MPE

MIDI Polyphonic Expression

Live 11 finally introduced MPE. MIDI Polyphonic Expression (MPE) and Midi are both standard protocols containing note and time information. MIDI associates all parameters of data to a single channel, MPE does this with each note. Every note can have its values changed in realtime.

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. roli.com/mpe
