== 2007-08-28 (Tuesday) - Reverse engineering the program change to instrument mapping == | |||
Been trying to reverse engineer the Apple IIGS AGI MIDI files' program change command's | |||
parameter value to instrument number mapping recently. Tried a few approached that didn't work | |||
but came up with a way that works quite well. Here's the preliminary mapping from | |||
program numbers to instrument numbers (Instrument number 6 seems to be mostly used to | |||
mean an "undefined instrument" or a "not used instrument"): | |||
Programs 0-9: | |||
* Instruments: 21, 22, 24, 25, 23, 26, 6, 6, 6, 6 | |||
Programs 10-19: | |||
* Instruments: 7, 9, 12, 8, 13, 11, 17, 10, 6, 6 | |||
Programs 20-29: | |||
* Instruments: 19, 18, 20, 14, 16, 6, 6, 6, 6, 6 | |||
Programs 30-39: | |||
* Instruments: 0, 1, 2, 4, 3, 5, 17, 2, 2, 2 | |||
** The trailing 2's are probably somehow modified so they don't sound identical | |||
Programs 40-49: | |||
* Instruments: 27, 15, 15, 27, 6, 6, 6, 6, 6, 6 | |||
