Wren

Saturday September 24 will be another electro-music.com >> live << concert.

See the electro-music.com event site for more info.

I’ll be doing one hour of pure Wren stuff on that occasion, titled “Flights of Angels”.

A recording can be found at the event’s forum page.

Saturday June 25 there will be another electro-music.com >> live << concert.

See the electro-music.com event site for more info, and also see the schedule (still under construction as when I wrote this but not likely to be changed).

Deo volente … I’ll be doing one hour of pure Wren stuff on that occasion, titled “I Read It All Wrong” - and my thanks go out to Thomas for the title.

The poster has some of the patch names to be used, I’m planning to make some more this week.

“Anno Un Cement” might have been a nice title :’)

And yes - 🔥 - is a title too!

Updated the example patches to have all my patches up to the date of this posting.

I’ll have the wiki to have the official link .. so eh .. there’d be just one place to change when the location changes - if not forgotten :’)

The latest patches require Wren version 2022.6.4.0 - see previous two or three posts.

Published as pre-release and release version 2022.6.2.0

This can be installed from a recent Wren version - or alternatively download the installer (see the wiki for more info on updating or installing Wren).

• Redid the Pluck module, got out the inversion stuff but gave it an extra string with detuning and cross coupling - I think it to sound more interesting.
• Made a PluckControl module - I see that the help for it is nonsense still - but it is meant to create a pluck signal for the Pluck and KS modules..
• Fixed the tuned delay module - it’s delay times were wrong.
• Fixed the PhaseDetector module - it never worked since Wren got polyphonic.
• Another 2000 lines or so of code were removed.
• Totally redid signal propagation, the way how signals are transferred over wires. It made Wren faster by another five to ten percent.
• Fixed a bug in the compressor module - unfortunately old patches will have wrong compressor gain now and need to be reviewed (they'’l be pretty soft now).
• Sped up the handling of the lights a bit more, there was some unneeded searching still for screen elements.

There were a lot of changes made to the code and I tested a lot but not everything - there may be surprises .. and when I notice I’ll fix things.

A recording of the pluck stuff - and some more sounds.

It starts with some Karplus-Strong sounds only; a drum like sound and a more typical KS one. At about one minute percussive noise is added, at about two minutes some grain processing is turned on and at around three the PADSynth module is activated.

It is a three voice self playing patch running at 48kHz with a control decimation of 32 needing about 30% of ome core here.

Some details (including a short help for the pluck controller and also about the patch) are behind the read more link.

Klaus Schulze’s music was one of the reasons, decades ago, for me wanting to do things with synthesizers - may he float on eternal waves; I’m glad he pressed record so often!

Here is a little patch I did after re-listening some of his work. It also demonstrates the use of the latest two new modules and the analog trigger mode of the envelopes - as I happened to be working on those things when the news reached me.

download the patch - it needs Wren version 2022-.5.2.0 or later (see previous post).

A couple more changes on the DataGraph and ClockGen2 module, such that they work better for me.

I’ve relabeld a couple of signals; sync is now quantise as that is what it actually does; the rate is now labeled as bars / m (bars per minute) and the div rate is now accents.

here is a new bars control added for the ClockGen2 module - this is the number of divisions to be used in the DataGraph and this can be automated by pulling a wire from ClockGen2’s new bars out to the new horizontal divisions input of the DataGraph (left of the 16 in the image).

For the DataGraph moduele the way divisons work changed a bit - it is now possible to have uneven divisions (existing patches may want to double their division settings, this also applies to the AudoGraph module). No middle indication will be drawn whe nthe number of divisions is odd.

The image shows how to work with this, both time and pitch are quantised this way without the need for precicise dot placement in the DataGraph.

Made an example patch for this, it is to be seen seen, heard and downloaded from below (possibly after clicking ‘Read more…’).

Note: image shows the latest version of the module, click on read more below to see the old version.

Changed the graph colors a bit to make the new dots mode better visible. The dots mode basically is the same as the steps mode except there are no lines drawn between the dots. Then I made the lines (and dots) mode actually work - which they did not.

Also a chg (changed) output was added and a sync input.

NOTE: as of version 2022.1.28.0 the module has inbuilt stretch on the trig input, and no extra module is needed for pulse lengthening.

Made a new envelope module of sorts.

I had been experimenting before with a State Variable Filter (SVF) set to low frequencies as a method of getting some ressonance in the processed signal. Worked that out to use a time setting instead of a frequency setting for the filter and allowing for very long times (ultra low frequencies … like once per hour) and for pretty short times like 500µs (2kHz - in the audio range).

There are some details and an example patch (including a short mp3 recording from it) in the more section.

Some relatively simple audio demos, and patches they were made with. These are all from self playing patches (noodles).
