How do you reverse the polarity on the foot pedal. I need it to work like a piano sustain, not a keyboard sustain.

SOURCE: is a sustain foot pedal similar to a tattoo machine pedal?

The sustain pedals have only two wires. Usually they terminate in a 1/4 inch mono plug.

yamaha USUALLY sustains when switch is closed. Roland usually sustains on a switch between the wires when the switch is open.

NO POWER should be supplied BY the sustain pedal... it is ONLY a switch.

SOURCE: How do you make the sustain pedal work correctly?

If you are not using the original pedal it means that your pedal is wired backwards. You can try disassembling the pedal or the plug on the cord and reversing the wiring of the connections to see if that helps. Example if the shield of the cable is wired to the shaft of the plug, try disconnecting the wiring to the shaft and tip and wire the shield to tip etc.

SOURCE: I've recently purchased a Roland

Sorry, but Roland uses the opposite sense switch. They use normally closed where Casio requires normally open contacts. SOMETIMES one can rewire the pedal internally, but you have to be mechanically and electrically inclined to do that.

Yep... Roland pedals are reversed, that is, normally closed contacts. Unlike some Yamaha keyboards, the Casio doesn't have an inversion function available. You have two choices to solve this: 1. Buy a pedal with the corect sense 2. Open the Roland pedal and MAYBE with a soldering iron you can move a wire to select a contact with the opposite sense.
