MPE is the bridge between MIDI 1.0 and MIDI 2.0. The new MIDI 2.0 Profile uses bi-directional communication to define exactly what MPE features are supported for an enhanced user experience.
The MIDI-CI Profile for MIDI Polyphonic Expression (MPE) specification makes it possible for artists to perform independent gestures for each musical note, with up to three dimensions of expression. With MPE, every note a musician plays can be articulated individually for much greater expressiveness.
MPE has broad support from many DAWs, Synthesizers and Controllers.
The MIDI-CI Profile for MIDI Polyphonic Expression (MPE) specification defines an MMA/AMEI Recommended Practice for hardware and software manufacturers to communicate multidimensional control data between MIDI controller instruments, synthesizers, digital audio workstations, and other products, using MIDI messages.
The specification describes a recommended way of using individual MIDI Channels to achieve per-note control, enabling richer communication between increasingly expressive MIDI hardware and software.
