MPX 1 User Guide

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 1 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 correspond to MPX1 programs 1-100. Pro-
gram 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 1 program. When first shipped, the MPX 1 has each map
loade with the following defaults:

Map 1, 2 or 3

MIDI 1 = Program 1

MIDI 128 = Program 128

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).
