THat's OK. I'll just solder in a jack in parallel with the momentary button for the rotary. Problem solved. Probably easier than the programming would have been anyway!!
How do I program the sustain pedal (or any other) to control the rotary speed from low to high (on and off)??? I've read and read and read, and can't figure it out... I need both hands free to play!!! Can anyone give me a step by step to accomplish this please??
