Thank you for your interest! 
I started it to learn Daisy, then it evolved. It is losely based on my Arduino Mozzi machines OscPocketO, Drums and Synth (https://youtu.be/xTlGxCow4GA).
I have recently added a Reverb with reverb send on all tracks, as well as a separate Delay for all tracks. I also added a simple LFO on all tracks that can affect the filter cutoff frequency. This makes it sound more interesting. Then I seemed to have maxed out the MCU, so I had to do some cleaning up.
Only two things missing now:
- SYNC IN/OUT.
- MIDI export.
I hope to finish those things in the week to come.
