The M-Audio SP-1 is a sustain pedal designed for use with electronic keyboards, MIDI controllers, and digital pianos. It provides a traditional pedal feel and functionality, allowing you to sustain notes and chords just like on an acoustic piano. The SP-1 is a momentary footswitch pedal that emulates the sustain function of a piano. When you press down on the pedal, it engages the sustain effect, holding the notes you play until you release the pedal. The SP-1 is compatible with a wide range of electronic keyboards, MIDI controllers, and digital pianos that support a standard 1/4" sustain pedal input
