MIDI Operation
MPX 100 MIDI Behavior
The MPX 100 “learns” MIDI Channel, Pro-
gram Change and Continuous Controllers in
its Learn Mode.
Any of these controls can be patched
to Continuous Controllers.
These buttons can also be
patched to Program Change.
As many as five Learn patches (for the
front panel Mix, Effects Lvl/Bal, Adjust,
Bypass and Tap controls) on as many as
five MIDI Channels are supported.
Program Change messages 0-15 are re-
served for executing program loads on any
learned MIDI Channel — or a separate MIDI
Channel can be selected for program load.
Program Change messages can
also be used to load programs.
