Made some more progress on this today. Tested and confirmed being able to power it board off the modular power bus and that hacking on 3.5mm trs jacks works for midi I/O. I can use the encoder switching/control subpatch I’ve already made for my other Axo, so just need to work out a 3 or 4 midi LFO scheme. Hardware seems like it won’t be too bad, but I always seem to end up in trouble on something. haha
