The Seaboard GRAND, RISE, and BLOCKS use MPE to transmit their dimensions of touch as standard MIDI messages on multiple channels to achieve Expressive Polyphony.

  • Each note is sent on an individual channel
  • Messages which would normally influence all notes (like pitch bend or continuous controllers) can be expressed polyphonically.

In MIDI, pitch bend and CCs (Continuous Controllers) are channel-wide messages, meaning that they apply to all notes being performed on that channel. An ordinary MIDI controller sends all notes on the same channel so the pitch bend or CCs are applied to all of those notes equally. For example, if you hold a chord on a normal MIDI keyboard then move the pitch wheel, all the notes will bend together.

By using a separate channel for each note the Seaboard is able to transmit these controllers individually for each note – without influencing the other notes being performed.

This means that when recording the Seaboard’s MIDI data, your DAW must be able to receive and record multiple channels. If the pitch bend or CC data for several notes is summed into one channel, they will clash and the sound will be erratic.
