Behringer US600 Ultra Shifter/Harmonist stompbox has an ability to shift sound pitch, also controlled by expression pedal. In this test movie, Arduino is controling the degree of the synthesizer sound pitch.
This is really interesting. How exactly does Arduino control the pitch? I understand you're hooking it up as an expression pedal, but how does it work? Is Arduino sending voltage to the pedal?
Arduino is working without expression pedal. It's outputting LFO voltage via analog port.
