Pro Audio Support

Q:
My sustain pedal isn't working on my Casio keyboard, when I DON'T press it, it sustains the note, it's working backwards. What can I do?
 
A:
You are using a pedal that is the incorrect polarity for the Casio keyboards. You will need to obtain a sustain pedal which is the opposite polarity (when the pedal is down the switch is on or off). There is no way to change this setting in Casio keyboards.
