I love Zynthian since a long time, and recently I built and sold a midi modular controller.
I made a 4 knobs controller that would fit perfectly with the Zynthian UI, but unfortunately it seems that the UI knobs can be controlled only through GPIO.
I can send any MIDI signal, like relative ones (the same than turntable controllers), or just 2 notes for left/right, or anything in MIDI, even sysex.
I thought about adding a hack to transform MIDI signal to GPIO INPUT signal, but it seems a little bit complicated. Is there an other way to do that ?
Or is it planned to add MIDI control for UI knobs ?
