Extended Program Changes
If you’re controlling your PC3A from a MIDI device that can handle the MIDI Controller 0 or 32
program-change format, you’ll have the greatest exibility if you set the ProgChgType parameter
to a value of Extended.
When you’re using the extended program change format, then depending on the value of the
BankSelect parameter on the RECEIVE page in MIDI mode, the PC3A will respond to either
MIDI Controller 0 or 32 program change commands for bank selection, and standard program
change commands for program changes within the current bank. Dierent values have dierent
results, as shown in the following table:
Program Change Command
Type
Value of
Message
Result
MIDI controller 0 or 32
(MC 0 or MC 32)
0 to 16 Selects memory bank zeros–900s
Standard (PCH)
0 to 127 Selects correspondingly numbered program in current
memory bank
If your PC3A is already in the memory bank you want to use, you can send it single PCHs from 0
to 127, to select programs within that memory bank. The PC3A’s response depends on the setting
for the Bank/Select parameter on the MIDI Mode RECV page. If you want to change the memory
bank, the PC3A must receive either an MC 0 or 32 message with value 0–127. The next PCH in the
range 0–127 will select the correspondingly numbered program in the newly selected bank. The
following table of examples should help make it clear.

Result
MC 0 or 32: value 0 PCH: value 99
Program 99 (Base1 bank, 99th program)
MC 0 or 32: value 1 PCH: value 41
Program 169 (Base2 bank, 41st program)
MC 0 or 32: value 1 PCH: value 129
Program 258 (Classic Keys bank, 2nd program)
MC 0 or 32: value 7 None

selection is pending for next PCH)
QAccess
Using this setting is similar to using the Extended program change format, but it goes one step
further. Incoming program change commands are interpreted just as they are in the normal
Extended format. But the resulting program change number, instead of selecting a program,
selects a Quick Access bank entry (you must be in Quick Access mode for this to work). There are
two advantages to using this format. First, it allows you to select both programs and setups using
program change commands, without having to switch between Program and Setup modes.
Second, you can remap incoming program change commands to select programs or setups with
dierent IDs. This is handy if the sending unit can’t send program change commands higher
than 127.
First, a brief review of Quick Access bank structure. Each Quick Access bank can store ten entries,
each of which can be a program or a setup. Each of the PC3A’s 10 memory banks can store 20
Quick Access banks (except the Zeros bank, which can store 75). Therefore when you’re in Quick
Access mode, you have access to 200 (or 750 in the Zeros bank) programs or setups without
leaving the currently selected memory bank. The QA Ext program change format lets you select
any one of those programs or setups via MIDI. If you select another memory bank, you have a
