... The only thing is what sort of switching do the buttons require. When I put a continuity tester on my pedals it shows they are completing the circuit when untouched but breaking when pressed is this correct.
Hi shezza,
yes, you are correct: Yamaha foot switches (FC5, FC4A) have "normally closed" electrical contacts. The contact opens when the pedal is pressed.
But, as already mentioned by Colin, you can also use switches with "normally open" contacts. The pedals/switches should be connected before powering on the keyboard. Then normally the "Polarity" of the pedals is recognized automatically. If the pedal still works "reversed", just call up the "Assignable" display (press "Direct Access" button, then press the pedal) and change the Polarity from + to - (or vice versa). Then
close the "Assignable" display to save the changes.
Best regards,
Chris
