If your sustain pedal plugged into a Yamaha keyboard is producing the opposite effect - sustaining when the pedal is not depressed, and not sustaining when it is depressed - it's usually because the pedal was plugged in while the keyboard was turned on, or the pedal was depressed while the unit was powering on. This tricks the keyboard into thinking the default state of the pedal is depressed, resulting in a reverse polarity or reverse function.
To fix this issue, follow these steps:
1. With the unit turned on and the sustain pedal plugged in, depress and hold the sustain pedal while you power the unit off.
2. Release the sustain pedal once the unit has been turned off.
3. Turn the unit back on.
That usually fixes the reversal of polarity. If you're using a non-Yamaha sustain pedal, those sometimes have polarity switches that may solve the problem without the need for the steps above. If the issue persists, please contact Yamaha Support staff for further troubleshooting.
