When I load in my GM compatibiity discs my Kurzweil doesn’t receive program changes?

When you load the files (actually one file split over two floppies), 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 file also changes the value of the ProgChgType parameter from its default of Extended to QA 0-127, 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 don’t have to overwrite any existing objects that have the same IDs as the objects in the GM file. Keep in mind, however, that after loading the GM file, non-GM programs will be available only from the K2600.
When sending program changes from your sequencer, you’ll 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.
