MIDI Operation

MPX 500 MIDI Behavior

The MPX 500 “learns” Program Change and Continuous Controllers in its Learn Mode. All of the
parameters controlled by the front panel Edit knobs, as well as the Bypass and Tap buttons are
supported.

As all MPX 500 messages use a single, selectable MIDI Channel, before using any of the MIDI control
features, you should go to System Mode and select the MIDI Channel you want to use. (See

System

Parameters.)

Any of the 16 parameters controlled
by the Edit knobs can be patched
to Continuous Controllers.

Program Change messages can
also be used to load programs.
