Snowgrains is a Puredata synthesizer combining a subtractive monosynth with a granular synth. It currently runs on Critter & Guitari Organelle-M, but ports to run it on different hardware is being considered. The synthesizer is full of interesting quirks and weirdness that I decided to keep in there as I liked how it made me think a bit differently than comparable tools.
These are probably not the version you want
