Program Change Messages

Reception of MIDI Program Change and Bank Select messages can be selectively enabled/disabled from
Control Mode parameter 3.0 MIDI Pgm Change, or via System Exclusive (sytem parameter 20). The
manner in which the PCM 80 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 Change: On Program Change messages 0—49 correspond to PCM 80 Effects 0.0 —4.9 in the
The current bank can be changed with MIDI Bank Select Messages as follows:

SysEx Automation

The PCM 80 will transmit SysEx automation messages when Control Mode parameter 3.4 MIDI
Automation is set to On. All changes made by front panel operations are transmitted as PCM 80 SysEx
messages. This is intended primarily for use by editor programs and in configurations where it is desirable
for one or more PCM 80s to be slaved to a single PCM 80 acting as a master. In this case, Program
Changes are sent directly via SysEx and are not dependent on Program Change mode.

panel or via SysEx (system parameter 21).
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). The chain can be selected by Program Change (system parameter
22=0) or via SysEx (any other value for system parameter 22).
