Wren

I think I got all the changes … but .. meanwhile I had been hospitalized for a day or two and quit smoking - so things are a tad hectic here lately :’) (but I seem to be able to concentrate a bit again)

The following changes I could find back in the paper trail (and made a source code release as well - but forgot to update the build numbers - oh well, too many version numbers) :

• Fixed cursor orientation for a couple of modules - it was a horizontal line where it was supposed to be a vertical one.
• Added better DLL presence checks.
• Upped the FFTW max threads from 1 to 4.
• Added envelope ranges to SimpleRange and RangeConverter modules - to make envelope time modulation easier.
• Patch version was upped from 13 to 14 for the above change the be handled correctly.
• The Convolver module works now, with not too much latency in the convolutions (using FFT based overlapped convolution). Reverb times of minutes are possible - or use it for special FX.
• The OSC Sync module will now pass one float parameter - it used to pass the syhnc only. The param could be used to transfer tuning or speed to another Wren instance.
• Changed the way the default folders work - for an existing file it will use the folder from the file name now instead of always using the preset / predefined folder.
• Made a patch player for which a set of patches to be played and a volume curve can be specified. Patches can not be played overlapped but sequenctioa only - when overlap is need two Wren’s can be executed in parallel.
• Fixed a bug in the spectrum module.
• Changed the way that FFT normalization is processed and fixed all FFT based modules for this.
• Made an Easing module - to be driven from some linear signal it can make several kinds of curves both control and audio rate.
• Made optional automatic sample rate conversion for wave files, this requires r8bsrc.dll to be present - it is in the latest release but not in the pre-release. When the dll is not present conversion will just not work. Also made optional sample level normalization.

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). For the sample rate conversion to work you’ll want to install the full version.

For the Easing module: With the pos input the the lookup position is being changed and the looked up value will be on the out ouput (possibly multiplied by a connected gain). The inv output holds 1.0 minus out and the rightmost sigin sigout link is being modulated by the out signal. Signal types are selected by the triangle buttons.

For the patch player: One can set a list of patches, and for each patch a volume curve is defined. Patch playing is sequential - there is no overlap. When overlap is wanted the idea is to start a second Wren instance for filling up the silent bits.

This was used with two Wrens for the ‘I read it al wrong’ performance mentioned a few posts ago.
