Hoping someone can help me. I just brought a DX7 (Mark1) and had it serviced/Battery changed etc.
I've tried two sustain pedals one piano style (with polarity switch) and the other the footswitch style (fixed polarity)
when I plug the piano one it's sustaining until I press the pedal and when I flick the polarity switch everything wildly sustains with no control at all.
When I plug the fixed velocity pedal in its only reverse polarity.
is there something I'm doing wrong?!
literally at a loss.
