For those electronic keyboards with an input jack labeled "SUSTAIN," the FC4 model is used in the same manner the sustain pedal on an acoustic piano is used. After pressing down a key, the note will continue to sound utilizing the technology of the FC5 until the sustain pedal is released. The FC5 can also be utilized as an FS controller in synthesizers, tone modules and drum machines.
