M-audio Expression Pedal Manual Guide

No. Sustain pedals are on/off (switch type), while expression pedals send continuous values.

Safety Warning: Do not plug a cheap on/off sustain pedal into the expression jack. It will short the circuit and may damage your keyboard. Use only a TRS expression pedal with a potentiometer. m-audio expression pedal manual
