Kurzweil Program Changes
When you use the Kurzweil program change format, the rules are similar to the extended
format, but when two Program change commands are sent, the first is necessarily of the PCH
type. The receiving end works as follows:
1st program change 2nd program change Result:
command received: command received:
PCH: value 39 None 39th program in current bank select-
ed
PCH: value 99 PCH: value 27 27th program in current bank select-
ed (99 is selected, then overridden
by 27)
PCH: value 102 PCH: value 16 Program 216 (200s bank, 16th pro-
gram
PCH: value 105 PCH: value 44 Program 544
PCH: value 109 PCH: value 0 Program 900
PCH: value 127 PCH: value 99 99th program in current bank (1st
PCH is ignored, since it’s above 109)
PCH: value 127 PCH: value 104 No change in current program; 400s
bank is selected pending next PCH
When you send Kurzweil program changes via MIDI, the K2500 always sends two PCHs. A few
examples:
Front panel selection: program change commands sent:
2 7 ENTER PCH: value 100, PCH: value 27
9 9 ENTER PCH: value 100, PCH: value 99
2 1 6 ENTER PCH: value 102, PCH: value 16
9 1 1 ENTER PCH: value 109, PCH: value 11
Quick Access Banks—Extended (QA BANK E)
Using this setting is similar to using the Extended program change format, but it goes one step
further. When receiving, the 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 changes, without having to switch modes. Second, you
can remap incoming program change commands to select programs or setups with different
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 K2500’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 bank. The QA Bank E 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. The programs and setups
aren’t selected by their IDs, as they normally would be. They’re selected in terms of their
location within the Quick Access banks.
