Jup, ChibiOS based firmware, the synth is currently written in Faust, but I’m also looking into making it run (modified) Axoloti patches. And maybe there will be some cross breeding with Daisy too, curious what that will bring. The synth is not yet in the current firmware, but will be open source too. I myself will focus on one good sound, but switching sounds should be not too hard to implement. That might need some community effort
Tuning systems are currently anything in the syntonic tuning continuum, so meantone tunings, 12tet, 31tet, 19tet, 5tet and 7tet. JI tuning systems not yet, I do have some ideas but never worked it out completely.
It don’t plan on including a battery, I want to be a bit careful with taking on too much. And since there’s no speaker you need a wire anyway for the sound.
@thetechnobear, Would be great to see what code you come up with! It’s so great to see you being involved in so many open source projects!
