The SP-Triple pedal from M-Audio performs all the standard soft, sostenuto, and damping functions that your performance demands. Additionally, they add the versatility of 2 and 3 independent 1/4 inch. output cables. This means you can use the SP-Triple with any keyboard that has sustain and/or foot controller 1/4 inch. input jacks. The pedal is assignable to keyboard functions such as patch advance, sequencer stop/start and modulation effects - exactly as you require from a momentary foot controller.
