Reception of MIDI Program Change and Bank Select messages can be
selectively enabled/disabled from Control Mode parameter 3.3, MIDI Pgm
Change. The manner in which the PCM 90 interprets these messages is
determined by the value of this parameter as follows:
Pgm Change: Off
All Program Change and Bank select messages are treated as "unavailable".
Pgm+ and Pgm– will load the next higher or lower program in the current bank,
then wrap to the adjacent bank.
Pgm Change : On
Program Change messages 0-49 correspond to PCM 90 Effects 0.0 -4.9 in the
current bank. Program Change messages 50—127 are ignored. Pgm+ and
Pgm– will load the next higher or lower program in the current bank, then wrap
to the adjacent bank.
The current bank can be changed with MIDI Continuous Controller 32 and Bank
Select Messages as follows:
0-4: Program Banks 0-4
5-6: Internal Register Banks R0 and R1
7-11: reserved for ROM Card Banks
12-...: Memory Card Banks
The number of banks available on a given card will vary with card
size as follows:
Card Size # Banks
64k 1
256k 5
512k 10
1 Meg 20
Pgm Change: Map
Program Change 0-127 can be mapped to any PCM 90 Effect in any internal or
card bank. Two 128 element maps are stored internally, additional maps may be
stored on RAM cards.
Map 0 Map 1
MIDI 0 = P0 0.0 MIDI 0 = P2 2.8
MIDI 127 = P2 2.7 MIDI 127 = R 4.9
Pgm+ and Pgm– will load the next higher or lower program in the map.
Pgm Change: Chain
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).
Note: The PCM 90 requires a brief amount of time to change programs.
Additional Program Change messages received during this time out may be lost.
