MIDI Polyphonic Expression

MIDI Polyphonic Expression (MPE) is the biggest change in electronic sound since the invention of the synthesizer. Dozens of hardware and software companies have now joined this movement to make music creation tools more expressive.

A NEW WAY TO CREATE

What is MPE?

MPE is a new specification based on MIDI, the universal protocol for electronic music. MPE allows digital instruments to behave more like acoustic instruments in terms of spontaneous, polyphonic sound control. So players modulate parameters like timbre, pitch, and amplitude — all at the same time.

MORE EXPRESSION

Imagine what you can do with MPE:

  • Icon bullet point
    BEND PITCH, modify volume, and play with resonance at the same time — like on a string instrument
  • Icon bullet point
    SLIDE BETWEEN SOUNDS, or brighter and darker versions of a sound, like sliding between notes on a piano
  • Icon bullet point
    SAVE TIME by achieving sonic effects through intuitive gestures, rather than laborious programming
  • Icon bullet point
    ADD SPONTANEITY to your music, because more parameters of sound are available to play with

MPE is breaking through

Explore a brief history of MIDI Polyphonic Expression

Makers of new ‘multidimensional’ controllers — including Roland Lamb, Roger Linn and Keith McMillen — meet at the NAMM show in California with software developers to discuss how to make MPE a reality.

Hardware and software creators begin to develop the blueprint for an official MPE specification, building on the universal protocol of electronic music — MIDI. Meanwhile, more musicians and producers discover the new, expressive language of MPE.

In a historic moment for electronic music, the MPE Specification is officially adopted by the MIDI Manufacturers Association. This blueprint makes it easier than ever for companies to design new MPE-compatible instruments.

More on MIDI

MPE is built on MIDI, the universal protocol governing electronic music. MIDI was established in 1983 and now used on billions of devices and software programs every day.
