The SP-Dual pedal from M-Audio performs all the standard soft and damping functions that your performance demands. Additionally, they add the versatility of 2 and 3 independent ¼” output cables. This means you can use the SP-Dual with any keyboard that has sustain and/or foot controller ¼” 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.
