Erae 2 is a MIDI Polyphonic Expression Controller (MPE), which is a relatively new standard for expressive electronic music performance. It enhances MIDI by allowing each note played to be controlled independently on its own MIDI channel. This enables expressive features such as pitch bends, vibrato, and dynamics for individual notes in a chord, rather than applying these effects uniformly to all notes.

‍

All pitched elements (such as keygrids, keyboards, and drum pads) can operate in MPE mode by enabling the MPE button either in the Erae Mapping section or the Lab’ Tune section.
