Program Change Formats
If your K2500 is already in the memory bank you want to use, you can send it single PCHs from
0 to 99, to select programs within that memory bank. If you want to change the memory bank,
the K2500 must receive either an MC 32 message with value 0–9, or a PCH with value 100–109.
This will select the new memory bank, but will not change the current program. The next PCH
in the range 0–99 will select the correspondingly numbered program in the newly selected
bank. The following table of examples should help make it clear.
1st program change
command received:
PCH: value 64
PCH: value 99
PCH: value 102
PCH: value 127
PCH: value 127
MC 32: value 0
MC 32: value 1
MC 32: value 9
MC 32: value 9
MC 32: value 10
That's the receiving end of extended program changes. On the transmitting side, the rules are
similar; if you select a program in the current or another memory bank, two commands are
sent. The first selects the memory bank, and is always an MC 32 type. The second is always a
PCH. Some examples follow. They assume you use the alphanumeric pad, but you could use
the other data entry methods as well.
