Yamaha FC5 Sustain Pedal
Yamaha offers many different foot pedal/switch/controllers for a variety of functions. A compact version of the FC4, the FC5 performs similar to an acoustic piano’s sustain pedal providing expression and feeling to any performance. The FC5 can also be used as a hands-free on/off switch for activating effects or even recording. 5′ cable, 1/4″ plug.
If a 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 (a) the pedal was plugged in while the keyboard was turned on, or (b) 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. There’s an easy way to remedy this:
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.
