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 PC3’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 different set of 200 programs and setups at your disposal. When you’re using this
format, the PC3 will respond to MC 0 or 32 messages for selecting QA banks, and to PCHs for
selecting entries within the current bank. PCHs select entries according to their “chronological”
listing within the QA bank (not according to their IDs).
Depending on the QA bank entry you want to select, you’ll send the PC3 either a PCH (value 0
to 99), or a MIDI Controller 0 or 32 message (value 0 to 7) followed by a PCH. Sending a single
command will let you select from a range of 10 QA banks and select an entry within that bank
(see the table below). To select a different range of QA banks, send an MC 0 or 32 message
followed by a PCH.
The MC 0 or 32 messages selects the range of QA banks (0s through 70s), while the PCH selects
the bank within that range, as well as the entry within that bank. Neither the MC 0 or 32 nor the
PCH selects a different memory bank (Zeros through 900s). In fact, you can’t change the memory
bank via MIDI when using this format. All program and setup selections are made within the
currently selected memory bank. You’ll know which memory bank is selected by looking at the
ID of the currently selected Quick Access bank in the top line of the Quick Access mode page.
