I mean as of now all I've done are a few experiments with PCM. I made this by rigging up a google colab to turn audio files into P8 strings. Then bikibird came up with Defy, which is a much better solution than my janky uncompressed one. The most recent thing I made is a terrible "game" I made as a joke.
Luchak made a FANTASTIC ReBirth-ish groovebox program though! I'm planning on like...making a whole album using it alone lol
