C.1.6 Data Structure Per Program
All programs use the following data structure. Each program parameter has a specified offset
within the Edit Buffer. By reading or writing these parameters, you can query or set particular
program parameters. By dumping the entire range (0-99d), you can look at the status of the
entire edit buffer. By reloading the same range, you can superimpose your own values onto the
same parameters. (You can also modifiy any value individually via MIDI.) You'll need an
external MIDI program editor to perform this task. For clarity, each function is presented in its
own table, however the offsets shown refer to a contiguous block of memory in the unit.
