Program Change Formats
GM programs. When you load the Þles (actually one Þle split over two ßoppies), the K2600
loads the programs into the memory bank you select, and also loads them into Quick-Access
banks, with the programs ordered so that they respond correctly to Program Change
commands. Loading the Þle also changes the value of the ProgChgType parameter from its
default of Extended to QA 0Ð127, so that Program Change commands select programs in the
QA banks.
This allows you to load the GM programs into an empty bank, so you donÕt have to overwrite
any existing objects that have the same IDs as the objects in the GM Þle. Keep in mind, however,
that after loading the GM Þle, non-GM programs will be available only from the K2600. When
sending program changes from your sequencer, youÕll call up the 128 General MIDI programs,
and nothing else. If you want to have sequencer access to both the GM programs and the non-
GM programs, you can change the ProgChgType parameter (found on the MIDI-mode
RECEIVE page) back to Extended. Once you do this, however, any program changes in your
GM sequences will no longer call up the right GM programs, and you will have to insert new
Program and Bank Change commands into the sequence to call up the appropriate programs.
QA Formats and MIDI Transmission
If youÕre in Quick Access mode and youÕre using one of the QA formats for the program change
type, selecting QA banks or bank entries from the K2600 (with the alphanumeric buttonpad, the
cursor buttons, the Alpha Wheel, the Plus/Minus buttons, or the Chan/Bank buttons) also sends
corresponding program change commands to the K2600Õs MIDI Out port.
The nature of these commands depends on the value of the ProgChgType parameter. The K2600
sends either an MC 0 or 32 message followed by a PCH (when ProgChgType is QA Ext), or a
pair of PCHs (when ProgChgType is QA Kurz) or a single Program Change command (when
ProgChgType is QA 0Ð127). The following tables give speciÞc examples.
