23volts 1.0 release

Hello there,

I’m glad to announce my first contribution and the arrival of the 23volts module family to the wonderful land of VCVRack.

  • Cells is a deterministic gate sequencer based on Conway’s game of life algorithm.

  • ClockM8 is a polyphonic, quantized, clock modulator designed for extreme clock modulation.

  • Morph is an XY controller which can morph between 4 different snapshots.

  • Mem is a Sample&Hold module with internal memory up to 16K samples.

  • Merge8 is an 8 channel polyphonic merger.

  • Split8 is an 8 channel polyphonic splitter.

  • SwitchN1 is a polyphonic N to 1 sequential switch.

It’s been a long ride, learning C++, SVG panel design and Rack API, which was made definitely enjoyable due to the amount of open source plugins there on github (I won’t give any names because my VCV-Examples folder is quite large… but guys, you know who you are… thank you!! :slight_smile: )

The plugin will be available soon in the plugin manager. For those on osx, a compiled version is available there :

OSX Release

It requires VCV version 1.1.6 or above.

Don’t hesitate to report any issue here or on Github.

Have fun!

Very nice! Just wanted to code a polyphonic sequential switch, but you did it already. :slight_smile:

Build fails here on linux (building with rack 1.1.5):

src/Mem.cpp: In member function ‘virtual void Mem::dataFromJson(json_t*)’:
src/Mem.cpp:294:67: error: too few arguments to function ‘uint8_t* rack::string::fromBase64(const string&, size_t*)’
   std::vector<uint8_t> memoryVector = string::fromBase64(memoryStr);

It needs the 1.1.6 SDK as this method signature has changed since 1.1.5

Thought that might be the issue, hence mentioning 1.1.5.

@Vortico are there plans to incorporate module browser caching into the official release and if so when? Reluctant to move on from the modified 1.1.5 as the browser full screen on 4K is just too sluggish, my system though not new is not slow, others must suffer with it too.

Can someone provide a win build? I really would like to test these.

I didn’t test the modules thoroughly or anything, just confirmed they show up in the Rack 1.1.6 browser :


Nice! :slightly_smiling_face:
