PROGRAM CHANGE MESSAGES
LOADING PROGRAMS
Standard MIDI Program Change messages can be used
to load all 255 presets and 64 user programs. The unit
conforms to the use of MIDI Continuous Controller 32 to
execute Bank Select messages. MPX 550 program banks
are ordered numerically from 0 to 27, beginning with
the Plate Bank. (See the table at the right for additional
bank numbers.)
Any program can be loaded by selecting its bank with
Controller 32, then sending the appropriate Program
Change message.
For example, if the Plate Bank is selected:
• Sending Program Change 1 will load the first Plate
program (Small Plate).
• Sending Controller 32 with a value of 27 followed by
Program Change 1 will load the first program in the
User Bank.

• Sending Controller 32 with a value of 1 followed by
Program Change 2 will load the second program
(Slope Down) in the Gate/Inv Bank.
Once a bank is selected, all subsequent Program Change
messages will select programs within that bank until a
new value for Controller 32 is received, or until another
program or bank is selected with the front panel
PROGRAM knob.
MIDI Program Change messages can be disabled in
System Mode with the MIDI Program Change
parameter.
