Multi Polyphonic Expression – The Future of Keyboard Expression

MIDI technology has remained one of the most influential advancements made to music production ever. MIDI keyboards are a staple in the producer's toolkit, letting us communicate between our machines since the 1980's. The one-man-band was hardly realized before the ability to control multiple devices at one time from one place happened, thanks to MIDI. While it's been nearly 40 years since the invention of the Musical Instrument Digital Interface protocol, and while other facets of music tech have moved forward we have seen few significant improvements made to MIDI in this century... until MPE.

MPE is an abbreviation for Multidimensional Polyphonic Expression, which transforms the way to express your playing on MIDI instruments. Normal MIDI messages are limited in that they are applied on a channel-wide basis, messages apply to every note at the same time; if you throw your pitch bend up on that sweet Diminished chord then each note you are pressing is going to bend. MPE utilizes MIDI in a way that allows control over multiple parameters of every note, on each note individually. New controllers have emerged in conjunction with MPE communication to best utilize the expanded capabilities of the technology, i.e. the ROLI Seaboard:
