MIDI Operation

Reception of MIDI Program Change and Bank Select messages can be selectively enabled/disabled from the System mode MIDI menu. The manner in which the MPX G2 interprets these messages is determined by the value of this parameter as follows:

Pgm Change: Off

All Program Change and Bank select messages are ignored. Pgm+ and Pgm– controllers will load the next higher or lower program in the current bank.

Pgm Change : On

Program Change messages 0-99 are recognized. Program Change messages 100—127 are ignored except when MIDI maps or chains are active.

Pressing Options from the Pgm Change display allows you to select a Pgm# Offset (to allow matching of MPX1 program numbers to another MIDI device) or to map Pgm+ and Pgm– controls to load the next higher or lower program in the current bank.

Controller 32 is used to select Banks.

Program memory is organized into three banks as follows:

Program Bank 1 Preset programs 1-100

Program Bank 2 Preset programs 101-200

Program Bank 3 User programs 201-250

Three 128 element MIDI maps are stored internally. Program Change 0-127 can be mapped to any MPX G2 program. When first shipped, the MPX G2 has each map load with the following defaults:

Map 1, 2 or 3

MIDI 1 = Program 1

MIDI 128 = Program 128

Program Change Messages

Pgm+ and Pgm– will load the next higher or lower program in the map.

Any Program Change number can be selected to load any one of ten customized effect “chains.” Once a chain is loaded, effects in the chain are accessed by the controller patched to Pgm + and Pgm – (program increment and program decrement).
