Program Change Formats; Extended Program Changes - Kurzweil PC3K Series Musician's Manual

Program Change Formats

The PC3K can store more programs than the MIDI program change specification can handle
(MIDI lets you send program change numbers from 0 to 127 or 1 to 128 only). So we've designed
a system that makes program selection more flexible. This is true whether you're selecting
programs from the PC3K's front panel, or via MIDI.

The PC3K gives you thousands of program change numbers to work with. These are organized
into 16 banks of 128 each (the memory banks). A program's object ID is its program change
number, as discussed in Chapter 5. This makes it easy to keep track of your programs. The PC3K
can use several different formats for interpreting program change commands. The value for the
ProgChgMode parameter on the RECEIVE page determines which format is used, and the one
you should select depends on your MIDI system.
If you expect you'll always change programs from your PC3K's front panel, selecting programs
is as simple as entering the program change number (the program's object ID) on the
alphanumeric pad, and pressing Enter. Even program numbers above the usual MIDI limit of
127 can be selected this way.

Extended Program Changes

If you're controlling your PC3K from a MIDI device that can handle the MIDI Controller 0 or 32
program‐change format, you'll have the greatest flexibility 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 PC3K 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. Different values have different
results, as shown in the following table:
Program Change Command
Type
MIDI controller 0 or 32
(MC 0 or MC 32)
Standard (PCH)
Bank changes and Program changes. A bank has 128 ids. Note
that our system will recognize 16 banks, from 0 to 15. (2048 ids).
This is for connecting a PC2 or a generic MIDI device as a controller
device.
Bank changes and Program changes. A bank has 100 ids. Our
system will recognize in this case 21 banks, from 0 to 20. For
example, with MIDI out from a K2600 into the MIDI in of a PC3K, if
you scroll or enter a number in the K2600 you will see the same
numbers in the K2600 and in the PC3K if the programs exist.
