those values enter the indices of the ones you want to select from.

So when you have maze types Sierpinsky (0, indices start at 0 always), Penta(1), Hepta(2) ans Squest(3) and you want to only use Penta(1) and Squest(3) enter a string of 0, 1, 3, 3. An input value of 0 .. 1/2 wil then select Penta and 1/2 .. 1 will select Squest.

The minimum useful number count would be 3, which then would would always select the middle number and that number would be scale according to the range set by the first and last number.

All unusable ranges will result in an unscaled output value of zero.

All unparsable strings will result in an output value of zero.

The list has to be a series of numbers (which can be fractional or negative as in 0.1, -0.33333, 2, 5.176) separated by commas. Any white space is for readability only and will be stripped before interpretation.

The numbers between the first and last can be outside the range defined by the first and last. The last number may be lower than the first one, it will just invert the sequence effectively. The first and last numbers must differ though or otherwise a scaling can not be calculated (resulting in an output of 0 and the displayed selection value to be set to -1).

So, it is possible to make this module generate arbitrary numbers, just enter the first value as zero and the last value as one. The inbetween numbers will then essentially be unscaled.

171 Sieve

Page: Ctrl2 [type 370]

Sieve

A number sieve

version 1

monophonic

[this module is RateSmart [1]]

A Xenakis like number sieve.

I may be more like a generator, nomenclature.

Wren's notation for basic modules is:

* [n,m]       : a sieve module with modulus n and residue m [3,1] -> {1,4,7...}.
* random(f)   : a sequence of random numbers, f selects the chance for any number to be present in the sequence. 0 <= f <= 1, f.i random(0.33)
* fibonacci   : the fibonacci sequence {0,1,1,2,3,5,8,13...}.
* prime       : the prime numbers {2,3,5,7,11,13...}.
* {numbers|n} : a litteral number sequence, f.i. {1,5,13,14,21|24} n is the modulus, 24 in the example.

These can be combined using the following operators:

* \+ : the union of two sieves: [3,0]+[4,0] -> {0,3,4,6,8,9,12...}, the numbers combined (or function).
* \* : the intersection of two sieves: [3,0]*[4.0] -> {0,12,24...}, the numbers present in both (and function).
* ^ : the symmetric difference of two sieves: [3,0]^[4,0] -> {3,4,6,8,9,15...}, the numbers in one but not in the other (xor function).
* ! : the complement of a sieve: ![3,0] -> {1,2,4,5,7...}, the numbers not in the sequence (not function).

Parenthesis can be used to enforce an evaluation order, f.i. as in (([3,0]+4,0)*fibonacci)+prime to first evaluate the left +, then the * and the right + last.

A simplified formula will be calculated when the the formula changes, or when the external period changes. The simplification does not use prime decomposition, it will compute a sequence and from that it will make a sequence of modules joined through union.

The evaluate input will force reevaluation of the formula, this can be useful when a random module is present to obtain a new random sieve.

Otherwise this module functions like the Values module, except that the start value will always be 0 (zero) and the end value is set by the external period.

The difference (top) output will output differences between sieve sequence values, in case the last sequence value was selected it will be the value of the last minus the first element (this cyclic behaviour was not present in the original concept).

Negative numbers can not be used in sieves, the random sieve's probability control is the only floating poin number being used.

The simplified formula is displayed above the user supplied formula, or an error will be displayed when the user supplied formula could not be parsed.

The currently selected sequence value is displayed right of the changed output.

The changed output will go active when the ouput value was changed, the difference output may not have changed then.

The regualar (bottom) output will be scaled such that the external period results in an internal output of 1, this can be changed then with the output type selector.

The difference (top) output will be scaled such that the largest difference value present will result in an output value of 1, again this can be rescaled using the output type selector.

For more information on the subject try googling for Xenakis sieve, or Xenakis sieve algorithm. It may find a 221 page paper by Dimitrios Exarchos (Iannis Xenakis and Sieve Theory), I've founde that to be a very useful text.

        | Term '+' Term             // Union of two terms
        | Term '*' Term             // Intersection of two terms
        | Term '^' Term             // Symmetric aifference of two terms
        ;

Term    = '[' Module  ']'           // Modulo residue sieve

174 Noop

Noop

nop

version 1

polyphonic

[this module is RateSmart [1]]

Noop, this module does nothing .. except it provides one sample (control or audio rate, as the module is rate smart) clock of input to output delay. It can be handy for routing signals at times.

It has one usefule feature though, the input when not connected to anything holds the special value NOT_CONNECTED, which will be passed to the output.

Several modules have special behaviour when their inputs are not connected, so when you pass them the NOT_CONNECTED value such inputs will be seen as unconnected. HAving a module that can output NOT_CONNECTED makes it possible to switch under patch control from connected to unconnected, by passing both a real connection and the output of the noop module (with unconnected input) to a switch.

So the noop module doubles as a special NOT_CONNECTED generator. It is best BTW to only use this on inputs that detect the unconnected status - as the the NOT_CONNECTED signal actually is very big!

The inputs support the special NOT_CONNECTED status.

176 ProbGraph

Page: Ctrl2 [type 1121]

ProbGraph

Probability graph

version 1

polyphonic

[this module is RateSmart [1]]

A probablity graph

With the graph tool a cumulative random distribution function (crf) can be set up - with a little twist.

The distribution is being used by an internal uniform random generator (all values of 0.0 to 1.0 being equally probable), the looked up value will then have the distribution as laid out by the graph. This gives graphical control over how likely output values will be.

On every trig (sync) input pulse a new value will be output and when the value changed a trigger out puslse is being generated as well.

For the graph the leftmost point is fixed at the bottom left corner and the rightmost point hangs in the top right corner - external scalling can always be applied with a mixer or amplifier module.

The twist is that the X and Y axis are being swapped from what woud be expected for a crf, so the uniform random is distributed along the X axis and the Y axis represents the output values.

Output polarity can be set with the selector button ([-1,1], [-1,0] or [0,1] and the inversions thereof), the shape of the graph can be linear, splines, steps or dots. For conveniance the grid marks can be set to severla values.

polyphonic

A note quantizer module

the input value is quantized to the nearest note selected by the the buttons, when no notes are selected the input is passed unchanged, and when a lower and a higher note are equidistant from the the input value the higher value prevails.

This assumes a 12TET scaling with middle A having note number 69 (or middle E having 64, or middle C having 60).

There is no maximum or minimum on the input signal.

A scaling of 128 notes / unit is used.

The range control attenuates (or inverts) the input signal.

Scales can be selected from a preset and the presets will be dynamically loaded from a file wren.scale that must be in the same folder as the Wren executable file. When this file does not exist Wren will create it. After that you can edit it with a text editor (like Notepad for instance) and Wren will not touch it anymore.

A scale can be altered manually with the note buttons, but that may get you locked, as once when a custom scale is in effect the preset will not work anymore. You can use the enforce button to fix that, it will set the currently selected preset. The mudule show a scale name in case it happens to know the note combination, or Custom when it does not, or Transparent when no notes at all are selected - in this case the input passes unquantized to the output.

A transposition can be applied to the selected scale with the transpose control. Note C4 is the 'neutral' base note (not leading to any changes). Transpositions are not reflected in the shown note pattern.

Note: The inv2 output will follow the set scale, the inv2 output will not. Both are an invesion of the regular output and both play notes from the same octave as the regular output is in.

When the transparent input is active the range scaled in summed with the chain input is passed on to out and the inversion outputs then both hold 1.0 - out. This will also happen when the scale input is set negative (but unequal to NOT_CONNECTED).

The scale input supports the special NOT_CONNECTED status.

This can be used to scale a value sig into the range [0,1] when you have a minimum value and a maximum available value for sig.

[this module is RateSmart [1]]

A base 2 logarithm module.

First the absolute value of the input is taken, when it is >= 1/8 the base 2 logarithm is being calculated and then 1.0 is being added, when the absolute input value <= 1/8 the output value is -2.0.

Thus an input range [1/4 .. 1] results in an output range [-1 .. 1], it is the inverse of the Power2 functionality (with some constraints).

The mute button will set the output to zero when active.

Gate

Logic functions

version 1

polyphonic

[this module is RateSmart [1]]

A logic AND. NAND, OR, NOR, XOR, XNOR, ONE or NONE gate module.

The AND. NAND, OR, NOR, XOR and XNOR gates have been generalized to operate on multiple bits, this works by quantizing the input values into a selectable number of bits (1 bit gives the old behaviour) and then performing the logical operation on the resulting bit vector.

The XOR and XNOR ports operate like cascaded ports, which makes them behave like and odd or even parity generator respectivly, the output being active when an odd number (or an even number) of inputs are active.

The ONE port activates it's output when precisely one input is active, the NONE port is the same with an inverter added at it's output. These two port types do not generalize to bit vectors.

When the bit size is set different from one the input signals are AD converted to the set number of bits, after that the logic function is applied and then the signal is converted back to an analog signal. When for instance only one input is being used and the module is set to 'OR' mode and the input value is in the range [ 0, 1] this will result in a quantizer function being performed (with four possible output values in two bit mode, eight in three bit mode, etc., and of course in one bit mode it will have two possible output values).

For the 1 bit mode the following function table applies:

polyphonic

[this module is RateSmart [1]]

Phase detector, a building block for a digital Phase Locked Loop. This is modeled after the CMOS CD4046 type I and type II phase comparator, and it adds a filter as external three state outputs are not possible.

The out output is the filtered phase detection output. The output will go up when the frequency on the sig in input is higher than the frequency on the cmp in input, the other way around it will go down and when the frequencies are equal it will stay where it is.

To use this module you should connect an oscillator's FM input to the output of this module, and then connect the Oscillator's output to the cmp in input of this module.

The type I comparator is an XOR function, the type II comparator is a larger state machine that actually implements a 'phase frequency' comparator. Type III used analog multiplication of the input signals (a double balanced mixer).

MultiCompare

Stacked window comparator

version 1

polyphonic

[this module is RateSmart [1]]

A stacked window comparator.

Eight levels can be set, where each level is internally added to the previous to create a set of ranges. When the input signal is within one of the ranges it's output will go active.

The input level is internally multiplied by four before comparisons take place, and additionally it can be further scaled with the input level control (which can add an additional multiplication by a factor of four). The level modulation input value is multiplied with the input level as set by the knob.

Each individual output can be routed to one of three output buses.

The 'rnd' button will randomize the positions of the comparator level knobs, the 'clr' button sets those pots all to zero.

Note: the individula outputs are high logic ( 0.0 for false instead of -1.0, and still 1.0 for true)

245 PulseDelay

Page: Logic [type 614]

PulseDelay

Pulse delay

version 1

polyphonic

[this module is RateSmart [1]]

A logic pulse delay module.

This module can operate in three modes:

Pulse stretch mode : an incoming pulse will be stretched to the set delay time, or when it is longer than tat it will be truncated. That is the ouput pulse start when the input pulse starts, but it ends when the set time is over, no matter what the input did. This makes changes to the positive part of the incoming signal only.

Pulse delay mode: an incoming pulse will be delayed by the the set time. This will move the entire pulse in time, so it's length will not be changed. This will shift both the positive and negative parts of the incoming signal.

osc mode : when the input is active pulses will be generated continuesly at the set pulse duration rate and whe nthe input is inactive thou output will be off.

The delay time can be modulated from the delay time modulation input, the amount of modulation can be set with the knob.

This module has the same ranges as are used for envelopes, except that the module can be set to run at audio rate. When running at audio rate the set time will be eight times shorter as compared to running at control rate.

In Delay mode only one pulse can be handled properly, meaning the module cycle has to be finished before a new one gets handled properly. When you need to delay a pulse train an audio delay module should be used.

In Stretch mode, when a next pulse comes in before the current one is finished it will be ignored.

The output indicator shows the internal logic output state, this can be modified with the output type control to determine thaa actual values being sent out.

The other indicator shows module activity, e.g. when it is actively stretching, delaying or oscillating.

PulseSkip

Pulse skipper

version 1

polyphonic

[this module is RateSmart [1]]

A pulse skipping module.

The current level of the input is compared to the current compare (cp) level, when it is larger incoming pulses will be passed on to the output and otherwise they will be skipped. Only complete pulses will be passed on, so the ouput will always be in sync with the trig signal.

The levels are computed as the input value times the modulation added to the preset level as shown in the display.

The res iput when going active sets the ouput off. The trig input when going off sets the output to off as well.

The output signal type is selectable.

Rungler

Rungler

version 1

polyphonic

[this module is RateSmart [1]]

A rungler module.

This module was modeled after an idea by Rob Hordijk, he used this circuit in his Benjolin device. The length of the shift register can be set from 3 to 64 (the original uses 8) and the number of taps can be set from 1 to 8 (the original uses 3).

The idea is to clock the module from an oscillator and to provide data from another oscillator, the output of the rungler is then fed back to the frequency control input of the data oscillator. This way short varying patterns will be generated. The shift register length matters not much, but it should be set larger than the number of taps used. The number of taps determines the number of distinct levels present in the output signal.

[this module is RateSmart [1]]

A cascadable logic shift register

The register is 32 bits long, and it can be chained using cil (carry in low), cih (carry in high), col (carry out low) and coh (carry out high).

Input from the in input will be XORed with either the cil or cih signal before being added at either the left or the right side of the internal shift register.

A shift is being made on each upgoing edge of the trig input. Shifting can be to the right or to the left depending on the rev (reverse) input. The unreversed direction is from left to right (that is 0 to 1 to 3 etc.).

The indicator bar shows the lowest bit on the left side (same direction as the outputs).

When the free / clocked selector is in the free position reset is immediate, otherwise it will be synced to the trig input.

With the T/G mode selector the outputs can be switched between triggered and gate mode, where gate mode makes overlapping pulses and trigger mode ands the outputs with the trig signal. The carry outputs are always gated.

The change inputs are sampled on a rising step input, so a change will occur when such an inpujt is active at the momenent the step input goes from low to high.

SeqRandVal

Random value sequencer

version 1

polyphonic

[this module is RateSmart [1]]

A random value sequencer.

Will play a sequence of random values with a set length, a set lowest value and a set highest value. The base control can offset the selected values.

A low to high on the trig input will play the next value and a low to high on the random input will select a new random sequence.

The quantize function can be turned on or off, When it is turned on the random values will be quantized to note fractions as selected by the notes control. When it is off the raw internal values are used. the value from the chain input will just be added to the computed output, it will never be quantized.

The slew function implements an exponential moving average filter which can be applied either pre- or post- quantizer.

Morse

A Morse code generator

version 1

polyphonic

Notes about polyphony: The text is shared over all voices, the position in the text can differ per voice.

[this module is RateSmart [1]]

A Morse code generator.

Input text is translated into an off pattern on the output connector at a speed determined by the incoming clock signal.

The Reset input will make the sequence restart from the beginning.

When the sequence ends it will repeat from the beginning.

The blue output genrates note values 0 to 7 based on a primitive implementation of SolReSol.

This module can use input from a file by typing :

file:fillename

or

file:fillename regular-expression

The last non-empty line of the file will be read (or an error message will be returned) and that line will be filtered with the optional regular expression.

When the regular expression contains a group named 'result' that will be the matched bit from that last line.

Example:

X:\filedir\filename.log (?:msg\s\[)(?<result>.*?)(?:\]\shost)

pointing to some file on drive X: with a specified filter which has a group named
'result' (and two other unnmaed groups of stuff we are not interested in).

the last non empty line of the specified file could be (this is from a log of an IRC
chat session, a priviat message from jan to group #electro):

  '2022-02-09 01:30:23.784 | priv : [jan -> #electro] msg [pwew .. filter is hard o_o] host [~jan@xxx-xx-xxx-xxx.yyy.zzz.nl]'

The regular expression   matches:  'msg [pwew .. filter is hard o_o] host'.
The named group 'result' matches:  'pwew .. filter is hard o_o'
and that in this case is the bit we want.

SeqSeq

Sequencer sequencer

version 1

polyphonic

[this module is RateSmart [1]]

A sequencer sequencer.

This module makes it easier to sequence sequencers. It assumes the controlled sequencers to be set to a length of of 16, and it assumes all controls to be obtained through this module. You will then add as many sequencers as needed for the wanted step count.

  • ResMod1 : issue reset out on received reset or when the step count is reached.
  • ResMod 2 : issue reset out on direction change.
  • ResMod 3 : issue reset out on both conditions above.

To set up sequenced sequencing you use this module as a controller. Clock it from some source, and maybe use the direction input and or the reset input. Then for every sequencer connect the res trig and dir outs to the corresponding inputs of the first sequencer in a sequencer chain. Every next sequencer should be chained from the preceding one. The act ins of the sequencers go to successive outputs of this module.

259 Seq16

Page: Seq1 [type 1211]

Seq16

16 steps sequencer

version 1

polyphonic

[this module is RateSmart [1]]

A 16 step sequencer for values and for notes.

It can be set to various signal types.

A cross fade utility is implemented to smooth the signal from one step to the next, cross fading works on all four X outputs, the R outputs are not cross faded (Raw).

Smoothing slope type can be set independently for up going and down going signals to eiher exponential, linear, logarithmic or s-shaped.

This module can be used as a complex envelope generator when properly clocked.

The four outputs are all offset by four steps each, so when output 1 is at step 5, output 2 is at step 9, output 3 at 13 and output 4 will be at step 1.

The chain input is being used on all four outputs when the module is not active (as controlled by the act input).

The sequnecer can be set to run reversed with the dir input, and it can be set to inverse mode with the inv input. Inverse mode being that the slider is read out upside down.

There are three random inputs which will set the sliders to random positions when going active, 1 for one value, some for some values and all for all value.

There are three clear inputs which will set the sliders to zero positions when going active, 1 for one value, some for some values and all for all value.

When the hold input is active the sequencer will still step but will keep the ouptut values frozen, this differs from what the act input does, that one freezes everything.

Skip inputs when active will skip the corresponding step to be used, making the sequence a step shorter. When all steps are skipped the sequencer will stop moving.

The clock skip input, when seen active will cause a clock (trigger) action to not be executed. This differs from the inactive mode in that in inactive mode the sequencer passes on the chain inputs and when the clock is stopped the output will no longer change at all.

The shf (Shuffle) input will shuffle the values for the steps on gong from inactive to active.

The steps output for the current step will go active when the sequencer is active and either the trig input is high or the T(rigger) / (G)ate mode is set to G.

The TimeWarp (tw) output, which can be used to control the speed of a driving clock module, it is meant to drive the speed input of an LFO. The idea is that when steps are being skipped the sequence length can be kept the same`when using the TimeWarp output in this manner.

The changed outputs (in the C column) will pulse briefly when the associated sequencer output changes.

The outputs below the res, dir and act inputs just copy tose inputs.

The res input is a synced reset, it will only reset when the signal is active on a low to high transition of the trigger input.

The a-res input is an unsynced reset, it will always reset the module when the signal goes from low to high.

It can be set to various signal types.

A cross fade utility is implemented to smooth the signal from one step to the next, cross fading works on all four outputs.

Smoothing slope type can be set independently for up going and down going signals to eiher exponential, linear, logarithmic or s-shaped.

This module can be used as a complex envelope generator when properly clocked.

The chain input is being used on the output when the module is not active.

The sequnecer can be set to run reversed with the dir input, and it can be set to inverse mode with the inv input. Inverse mode being that the slider is read out upside down.

There is a random input which will set the sliders to randm positions when going active.

When the hold input is active the sequencer will still step but will keep the ouptut values frozen.

Skip inputs when active will skip the corresponding step to be used, making the sequence a step shorter. When all steps are skipped the sequencer will stop moving.

The clock skip input, when seen active will cause a clock (trigger) action to not be executed. This differs from the inactive mode in that in inactive mode the sequencer passes on the chain inputs and when the clock is stopped the output will no longer change at all.

The trig step output for the current step will go active when the sequencer is active and the trig input is high. trig is the logical or of all the individual trig step outputs. The main trig output will trigger in the per step set trigger mode (n, s, a or g - see below)

The TimeWarp (tw) output, which can be used to control the speed of a driving clock module, it is meant to drive the speed input of an LFO. The idea is that when steps are being skipped the sequence length can be kept the same`when using the TimeWarp output in this manner.

With the counts controls the number of clocks per step is set. The amount can be modulated.

The modes are trigger modes and can be n - none, s, single, a - all and g - gate. The mode can be modulated.

The res input is a synced reset, it will only reset when the signal is active on a low to high transition of the trigger input.

The a-res input is an unsynced reset, it will always reset the module when the signal goes from low to high.

The stepmod inputs support the special NOT_CONNECTED status (blue row under counts).

261 LUT

Page: Seq1 [type 1215]

LUT

Lookup table

version 1

polyphonic

[this module is RateSmart [1]]

A lookup table module.

The select input selects one of the faders (or a mix of two when cross fading is in effect) to be sent to the output.

This can also be used as a sequencer when controlled with a saw or triangle shaped signal on the select input.

The four outputs are offset by four steps each, when output 1 outputs step 5, output 2 will output step 9, output 3 step 13 and output4 step 1. Cross fading works on all four outputs.

The steps selector selects the number of steps to use for an input going from zero to one.

The blue inputs below the faders modulate the fader values. When not connected they will have a value of 1. When connected and the xfade control is set to one these inputs will make for a 16 step piecewise linear interpolation processor (processor as opposed to shaper).

262 SeqChord

Page: Seq1 [type 1216]

SeqChord

Chord sequencer

version 1

polyphonic

[this module is RateSmart [1]]

A chainable chord sequencer.

The chord to be played is determined by the leftmost active input, when nothing is active the input signals (both blue and green) will be passed on (to make the module chainable).

When a chord is active the green outpurts will all follow the gate input.

So to use this module you will have to provide a clock signal on the gate input and then make ups some pattern on the active inputs to determine which chord will be played.

When you do not want to use the green gate outputs (meant to trigger an envelope) you do not need to apply a gate signal.

The blue outputs are meant to control frequency inputs of oscillators, and the green outputs are meant to control envelope generators.

The active inputs can be controlled to determine the sequence of the chords, the module will not self-step.

263 ProbSequencer

Page: Seq1 [type 1214]

ProbSequencer

Probabilistic sequencer

version 1

polyphonic

[this module is RateSmart [1]]

A probability based sequencer.

For each note the probablility with which it will be played can be set with a slider (and this value can be multiplied by the vlue on the associated input). Notes have to be be enabled before they can sound, and note enables can be selected from a scale preset.

The presets will be dynamically loaded from a file wren.scale that must be in the same folder as the Wren executable file. When this file does not exist Wren will create it. After that you can edit it with a text editor (like Notepad for instance) and Wren will not touch it anymore.

A transposition can be applied to the selected scale with the transpose control. Note C4 is the 'neutral' base note (not leading to any changes). Transpositions are not reflected in the shown note pattern.

A selected scale can be altered with the note buttons, and such a change will be saved with the patch (making the shown scale preset name meaningless, of course).

The rnd button will set a random probability distribution, the clr button will set a flat distribution. The distribution can be altered with the tilt control. A zero value means that there is no tilt, a positive value maked higher notes more likely to be selected and negative values will produce more low notes.

A transposition can be applied to the selected scale with the transpose control. Note C4 is the 'neutral' base note (not leading to any changes). Transpositions are not reflected in the shown note pattern. The low and high note controls limit the range of possible notes.

The sm(oo)th controls determine the likelihood that the next random value is about the same as the current one.

264 Seq32

Page: Seq1 [type 1229]

Seq32

3 x 32 or 1 x 96 note sequencer

version 1

polyphonic

[this module is RateSmart [1]]

A 3 x 32 or 1 x 96 note and gate sequencer.

There is a separate selection for notes and octaves.

Note durations can be set to multiples of 1/16 of the input clock.

In free mode there are three different play clocks, so all three outputs can run at a different rate. In 1 x 96 mode this also means that one sequence can overtake another.

In sync mode only one clock (the top input) is being used and the sequencers run in sync in 3 x 32 mode and the play pointers have a constant difference in 1 x 96 mode. This also means that note durations have to be interpreted differently, in sync mode it is the duration of the active part, and each step will have a duration of 16/16 clock pulses.

The trigger mode can be trig, gate or repeat. In trig mode one short output pulse is generated on the clk O outputs. In gate mode it will be a long pulse, and in repeat mode there will be several shirt pulses.

The dir input when active reverses the direction in which the sequencer runs. The invert input when active will play the sequence "upside down".

265 Pattern

Page: Seq1 [type 1213]

Pattern

A rhytmic pattern generator

version 1

polyphonic

[this module is RateSmart [1]]

A rhythmic pattern generator.

This is implemented as a sequence of logic dividers.

With each divider you set a note length, at each start of a note an output pulse will be passed from the trig input. Then the divider starts to count, and when done, the next step will be processed. When a divider is set to zero that step will be skipped, and when all dividers are zero there will be no output pulses.

Added mode selection to each step. Mode can be set to normal (nrm) to get the behavior described above. It can be set to random mode (rn1) to to get a random count [0,Steps]. Weighted random (rn2) will give divisions by two of the set number of steps, likewise rn3 uses divisions by 3. Skip mode will skip the step.

The step outs will produce a 'per step' copy of the main output.

This module can be used to make rhythmic figures.

Vcps

16 steps voltage controlled pattern sequencer

version 1

polyphonic

[this module is RateSmart [1]]

A 16 step sequencer for values and for notes with voltage controlled patterns.

It can be set for various signal types.

The seqnuecer can be set to run reversed with the dir input, and it can be set to inverse mode with the inv input. Inverse mode being that the slider is read out upside down.

There is a random all input which will set the sliders to randm positions when going active. the random 1 input will set a random step to a random value. The clr input will set all steps to the zero position, or to middle A when the notes mode is active.

For each step a mode can be set, either on, off or adc. In on mode the step functions normally generates a gate and a trig output, in off mode it will not generate a gate or trig output and the last output value will be maintained. In adc mode the pattern input determines what will happen. This input is converted into a binary value and when the bit corresponding to the current step is on the step behaves as in on mode, it will behave like off mode otherwise. The pattern selection can be modified with the offset and gain controls. The adc uses gray codes, meaning only one bit will change from one step of the pattern to the next.

There are three outputs, out, trig and gate. the out one outputs the current slider value for the active step - for inactive steps it will not change value. The gate output outputs a logic high for active steps. The trig output ands the gate output with the trigger input, so it will pulsate for each active step.

267 MultiDiv

Page: Seq1 [type 625]

MultiDiv

Frequency divider

version 1

polyphonic

[this module is RateSmart [1]]

A set of divider sections with a builtin multiplexer.

The module consists of eight individually settable divider sections with a common clock.

The individual dividers all have their own output and on top of that there is a built in multiplexer selecting from the individual outputs and routing to the mix output.

The multiplexr is controlled by a sel input signal and it's start and span can be set and modulated as well.

The xfade input will fade over the set span starting at the seection start.

The idea is to clock this module with a relatively fast clock (for example the x16 output of the ClockGen module) such that steady patterns can be programmed with an occasional drum roll.

Using the xfade controls steps can be faded over to each other (instead of abrubptly being switched over).

Added a value control for each step with a mix output for it, this behaves like a set of multiplexed values, or like a sequencer.

Note: the xfade control does not make smooth transitions as output values will change value on a clock edge only.

Primes

Primes Rhythm generator

version 1

polyphonic

[this module is RateSmart [1]]

This module implements a Primes Rhythm player.

The steps selector sets the pattern length which can be modulated by the mod input.

Internally the module counts from one to the length of the pattern (and then jumps back to one)(or reversed) when the trig input goes active.

When the current count is a prime number the output will activate. The inv output makes the inverse pattern and it will fire when the count is mot a prime.

Both outs will deactivate when the trig input goes inactive again.

The dir input dwtermines the counting direction - counting up when unconnected.

A 1 to 11 step sequencer.

When the trig input goes from zero, or below zero, to a value above zero the sequencer will proceed one step.

When the dir input is positive the sequencer proceeds from left to right, from right to left otherwise.

When the res input goes from zero, or below zero, to a positive value the sequencer will be reset to the first step when the dir input is positive, or to the last step when the dir input is not positive

The top right input is a chain input, it's value is added to the value as set by the current step value.

Each step has an output that will go to logic true when the step is active, it is logic false otherwise.

There is a chain input available, it's value will be added to the sequencer output.

the rnd button will set a random pattern, the clr button sets all notes to A4.

270 TextSequencer

Page: Seq2 [type 1202]

TextSequencer

arbitrary length sequencer

version 1

polyphonic

A sequencer with an arbitrary amount of steps.

When the trig input goes from zero, or below zero, to a value above zero the sequencer will proceed one step.

When the dir input is greater than 0.5 the sequencer proceeds from left to right, from right to left otherwise. An unconnected dir input makes the sequencer run left to right.

When the res input goes from zero, or below zero, to a positive value the sequencer will be reset to the first step when the dir input is positive, or to the last step when the dir input is not positive

Control click on the display to get into the editor window where notes or values can be added (separated by commas).

In 'freq.' mode it is assumed that the module controls the 'freq' input of an oscillator, in this case the values can be either be values on which a modifier like Hz or s can be used, or it can be a note number. Time values like 1:39 or 1:33:00 can be used as well. Anything not understood is interpreted as a rest, the preferred way for entering a rest is to use an underscore character.

In 'arbitrary' mode nothing is assumed about what is being controlled and values entered will be output as is. It is still possible to use modifiers though.

It is possible to add a repeat count for a value by adding a number after it separated by a colon (:) character, a repeat will add some rests, that is, the note or value will be held and no gates are generated. Repeat counts of zero or less will result in the value being output once.

A rest results in the the previous output value being held and no gate output pulse will be generated for that step.

An example string for the 'freq.' mode would be: 'A1:2, 333 Hz:3, _, C1' first A1 will be output for two clock periods, then 333 Hz for 3 clock periods, then a rest for one clock period ( extending the 333 Hz signal for another clock time) and finally C1 for one clock period.

It is not possible to output a new value while suppressing he gate output.

When done with editing use CTRL+ENTER to close the editor and save the results, or ESC to close the editor without saving the changes.

There is a chain input available, it's value will be added to the sequencer output.

SeqStep

Sequencer step

version 1

This module implements one step of a chainable sequencer.

When the dir input is positive the step will become active when the forward trig input (the leftmost one) goes inactive, and it will stay active then for the amount of time set by the knob.

When the dir input is not positive the step will become active when the backward trig input goes inactive, and it will stay active for the time set by the knob.

The res input will make the step inactive when it makes a transition from non-positive to positive.

When the step is active the note set with the note selector will be set on the output, otherwise it will pass on the value it finds on it's top right input.

CsvData

16 channel CSV data player

version 1

polyphonic

This module implements a Comma Separated Values data player.

It reads the values to be played from a CSV file with up to 16 columns. The amount of lines to be read is limited only by available memory.

Data lines can have comment on them, comment starts with a # character and extend to the end of the line. When comment was found at the end of a line actually containing data that comment can be displayed in the module.

The module will output a new set of values on each rising edge of the clock input. When the Direction input is not connected or positive it will start with the first line of data, when the direction input is set to zero or lower it will start with the last line of data.

The module has two play modes, repeat and once. For repeat mode when the last data was output the module will then on the next clock restart with the first data line. When its set to once mode the data output will stop at the last line, it can then be restarted by issuing a reset signal (either a global reset or a reset signal on the reset input).

275 MidiPlayer

Page: Seq2 [type 1305]

MidiPlayer

A simple MIDI file player

version 1

monophonic

A simple MIDI file player.

The module can be in once or in loop mode.

In once mode the midi track will stop playing when it runs out of events or when an end of track MIDI event was seen. A reset will be needed to play the track again. When dome a Done pulse will be generated.

In loop mode the track will restart where the Once mode would stop, a Done pulse is generated still though at the track end.

Reset will always reset the track to the beginning, this can be a reset pulse on the rest input or a global rest (from the reset button).

All timing info except the track event timing is ignored. The track event durations set a counter that will be decremented on every clock pulse seen. When the counter reaches zero that event will be played. An input clock frequency of about 1 kHz seems to be a reasonable start value.

All other meta info is ignored as well.

Only note on and note off events will be played, a note on with zero velocity is treated as a note off - running status should be handled OK.

When there are non-track chunks in the file the file reader will probably misunderstand ... to avoid that use MIDI 1.0 .. I think ... or wait till I fix that.

276 SeqPattern

Page: Seq2 [type 1223]

SeqPattern

Pattern sequencer

version 1

monophonic

A pattern sequencer.

This is a sequencer meant to be used for drum patterns, it controls 24 drum lines at the same time.

A full drum pattern is composed of eight Parts (P) where each Part holds eight Sections (S). Each Section has eight Elements (E) and each Element has 24 Bits (buttons) which correspond to the Bit outputs.

Each bit can be in one of three states, it outputs nothing (thin white base line) it outputs a positive value while it is selected and the clock is high (a half block on the left side) or it outputs a positive value during the entire bit duration (a full block).

At any one time 24 bits are visible for each combintation of the current Part, Section and Element.

The sequencer is driven from the 'clk' input, but it only runs when the 'act' input is either not connected or when it is set to a positive vaue. the 'res' input, when going positive, will make the sequencer restart at Part 1, Section 1 and Element 1. The 'Res' button provides a manual reset.

The sequencer has two modes, 'Run' mode and 'Edit' mode.

In 'Run' mode:

The pattern will be played one Element at a time, moving to the next Element on the next clock. When all Elements were played a move is made to the next Section. Then when all Sections were played the next Part will kick in. This makes for a total sequence length of 8 x 8 x 8 = 512 steps. The active Part, Section and Element are indicated by a green color. When all parts were played it depends on the the mode what will happen next. In 'Loop' mode the sequencer jumps back to the beginning, Part 1, Section 1 and Elemment 1. In 'Once' mode there will be no further output and all the bit ouputs will be turned off. Red colored states are skip states and will not be played. Blue colored states act as a reset in 'Loop' mode and as an endpoint in 'Once' mode. When all Parts, Sections and Elements are red nothing will be played.

When a Part, Section or Element button is clicked the sequence will jump to that point on the next clock. Clicking on a red button will skip to the first non red one after it. Clicking after a blue point is possible, and will just jump to that point.

The active E, S and P buttons will be colored green. The skipped ones are red, the reset ones are blue and all others are gray. So when you see any green E, S or P buttons, you know the sequencer is in 'Run' mode.

In 'Edit' mode:

The progress of the sequencer is not shown in the P, S and E controls, but it will keep playing the same way as it does in 'Run' mode. The lights at the bit outputs will still show what is happening at the outputs.

You can select a specific Part, Section, Element combination with the P, S and E buttons, the button will turn yellow then to indicate selection. It is then possible to edit the 24 bit buttons without the sequencer running away from it.

The edit buttons ('copy E', 'copy S', 'copy P', 'clr E', 'clr S' and 'clr P') are functional. They will copy or clear Elements, Sections or Parts.

'copy E' will copy the previous Element to the selected one, when the selected Element is 1 nothing will be copied. 'clr E' will clear the 24 bits for that element to the off state.

'Copy S' will copy the previous Section to the selected one, when the selected Section is 1 nothing will be copied. 'clr S' will clear all bits in the current Section (that is eight tiems 24 bits).

'copy P' will copy the previous Part to the selected one, when the selected Part is 1 nothing will be copied. 'clr P' will clear all bits in the current Part (that is eight tiems eight times 24 bits).

Clicking once an E, S, or P button will select the associated Element, Section or Part (yellow). Clicking again will make the the button red, meaning it will be skipped on playback. Clicking yet another ttime will make it blue. Making a button read does not clear any bits. A blue button acts as a reset point, and making a button blue does not cler anything either.

Selected E, S, or P buttons are yellow. Unselected, non skipped and non reset ones will be gray. So you know that when you see any yellow E, S or P buttons the sequencer is in 'Edit' mode.

The 'res' button also works to reset the sequencer in 'edit' mode.

Sequences can be saved to disk and reloaded just as any module can - as a preset. Right click on the module and select load / save preset from the context menu.

277 SeqValues

Page: Seq2 [type 1224]

SeqValues

Pattern sequencer

version 1

monophonic

A pattern sequencer.

This is a sequencer meant to be used for control or note patterns, it controls 8 analog lines at the same time.

A full pattern is composed of eight Parts (P) where each Part holds eight Sections (S). Each Section has eight Elements (E) and each Element has 8 Vlues (sliders) which correspond to the outputs.

At any one time 8 values are visible for each combintation of the current Part, Section and Element.

The sequencer is driven from the 'clk' input, but it only runs when the 'act' input is either not connected or when it is set to a positive vaue. the 'res' input, when going positive, will make the sequencer restart at Part 1, Section 1 and Element 1. The 'Res' button provides a manual reset.

The sequencer has two modes, 'Run' mode and 'Edit' mode.

In 'Run' mode:

The pattern will be played one Element at a time, moving to the next Element on the next clock. When all Elements were played a move is made to the next Section. Then when all Sections were played the next Part will kick in. This makes for a total sequence length of 8 x 8 x 8 = 512 steps. The active Part, Section and Element are indicated by a green color. When all parts were played it depends on the the mode what will happen next. In 'Loop' mode the sequencer jumps back to the beginning, Part 1, Section 1 and Elemment 1. In 'Once' mode there will be no further output and all the value ouputs will be set to zero. Red colored states are skip states and will not be played. Blue colored states act as a reset in 'Loop' mode and as an endpoint in 'Once' mode. When all Parts, Sections and Elements are red nothing will be played.

When a Part, Section or Element button is clicked the sequence will jump to that point on the next clock. Clicking on a red button will skip to the first non red one after it. Clicking after a blue point is possible, and will just jump to that point.

The active E, S and P buttons will be colored green. The skipped ones are red, the reset ones are blue and all others are gray. So when you see any green E, S or P buttons, you know the sequencer is in 'Run' mode.

In 'Edit' mode:

The progress of the sequencer is not shown in the P, S and E controls, but it will keep playing the same way as it does in 'Run' mode.

You can select a specific Part, Section, Element combination with the P, S and E buttons, the button will turn yellow then to indicate selection. It is then possible to edit the eight value sliders without the sequencer running away from it.

The edit buttons ('copy E', 'copy S', 'copy P', 'clr E', 'clr S' and 'clr P') are functional. They will copy or clear Elements, Sections or Parts.

'copy E' will copy the previous Element to the selected one, when the selected Element is 1 nothing will be copied. 'clr E' will set the eight sliders for that element to zero.

'Copy S' will copy the previous Section to the selected one, when the selected Section is 1 nothing will be copied. 'clr S' will clear all values in the current Section (that is eight times eight values).

'copy P' will copy the previous Part to the selected one, when the selected Part is 1 nothing will be copied. 'clr P' will clear all values in the current Part (that is eight times eight times eight values).

Clicking once an E, S, or P button will select the associated Element, Section or Part (yellow). Clicking again will make the the button red, meaning it will be skipped on playback. Clicking yet another ttime will make it blue. Making a button red does not clear any values. A blue button acts as a reset point, and making a button blue does not clear anything either.

Selected E, S, or P buttons are yellow. Unselected, non skipped and non reset ones will be gray. So you know that when you see any yellow E, S or P buttons the sequencer is in 'Edit' mode.

The 'res' button also works to reset the sequencer in 'edit' mode.

Sequences can be saved to disk and reloaded just as any module can - as a preset. Right click on the module and select load / save preset from the context menu.

ModGateSeq

Modulated gate sequencer

version 1

polyphonic

[this module is RateSmart [1]]

A modulated gate sequencer.

Each step has three modes, it can be off (blank) it can be a trigger step (o) active for half a clock period or it can be in gate mode (O) staying active a full clock period.

The mdulation inputs control wheter a step will sound or not. A modulation input value <= 0 will make the step silent and a value > 0 will make the step perform according to how the button was set. Unconnected modulation inputs are set to 1, so they will produce active steps.

The rnd button will set a random pattern.

The clr button will clear all steps.

Steps that are turned off trough the modulation inputs wil flash orange instead of yellow.

The res input is a synced reset, it will only reset when the signal is active on a low to high transition of the trigger input.

The a-res input is an unsynced reset, it will always reset the module when the signal goes from low to high.

GenePlayer

Gen player

version 1

monophonic

[this module is RateSmart [1]]

A Nucleic Acid Sequence player module

This module scans text files for A, C, G and T (or U) characters (case insensitive) and builds a sequence from those with the letters mapped to the numbers 0, 1, 2 and 3 (such that A and T (U) are complemental, as are C and G). U is treated as if it were T.

Additionally W, S, M, K, R, Y, B, D, H, V and N are recognized, these are (according to their rules) randomly translated in one of A, C, G or T. W into A or T; S into C or G; M into A or C; K into G or T; R into A or G; Y into C or T; B into C, G or T; D into A, G or T; H into A, C or T; V into A, C or G; N into A, C, G or T.

All other letters (including Z, white space and numerals) will be skipped.

On playback the letters can be chained into groups of size 1 to 7 (3 would be the central dogma, codons encoding for amino acids (of which some may not exist for random letter sequences, but this module will assume existing sequences)). For a single letter there are four values [0.0, 0.25, 0.5, 0.75] or [0,0, 0,33, 0.67, 1.0] on the scaled output; for a group of two the values woud be [0.0, 0.125, 0.25. 0.375, 0.5. 0.625, 0.75, 0.875] (or their scaled equivalents).

On each trig the next group will be output, when the unit is in repeat mode it will jump back to the start when everything was played and when it is in once mode it will stop at the end.

The res input will reset the sequence to the beginning.

The changed output will fire when a value change on the output was seen.

The leftmost outputs are complement outputs, for ease of implementation just 1.0 - output.

A multi gate sequencer.

Each step has three modes, it can be off (blank) it can be a trigger step (o) active for half a clock period or it can be in gate mode (O) staying active a full clock period.

The rnd button will set a series or randomly selected Euclidean patterns depending on the selected length (which is assumed to be the maximum length under length modulation). The random selection will be all trigs or silence, gate mode will never be selected, but this can be changed manually as needed.

The clr button will clear all steps.

The select input selects the row to play

The number of steps can be modulated.

The res input is a synced reset, it will only reset when the signal is active on a low to high transition of the trigger input.

The a-res input is an unsynced reset, it will always reset the module when the signal goes from low to high.

282 Poetry

Page: Gen1 [type 327]

Poetry

' Poetry' generator

version 1

polyphonic

[this module is RateSmart [1]]

A 'Poetry' generator.

This module was modeled after the Poetry Generation Algorithm by Johnathan Mackenzie from his thesis 'Using Strange Attractors To Model Sound'.

The basic working is as follows:

A 'text' is assumed to be present in memory from which an arbitrary part is being selected as a seed. For each new output value to be generated the seed is found in the text and the value following the seed is the new value to be shifted into thee seed from the right side. The first value in the seed is being used as the current output.

The Text can be appended to by triggering the 'new input' input, and a new output value is obtained by triggering the 'new output' input.

When the text gets longer than the maximum set length the oldest value in the text will drop out and the new value will be appended. A text initially will have zero value only.

The seed will always be a sequence present in the text, whenever a new value is added to the text a new random seed will be calculated and whenever an output value is being requested the seed will be left shifted (and the leftmost value will drop out).

The seed length can be set longer than the history size, this will result in the history being played as is.

The Clr input is a latching input. A low to high transition will be remembered and then when a new value is clocked in a zero will be clocked in instead of the new value. After that the clr state will be reset to off. An active Clr status overrides the mode settings, so that when mode is set to unique a zero vaalue will still be clocked in when Clr had been active. Note that reset will not clear any stored values.

283 Arpeggiator

Page: Gen1 [type 349]

Arpeggiator

Arpeggiator

version 1

polyphonic

[this module is RateSmart [1]]

A simple arpeggiator

On each clock on the 'new in' input a new input sample is is taken and added to a list of samples, the oldest value present will be dropped from the list then.

This list can be left unsorted, it can be randomized or be set to play the lowest or highest note first .

The list length is set with the length control.

On each output clock on the 'new out' input the next stored value from the sorted list will be output.

In random mode the order in the sorted list will be randomized when the playout wraps back to the first value.

In unsorted mode the playout will be the recording order.

On the input side an acceptance filter can be applied. All incoming values can be accepted, values differing from the previous value or values not present yet in the list of samples.

The toggle input when inactive causes the selected sort order to be in effect and when active the next sort order will be used. This can be used to toggle between low to high and high to low modes, for instance.

When there are not enough input values available (yet) arbitrary values will be clocked out until the playout counter wraps back to zero.

The reset input (or a global reset) will cause the playout pointer to be set back to zero without changing any stored values.

The Clr input is a latching input. A low to high transition will be remembered and then when a new value is clocked in a zero will be clocked in instead of the new value. After that the clr state will be reset to off. An active Clr status overrides the mode settings, so that when mode is set to unique a zero vaalue will still be clocked in when Clr had been active. Note that reset will not clear any stored values.

Thr trans(parant) input cause the module to stop arpeggiting, instead it will on every outclock output the last value clocked in, making it into a sort of a sample and hold mode.

284 Markov

Page: Gen1 [type 350]

Markov

Markov chain

version 1

monophonic

A markov chain module.

This is a first order implementation.

The internal state consists of a number of nodes each holding some value (for which a maximum must be set with the max size control), a State variable holding the current node index (which is not under direct user control) and a matrix of transition chances (which is not under direct user control).

When the learn input goes active the current input value is looked up in the nodes, and when found the transition probability from the previous input value to this new one will be increased with the current strength value (which can be negative). When the new value wsa not found it will first be appended to the node list. When the node list becomes full and the mode is set to once an overflow condition occurss and the new value will not be learned (also the Ovfl light will go on then). When the mode is set to 'cont' no oveflow will occur but the oldest values will be discarded instead.

When the 'new ouput' input goes active the current State variable will move to a new one, this is a random process controlled by the transition chance matrix.

When clear goes active all internal state is discarded.

When the state space gets full the full light will indicate this and the full output will go active as well. Connecting the full output to the clear input will cause the internal state to b cleared when the state space gets full.

To make the module leaky you can set the max size to a lowish value, the strength to just above zero and then modulate the strength with a random value. A low max size will let new events come in at the cost of loosing older ones.

285 Rewriter

Page: Gen1 [type 1218]

Rewriter

A rule rewriter

version 1

polyphonic

[this module is RateSmart [1]]

A pattern rewrite module.

A couple of rewrite rules can be specified, and a maximum expansion level can be set.

There is a small alphabet of the letters A, B, C, D and E. For each letter a substitution is specified in terms of other letters. For instance:

  • A -> ABC
  • B -> C
  • C -> D
  • D -> AC
  • E -> B

Then a number of expansion steps is specified resulting in patterns to be generated. With the rules above those woud become (the numbers indicating the expansion level):

  • 0 : A
  • 1 : ABC
  • 2 : ABCCDEDEACB
  • 3 : ABCCDEDEACBACBABCDEC

etc. The maximum depth to be set is 8, which would result in a pretty long pattern already with the rules above.

At each positive input step a next symbol from the active generated pattern is selected and the corresponding output will be made active. At the end of the pattern it will start again from the beginning.

Some rules (or all) can be left blank for simpler patterns. All letters must be from the set [A..E], everything else will be ignored for pattern generation.

This is after an idea found at RobotPlanet, which in turn references this article.

There is a small alphabet of the letters A ... H. For each letter a substitution is specified in terms of other letters. For instance:

  • A -> ABC

  • 1 : ABC
  • 2 : ABCCDEDEACB
  • 3 : ABCCDEDEACBACBABCDEC

etc. The maximum depth to be set is 8, which would result in a pretty long pattern already with the rules above.

At each positive input step a next symbol from the active generated pattern is selected and the corresponding knob will then send it's value to the output. At the end of the pattern it will start again from the beginning.

Some rules (or all) can be left blank for simpler patterns. All letters must be from the set [A..E], everything else will be ignored for pattern generation.

The common chain input is added to the output value always, and then there are eight indivuidula chain inputs that are added to the output only when the corresponding rule is active (with this the module can be used as a mutiplexer as well).

This is after an idea found at RobotPlanet, which in turn references this article.

This module generates a sequence of notes based on an input pattern. The input pattern is a comma separated string of integers.

This is after an idea by Robert Inventor as explained here.

The generated numbers will be limited to a range [-60, 67], then for output generation 60 will be added with the result being interpreted as a note number, which is then translated to a standard note signal (for controlling oscillator frequencies etc.). Which means that a 0 output from the sequence will translate into middle C, a -1 output to B, a 1 to C#, etc.

CellAut

A cellular automaton

version 1

monophonic

[this module is RateSmart [1]]

A cellular atomaton.

This module implements an 'elementary cellular automaton'. Each cell can have a value of either zero or one. Three cells are evaluated according to the set rule and this will yield a new value for a next generation cell. The rule number [0 .. 255] is being interpreted as a bit pattern which is indexed by the three bit pattern generated from the three evaluated cells. This is all according to Wolfram's theory about elementary cellular automata. The start state of the automaton consists of one single cell having a value of one.

With the steps parameter you can set the number generations to be calculated, this results in a bit string. On every step a next bit will be sent to the output and when the end of the string is reached the sequence will wrap back to the beginning.

The Faults parameter sets the average number of cell faults generated for each new cell calculated. The set number is divided by 10,000.

The total length of the generated pattern increases with two on each new evaluated step, which results in length = 2 * steps + 1, which is odd always. The reset input can be used to wrap back sooner.

Some rules will not generate any output at all (like rule 0 or 255), some will generate simple repeating patterns and others willl be almost random. For some rules the steps setting may not change the sequence much, for others a next step may differ wildly from the previous one.

The blue output has a weighted sum of the last three bits ( Bit[ anIndex] + ( Bit[ anIndex - 1] shl 1) + ( Bit[ anIndex - 2] shl 2)) / 8.0. The dir input when active reverses the play direction.

For some ideas about possibly interesting rules have a look at my rules page. At some stage I may build some of the visulas into Wren, but not at this stage. That page, at the very end, also shows an implementation of the algorithm being used.

LifeSeq

Life sequencer

version 1

monophonic

[this module is RateSmart [1]]

A Life based sequencer.

This module can also be used as a 32 x 32 sequencer, provided the mode is set to 'Freeze'.

Based on Conway's game of Life, but there are some extra modes selectable from the mode selector, one of them being the 'Freeze' mode, which stops all cellular engine activities (but the cursor functions still work, turning he module into a sequencer).

The step input moves the cursor, which will put the cell values from the curent column on the green outputs.

The change input triggers a new generation of live cells, according to the currently selected rule, the change input does have an inhibit function to freeze the current pattern.

The blue sum output outputs a function based on the values under the cursor. The modes are :

  • bin - a binary sum of the active cells, scaled to the range [0 .. 1]
  • lin - the count of of the active cells, scaled to the range [0 .. 1]
  • max - the index of the highest active cell, scaled to the range [0 .. 1]
  • min - the index of the lowest active cell, scaled to the range [0 .. 1]
  • avg - the average index of the active cells, scaled to the range [0 .. 1]
  • note - as lin, translated to a note value, range is [0 .. 31]
  • maxn - as max, translated to a note value, range is [0 .. 31]
  • minn - as min, translated to a note value, range is [0 .. 31]
  • avgn - as avg, translated to a note value, range is [0 .. 31]

The grid can be set to be wrapped or unwrapped. In wrapped mode the top connects to the bottom and the left side to the right, and topologically it is equal to a torus then.

The fault rate parameter determines the amount of faults made in applying the evolution rule, set to a low value it can get stuck patterns going again after a while.

When the number of cells drops below the low count the grid will be filled with random values, the chance of a cell becoming alive then is set with the rnd amt parameter. This will bring back some life when all cells ended up being dead.

The rnd button will fill the grid with a random patttern, obeying the rnd amt setting.

The clr button will clear the grid, this usually will then immediatly set random pattern as the live cell count drops below the minimum. It is of use in the Freeze mode to quickly erase a mouse painting that did not turn out as it should.

It is possible to draw on the grid. A single click will toggle the cell state, with shift cells can be turned on and using ctrl instead will turn cells off.

Using a right click on the grid the current state can be saved to or loaded from a file. Best to be used in the Freeze mode only.

The xstep input moves the cursor in the x direction, which will put the cell values from the curent column on the horizontal green outputs.

The ystep input moves the cursor in the y direction, which will put the cell values from the curent row on the vertical green outputs.

The change input triggers a new generation of live cells, according to the currently selected rule.

The blue outputs output column and row sums, they output the count of live cells for each column or row.

The diagonal outputs, gree and blue, output the sum of the green and blue output row and column.

The grid can be set to be wrapped or unwrapped. In wrapped mode the top connects to the bottom and the left side to the right, and topologically this is equal to a torus.

Life sequencer inspired by PHOBoS

version 1

monophonic

[this module is RateSmart [1]]

A Life based sequencer based on ideas posted by PHOBoS on the electro-music.com forum.

Based on Conway's game of Life, but there are some extra modes selectable from the mode selector, one of them being the 'Freeze' mode, which stops all cellular engine activities (but the cursor and input functions still work, turning he module into a sequencer (presumably not clocking in new data in that case)).

The clock input clocks the current input value into the module. It will be quantized to a note number and that will determine a cell to be turned alive.

The step input moves the cursor, X first and when X wraps Y moves. When the cursor lands on a live cell the note associated with it will be sent to the output. The rev input will reverse the scan direction. When the X or Y input are connected however the behaviour will change a bit. In this case the X and Y inputs will directly set the grid cursor, and the rev input will not have any effect anymore. When the step input is not connected but one or two of the X and Y inputs are the X and Y inputs act asynchroneously, that is: no steps are needed to make them work.

The change input triggers a new generation of live cells, according to the currently selected rule.

The grid can be set (and is so by default) to be wrapped or unwrapped. In wrapped mode the top connects to the bottom and the left side to the right, and topologically it is equal to a torus then.

The fault rate parameter determines the amount of faults made in applying the evolution rule, set to a low value it can get stuck patterns going again after a while.

[this module is RateSmart [1]]

A MUSE like melody generator.

This implementation more or less follows the schematics as publushed by PHOBoS at http://electro-music.com/forum/viewtopic.php?p=430620

The oscillator was left out, instead the output has a control signal with values 0/32 to 31/32.

The external inputs go to the switches directly.

The switch positions can be modulated. There are 44 positions, the first position is off and all modulations resulting in a value > 43 will be translated to off as well.

The co 0 and co 31 outputs are the left and right carry out signals, the left out going active on lefft shifts only and the other one for right shifts only. Thes outputs can be used for chaing AMuse modules.

The inv output outputs 1 - out, so values from 32/32 down to 1/32.

The rev input when active reverses the direction of the shift register, when reversed the bit output will output bit 0 and the parity info is input at the high side of the shift register. The taps will stay at the same position.

With the parity controls the parity generator can be switched between odd and even.

The free / clocked control selects between some changes taking place immediately or or synced to the trig input, this affects the res input and modulation applied to the switches. The parity, rev and ext inputs will always be synced.

The idea is to have a swan and a couple of hunters chasing it. The swan can fly so it's on an arbitrary position (but within the bounding box of the paths). The hunters though must walk on the paths. The paths themseleves are created by a turtle, for which I made a forth like system to implement turtle graphics.

This module needs a forth specification file in order for it to work. It will search for mazes.4th in the application directory. This file defines a couple of exports, which are forth words marked with an export directive, they must not consume nor return any stack entries.

The hunters will close in on the swan on every clock pulse they receive, using the path having the (local) shortest distance to it, with the twist that no two hunters can be in the same location (when enabled with the 'dups ok' / 'no dups' selector). The swan can be moved by appying signals to the swan X and y inputs.

The output values are taken from the last angle a hunter made and the last distance it traveled.

For inputs and outputs the signal type to be used can be selected.

There is a test tool available for debugging mazes.4th, this is the SwanTest.exe application (to be added to the release package).

Economy

Wealth distribution simulation

version 1

monophonic

[this module is RateSmart [1]]

A wealth distribution simulator.

The simulator has a population of 1001 members. Initially all members start off with the same wealth of 0.1. As the total wealth over the sumulation is held constant this initial wealth is also the average wealth.

On each iteration two members are drawn at random and they will trade for an amount that ranges from 0% to 5% of the wealth of the poorest of the two. The direction of the trade is selected at random.

Each trade is being taxed, and the tax flows from the richest to the poorest party in that trade.

This way the wealth of the members in the population will change.

  • chi - Tax, transfers wealth from those above mean to those below mean wealth
  • kappa - Negative wealth- or depth-control.

The clock (output clock) sets a new output value, the model itself is updated on every on every system- or control-rate clock (depending on wheter the module runs fast or slow).

Output values are determind by the current wealth of a randomly selected memeber. This makes the module basically a random generator.

The default values for chi, zeta and kappa model the USA economy.

DPendulum

Double pendulum simulation

version 1

polyphonic

[this module is RateSmart [1]]

A double pendulum simulation.

This module can either be free running or clocked, it will be clocked when something gets connected to the clk input.

The m1 / m2 control sets the mass ratio between the masses at the ends of the pendulum arms. The sum of the masses is set fixed to 20 kg.

The l1 / l2 control sets the length ratio between the lengths of the pendulum arms, the sum of the lengths is set fixed to 20m.

The speed control and it's modulation input set the simulation step size, the simulation will not proceed when the speed is zero. For negative speeds the simulation will run in opposite direction (but gravity stays as it is).

For large speeds the precission of the simulation will diminish and somewhat longer runs may result in non-chaotic behaviour.

The reset input or button can bring the module back to it's starting state.

With the G mod. input gravity can be changed, it cam be made negative too.

Oramics

version 1

[this module is RateSmart [1]]

Oramics 1

This module uses an image which it will divide into four tracks. For each track the graphical information will be transferred to the corresponding output.

The image can be larger than what is shown on the module, it will be scaled to fit the display. For playback the actual image data will be used, so the resulution can be higher than the screen resolution.

The image is treated as a sort of a graphical score, and it is played in the vertical direction as controlled by the position input.

The image is read at the position of the horizontal cursor line.

There are a couple of modes for the way image data will be handled, all modes are monochrome - red, green and blue information will simly be added.

1) Weight : for each column and each line in the column the summed value determines the output.

2) Center: the center of mass is calculated for each line in each column, the value is sent to the output.

3) PkVal: or peak value, the value of the brightest spot in each line is for each column sent to the output.

4) PkPos: or peak position, the position of the strongest light in each line is for every column sent to the associated output.

Then there are two modifiers, one for selecting the type od the position signal and another for setting the types for all outputs (individuallhy).

A file change detector

version 1

monophonic

Notes about polyphony: The text and detection is shared over all voices.

A file line change detector

When a change in the last line of a fie is being detected the ouput will go active briefly.

This module should use input from a file by typing :

file:fillename

or

file:fillename regular-expression

The last non-empty line of the file will be read (or an error message will be returned) and that line will be filtered with the optional regular expression.

When the regular expression contains a group named 'result' that will be the matched bit from that last line.

Example:

X:\filedir\filename.log (?:msg\s\[)(?<result>.*?)(?:\]\shost)

pointing to some file on drive X: with a specified filter which has a group named
'result' (and two other unnmaed groups of stuff we are not interested in).

the last non empty line of the specified file could be (this is from a log of an IRC
chat session, a priviat message from jan to group #electro):

  '2022-02-09 01:30:23.784 | priv : [jan -> #electro] msg [pwew .. filter is hard o_o] host [~jan@xxx-xx-xxx-xxx.yyy.zzz.nl]'

The regular expression   matches:  'msg [pwew .. filter is hard o_o] host'.
The named group 'result' matches:  'pwew .. filter is hard o_o'
and that in this case is the bit we want.

305 Convolver

Convolver

A convolution (reverb) processor

version 1

monophonic

Notes about polyphony: The module is mono-, the am input poly-phonic.

A convolution (reverb) processor.

This module outputs the convolution of it's input signal(s) with a loaded wave file.

When the file is mono the sum of the left and right inputs is being convolved with that mono signal and the left and right outputs will have the same signal. The right side convolution will not be processed in that case.

When there are two or more channels in the wave, the first two fill be used, channel 1 for the left side and channel 2 for the right side. Both convolutions will be processed in this case.

When there is no valid file loaded, or the number of channels is zero for some reason, the outputs will be a copy of the inputs.

When the loaded file is an impulse response (of a room or a violin body for instance) the module will act as a reverb with the characteristics of that room (violin body).

The module does no sample rate conversion on the impulse file.

308 Compressor

Page: FX [type 906]

Compressor

Level Compressor / AGC

version 3

monophonic

A simple feedback based compressor.

The compressor tries to maintain the set reference level as the output peak or RMS value,

To do so it can reduce it's internal gain as much as needed, or it can add gain to a maximum of the set gain. When the gain is set higher the knee will become more pronounced as well.

The response times can be set with the A (Attack) and R (Release) controls. In RMS mode the Attack control also controls the RMS averaging time.

A DC blocker was implemented for the control chain, the signal path itself is not DC blocked. The cuttoff frequency for the DC blocker is approximately 20 ~ 40 Hz (depending on sample rate).

When side chaining is selected the compression will be calculated based on the side signal, and the calculated amplification still is applied to the input signals then. The side signal is treated internally in the same way as the signal chains are. The compessed side chain vaalue is available as a separate output.

There also is another way to do side chaining, as the internal amplification factor is also available as an output. This is the env output, and it can be used with a multiplier to apply the compression to some other signal.

324 TropicalMixer

Page: FX [type 384]

TropicalMixer

Tropical mixer

version 1

polyphonic

[this module is RateSmart [1]]

A Tropical Mixer module.

What it does is mathematically simple … it computes the minimum and maximum of some values. The values are made from an input value summed with a constant value and a modulation input.

This is an idea obtained from the Tropical Mixer module as implemented in GleetchLab, which seems to have got it's idea from Nozoid's Tropical Additive Synthesis, which then in turn is based on Tropical Algebra. Basically that is equivalent to what is also called an Analog And function where values are being added to the inputs before the minimum is being calculated. In this case the values are slider positions, added to a modulation input (which have a value of 0.0 when nothing is connected to them). In addition to the minimum value (tropical) the maximum value (polar) is being calculated as well (as this module is an expansion of the AnalogAndOr module).

To make it do Tropical Additive Synhesis you can use a sine oscillator followed by a ChebGen (wave rate multiplier) module, feeding the outputs of the oscillator and the ChebGen into the ins of this module, and then fiddle with the sliders and modulations.

With the AC/DC switch AC blocking on the output signals can be turned on or off.

The mode can be either tropical or sub-tropical, tropical being the min/max of the sums and sub-tropical being the min/max of the products. When the mode is sub-tropical the mods inputs will default to 1.0 and in the tropical mode to 0.0.

All ins support the special NOT_CONNECTED status, the mods do not.

There is some record control through the rec / off control and when recording is off the delay line signal is being looped. When it is on the input left of it morphs between recording and recycling.

Inter ons. controls the time between grain starts. Duration controls the length of a grain, vol the amplitude and pan the stereo panning.

The grain playback speed is set trough the grain speed input, this input will clip at 0.0001 (where a grain would be slowed down by a factor of 10,000) on the low side, it is not being clipped on the high side.

Grain offset sets te offset of the grain in the sample buffer.

Once a grain is started all of it's parameters are set, and they do not change during the grain's lifetime.

The modulations for this module are random based; the interonset, duration, volume and pan are chosen randomly with an amount as set by the modulation signals and controls. Otherwise it is the same as the Granulator module.

With the rnd smoothness controls you can set the amount of smoothing to be used on the random signals.

This module is delay line based. The input signal stored onto the delay line and the grains take their signal from it.

There is some record control through the rec / off control and when recording is off the delay line signal is being looped. When it is on the input left of it morphs between recording and recycling.

Inter ons. controls the time between grain starts. Duration controls the length of a grain, vol the amplitude and pan the stereo panning.

The grain playback speed is set trough the grain speed input, this input will clip at 0.0001 (where a grain would be slowed down by a factor of 10,000) on the low side, it is not being clipped on the high side.

Grain offset sets the startpoint of th egrain in the delay line.

Once a grain is started all of it's parameters are set, and they do not change during the grain's lifetime.

339 GrainDelay

Page: Delay [type 719]

GrainDelay

Grained delay

version 1

polyphonic

A graining delay module.

This module is based on a delay line. The number of grains can be set from 1 to 4 and these are repeating grains. The repeat rate is being set by the frequency controls.

When there is more than one grain the grains will overlap due to pahse shift to them being set. The pahse shift is one divided by the grain duration - this will cause the envelopes to overlap (in the case of two grains and a bell envolope set to maximum duration this will mean that the effective envelope will be flat).

When a new particle starts the control inputs will be sampled to determine how that specific particle will behave, and once set this will not change during the particle's life time.

Different envelope types can be selected.

The length of the delay line can be set from 10 micro seconds to 5 minutes, in three ranges (output generation may be delayed quite a bit for long delay settings).

Each particle has:

  • A repeat rate as set by the frequency controls.
  • A post grain delay which determines a wait time after the grain was played. This is determined by the DC parameters. The cycle time will not change by this.
  • A pan position, determining it's stereo positioning.
  • An amplitude as set by the am controls.
  • A playback speed determined by the speed (spd) controls.

The module has a dly output which will privide the set delay time on the input signal - it can be used for looping with some extra modules added.

ClockedDelay16

16 out clocked delay

version 1

polyphonic

[this module is RateSmart [1]]

A 16 stage clocked delay, or an analog shift register.

In clocked mode on each up going clock out15 will get the out14 value ... etc. and finally out0 will get the current input value.

In fast mode it does the same thing, but it ignores the input clock and instead it shifts on every 'execution clock' (which can be control rate or audio rate, depending on the connected signal speeds).

This module can be used as a digital shift register as well when a digital valued input signal is being used.

341 AllPass

Page: Delay [type 713]

AllPass

All pass filter

version 1

polyphonic

An all-pass filter.

An all pass filter passes all frequencies with zero attenuation, but it will change the signal phase in a frequency dependent way.

The delay length can be set with with the length parameter. This is in samples, and so the actual time will depend on the current sample rate.

The feedback factor fb is used to trim the frequency at which the the phase shift is halfway. The factor fb can be modulated but the resulting value always has to be in the range [-1,1].

The LEDs indicates internal clipping of the modulation signal, e.g. it is going outside the range [-1,1].

This unit can be used for several purposes. The phase smearing can be used to reduce peak amplitudes for impulse like signals, helping to avoid clipping. When k is being modulated there will be a phase distortion varying with time, resulting in signal warble or in FM like effects for higher modulation rates and longer lengths.

TapeRecorder

Patch audio output

version 1

polyphonic

Notes about polyphony: Voices are summed before recording, only the delay modulation is polyphonic.

Recorder

A 1 to 8 channel audo recorder that can write it's recording to a wave file on disk.

The tape length can be set from 1 to 30 minutes and when the tape is full recording will continue writing over old material.

The record control starts or stops recording, the write control starts a disk write (for which a file has to be selected before) and the clear control will erase the tape.

Write, clear and record can be controlled by the buttons as well as by logic input signals.

The record output is active when recording is OFF, such that when it is connected to the clear and write inputs the wave gets saved and cleared when recording is stopped.

The full output goes active when the tape loop is fully recorded, such that when connected to the clear and write inputs the wave gets saved when the loop is full.

The eight audio outputs will output the input signal with a delay time set by the delay controls and the delay modulation input, as if it were a tape montoring signal.

In the file name %patchname% can be used, this will be replaced by the name of the patch. When you patch is C:\wren\patches\silly-putty.wren the patch name will be silly-putty, then when you set the file name to save the wave to as C:\wren\recordings\cc-%patchname%.wav the wave data will be written to the file C:\wren\recordings\cc-silly-putty.wav.

When 'time stamped' is being selected the file name will be prefixed by a time stamp.

When 'normalized' is selected the wave data will be normalized before it is being written out to the file.

When the file name is clear, the box will show 'Ctrl click to select a file' in that case data will not be written to disk at all, in this case the module can be used as an 8 channel delay module with modulatable delay time (for instance to make eight channel flanging).

Note that when record is not active the eight ouputs will not have any signal.

PluckControl

Pluck controller

version 1

polyphonic

Pluck controller.

This module processes an excitation signal to be used for the Pluck and KS (Karplus-Strong) modules.

It works by sending the input signal trough a tuned comb filter.

The shift controls manipulate the point where the Pluck signal will be struck by the excitation.

The Mix controls set the mixing between the input signal and the comb filtered version.

The color and Q controls manipulate a low-pass filter that is applied to the signal.

For it to work as intended the frequency knob and control input should have the same value as the connected Pluck or KS module.

The module can also be used as a stand alone comb filter with added coloration.

The coloration filter is a 12dB resonating low-pass filter.

The coloration filter is being applied before the comb filtering.

Notes about polyphony: The pos, speed and fm controls are polyphonic.

Tiny Speech Synth.

A very rudimentary phoneme speaker.

Phonemes are : a, b, d, e, E, f, g, h, i, j, k, l, m, n, o, p, r, s, S, t, T, u, v, w, z, Z.

WebRef: http://www.pouet.net/prod.php?which=50530

Original code was created by : Stepanov Andrey, 2008.

This module converts a phoneme sequence to an itnernal Wave representation which can then be played back under control of the pos speed and fm parameters.

This module follows the original code closely.

This module can use input from a file by typing :

file:fillename

or

file:fillename regular-expression

The last non-empty line of the file will be read (or an error message will be returned) and that line will be filtered with the optional regular expression.

When the regular expression contains a group named 'result' that will be the matched bit from that last line.

Example:

X:\filedir\filename.log (?:msg\s\[)(?<result>.*?)(?:\]\shost)

pointing to some file on drive X: with a specified filter which has a group named
'result' (and two other unnmaed groups of stuff we are not interested in).

the last non empty line of the specified file could be (this is from a log of an IRC
chat session, a priviat message from jan to group #electro):

  '2022-02-09 01:30:23.784 | priv : [jan -> #electro] msg [pwew .. filter is hard o_o] host [~jan@xxx-xx-xxx-xxx.yyy.zzz.nl]'

The regular expression   matches:  'msg [pwew .. filter is hard o_o] host'.
The named group 'result' matches:  'pwew .. filter is hard o_o'
and that in this case is the bit we want.

WebRef: http://www.pouet.net/prod.php?which=50530

Original code was created by : Stepanov Andrey, 2008.

This module adds some features to the Tiny Speech Synth. It has phase and frequency control on the glottal oscillator for which two wave forms can be selected, a saw shaped and a pulse shaped wave. The amount of noise (whisper) added can be controlled as well. There is speed control for the phoneme rate.

A couple of outputs are provided that send trigger pulses for text start, phoneme strt, silence start, vowel start. These can be used to control external modules (like sync pitch changes to vowel starts for instance). The text end output will go active when there are no phonemes left to be spoken.

There is a reset input, after reset the module will speak it's text once - unless it is set to loop.

The FI control (left of the frequency display) can be used to change the filter, in the FI position it is smoother on consonants.

This module can use input from a file by typing :

file:fillename

or

file:fillename regular-expression

The last non-empty line of the file will be read (or an error message will be returned) and that line will be filtered with the optional regular expression.

Notes about polyphony: The pos, speed and fm controls are polyphonic.

A SAPI based speech module.

This module uses the Windows Speech API, with the voices that happen to be installed for it. Additional voices can be installed for free, for example by installing eSpeak.

For older windows versions it may be necessary to download and install the SAPI development kit, look for the SAPI 5.1 one.

This module does not work in real-time, that is when changes are made to the text or the sample rate the speech will be compiled into wav format, and it is the resulting wav that can be manipulated in real-real time. Thos has some limots of course ...

It is possible to use some speech markup in the text, for instance <rate speed="-10"/> to make it speak slower, more about this can be found in the SAPI documentation.

This is a pretty bare bones module, with just a position, a speed and a frequency control input.

This module can use input from a file by typing :

file:fillename

or

eSpeakVoice

eSpeak Speech Synth

version 1

monophonic

An sSpeak based speech module.

This module uses the eSpeak voices (and not the windows voices) by using the espeak-sapi.dll. ESpeak must be installed for this to work and the espeak-sapi.dll must be findable trough the path environment variable (it can be put into the wren application folder).

This module more or less re-implements the song module, with better speech quality.

The module is non-real-time, on any text changes or on any parameter changes that would alter the speech generation new wave data is being compiled, it will keep the positions of speech events though. This also means that the module is somewhat slow when used with a lot of text.

This module has position, speed and frequency modulation inputs. A cents control is provided too (the eSpeak voices seem to be tuned pretty arbitrarlily).

Several outputs are present which signal silence, vowel, phoneme, word or sentence occurance. Also it is possible to put some special marks into the text {!} and {!<foat-value>} ({!-.123}) for instance. Values will be output on the user output, and all mark types will generate a short pulse on the mark output.

This module can use input from a file by typing :

file:fillename

An oscilloscope.

The module listens to the selected voice only.

The input signal is amplified by the level control.

The time base can be set to various values, the values reflect the time for the full screen width (so not the usual time per division). For long time base values the update frequeency is low. The shortest time span that can be set is one point per sample, in this position the relation between signal rate and size on screen depends on the sample rate.

Trigger mode can be set Level and Ext. In Level mode the trig level sets the level to be used for triggering and the input signal (before attenuation/amplification) is used for that. In Ext. mode the ext. tr. input is being used, this is a digital input and the trigger level controls do not affect triggering on this input. Either an upgoing or a downgoing signal edge can be used to trigger on.

The input can be AC or DC coupled, the default mode is DC.

374 Tapper

Page: Utility [type 1113]

Tapper

Tap rate detector

version 1

polyphonic

A tap rate detector.

The control output can be used some different kind of controls. It can either control an LFO which is set to fast 0.254, medium 2:05 or BPM mode; a Delay set to 3s or 5 min, or it can control the ClockGen module's BPM value.

The green tap input can be used to auto-tap the module from an LFO or from a ClockGen module.

The rate multiplier controls the scaling applied to the control output, it will make controlled LFOs go faster or slower by some factor.

The sync output is activated for 1 ms on each tap action and on each cycle, it can be used to sync an LFO (when the rate multiplier is set to a / mode (less than 1) an extra divider will be needed to not prematurely reset the LFO).

The sync output can also be mannually triggered with the sync button.

The slave in and output can be used to chain up several MidiClockIn, RateConverter or Tapper modules, the first one in the chain will be the master controlling all other Tappers. Other tappers can be set to different control modes to get LFOs and delays synced up properly at different rates.

The P, X and slave inputs are polyphonic, and so is the control output. The tap input listens on the first voice only, the sync output fires on all voices simultaneously and the slave output is identical over all voices too.

375 TextWriter

TextWriter

Patch comment written to file

version 1

monophonic

Notes about polyphony: This module listens on the first voice only.

This module can write text to a text file. Each time the trig input goes active the next text line is sent to a selected file. I'm using it to update stream titles from, say, a poem.

The file will also be written on patch reset or when the patch is loaded into the patch editor. When no trigger signals are generated the first line of text will be used as a static text.

Note: writing to file will not work when the module is nested into a sub-patch (Abstraction module).

376 DataRecorder

DataRecorder

Data recorder

version 1

polyphonic

Notes about polyphony: This module works on the selected voice only.

Data Recorder

An 8 channel data recorder that can write it's recording to a csv file on disk.

The recording duration can be set from 1 to 5 minutes and when the memory is full recording will continue writing over old material.

The record control starts or stops recording, the write control starts a disk write (for which a file has to be selected before) and the clear control will erase all data.

Write, clear and record can be controlled by the buttons as well as by logic input signals.

The rec on ouput is active when recording is on.

The rec off output is active when recording is OFF, such that when it is connected to the clear and write inputs the wave gets saved and cleared when recording is stopped.

The full output goes active when the tape loop is fully recorded, such that when connected to the clear and write inputs the wave gets saved when the loop is full.

In the file name %patchname% can be used, this will be replaced by the name of the patch. When you patch is C:\wren\patches\silly-putty.wren the patch name will be silly-putty, then data will be written to the file C:\wren\recordings\cc-silly-putty.txt.

When 'time stamped' is being selected the file name will be prefixed by a time stamp.

When the file name is clear, the box will show 'Ctrl click to select a file' in that case data will not be written to disk at all, there will be no prompt for a file to save to.

CSV files can be played by the CsvData module.

377 Mambi

Mambi

mosc's ambiophonic processor

version 1

monophonic

Notes about polyphony: Strictly monophonic, the width modulation only works fronm the first voice; the inputs make a sum over all voices..

Mosc's ambiophonics module, or Mambi.

See https://electro-music.com/form/topic-27871.html for Mosc's original idea.

The delay maxes at about 320 us, the default delay setting of 0.25 makes the delay ab out 80us which is what the original uses. The delay length is interpolated with an all pass algorithm.

The width parameter can be modulated, the modulation input is 1.0 when unconnected and it will be multiplied with the knob set value once connected.

As the module is strictly monophonic, the width modulation only works on the first voice. The inputs are summed though over all voices and the ouputs are distributed over all voices.

The balance modulation is a mono signal too, the first voice is being used. In contrast to width modulation for balance the modulation is being added to, and not multiplied by, the balance knob setting.
