MIDI Operation
Most MPX G2 parameters and all programs can be accessed by MIDI. All MIDI
applications require the MPX G2 to be connected with one or more MIDI devices
with standard MIDI cables via the rear panel MIDI jacks.
MIDI controls, such as Transmit and Receive Channel selection are available in
the System mode MIDI menu. All of these controls are described in Chapter 5:
System Controls. Several are repeated here for your convenience.
Before using the MPX G2 with other MIDI devices, all devices must be set to the
same MIDI channel. To set the MPX G2 to receive MIDI:
1. Set the controller you will be using (keyboard, sequencer, other MPX G2,
etc.) to transmit on any MIDI channel (1-16).
2. On the MPX G2, press System. Use the knob to scroll to the MIDI menu.
Use the < and > buttons to select MIDI Receive.
3. Use the knob to select OFF, 1-16, or OMNI for receipt of MIDI messages.

Some extremely useful effects can be created by controlling MPX G2 param-
eters remotely in real time. Almost all of the controllers found on a MIDI keyboard
or MIDI foot controller (pitch benders, mod wheels, sliders, switches, breath
controllers, foot pedals and footswitches) can be used to adjust MPX G2
parameters. We refer to this real time remote control capability as Dynamic
MIDI.
®
Sending a MIDI Program Change message from the controller will load an MPX
G2 register. If any MIDI sources are active as global or general purpose patches,
moving the appropriate control on the controller will cause the patched destina-
tion parameter to change. (See Chapter 4: Patching.) If you want to use Dynamic
MIDI, but don’t want the MPX G2 to load new registers when you change
programs on your controller, set your controller so that it doesn't transmit
Program Change messages, or set MPX G2 Pgm Change to Off in the System
mode MIDI menu.

JamMan NOTE
When the JamMan effect is loaded
(Delay block) and the MIDI Clock
Output parameter (in the System:
MIDI menu) is enabled, a MIDI
Start message is sent at the end of
the loop definition. A MIDI Stop
message is sent when the loop is
reset or the MuteS (Start/Stop) pa-
rameter is used. (MIDI Stop on
mute and MIDI Start on de-mute.)
