Most MIDI 1.0 controllers are limited to note on/off, velocity, and three global expressions – pitch bend, modulation wheel, and aftertouch. Some advanced controllers have used polyphonic aftertouch to provide one additional dimension of per-note expression.

MIDI Polyphonic Expression (MPE) is a recent update to the MIDI 1.0 protocol that allows per-note control of pitch bend, modulation wheel, and aftertouch.

KMI makes several MPE and Polyphonic Aftertouch capable controllers that utilize some or all of these forms of expression.

KMI MPE and PolyAT Controllers

  • K-Board Pro 4 is a dual zone MPE controller. Every key of the silicone keyboard sends velocity, pitch bend, modulation wheel, aftertouch, and release velocity. For synths that only support Polyphonic Aftertouch, the K-Board Pro 4 can map the key slide/Y axis (cat claws) to PolyAT to create an "MPE like" experience.
