“PC”: Program Change
Program change events can be used to switch voices at any point in the track. The program change parameter has three sections: The MSB (most significant byte) of the bank select number, the LSB (least significant byte) of the bank select number, and the program change number itself. The bank select number parameters can be set from “000” through “127”, while the program change number parameter can be set from “001” through “128”. The bank select parameters are only useful if you’re sending program change data to an external device that recognizes bank select numbers. Normally you’ll use only the program change number. Using the program change number (the bank select parameters should be set to “000”) you can select internal voices “001” through “128”. The name of the selected voice will appear to the right of the program change number.
