Pedal Polarity Issues

If your pedal stops sustaining the notes when you press it down, and sustains the notes when you lift it off, then you have a pedal polarity issue. You either have the wrong type of pedal for your keyboard or electric piano, or your pedal is incorrectly configured for your keyboard.

There are two types of midi sustain pedals:-

sustain pedals with polarity as "+" (positive)

sustain pedals with polarity as "-" (negative)

 

Manufacturing defaults with sustain pedals

Yamaha sustain pedals (such as the fc4 and fc5) are "-" (negative) polarity (normally closed position)

Roland sustain pedals are "-" (negative) polarity (normally closed position)

 

Casio sustain pedals are "+" polarity (positive) polarity (normally open position)

Korg sustain pedals are "+" polarity (positive) polarity (normally open position)

 

 

Solutions and answers for the pedal polarity issue:-

If you are not sure which polarity works with your keyboard, buy a dual polarity pedal, such as the spectrum dual polarity sustain pedal, with it's in-built switch that can flick the pedal between "+" and "-". The M-Audio sp-2 also has a polarity switch.

Obtain the correct polarity pedal for your keyboard (see guide above)

Some keyboards allow you to change the way that polarity is received in the keyboard, and toggle between "+" and "-". Consult the setting options in your manual to see if this may be possible.
