simultaneously, enabling polyphonic pitch bend and the other expressive
modulations available via 5D Touch.
The receiving instruments that you use must be
multi-timbral
for you to
experience the full expressive capabilities of the RISE. They should have a
pitch-bend range of at least +/- one octave and be able to respond to
aftertouch.
Note
: A
multi-timbral
software or hardware instrument is one that can play
multiple sounds at the same time by using multiple MIDI channels. Here, we’re
using those extra channels for note-by-note expression as opposed to different
sounds.
5.1 Multi-dimensional Polyphonic Expression
(MPE)
The Seaboard RISE supports MPE, which is a protocol for using standard MIDI
messages to communicate with and enable the operation of multi-dimensional
instruments such as the Seaboard RISE. MPE-capable devices can control
multiple parameters of each note independently such as pitch, timbre, and
other nuances when used within MPE-compatible software like Equator. MPE
accomplishes this by spreading MIDI data that pertain to each note across a
range of MIDI channels and reserving one channel (usually the lowest) for
global MIDI messages such as program change, pedal state, and fader
positions. These global messages affect all notes equally. Since each note gets
its own channel, it’s effectively its own sound “program” — even though you
still see a single preset onscreen — and thus can be pitch-bent, filtered, and
otherwise modulated independently of other notes.
