[sdiy] MIDI inc/dec program

[Seb Francis]

Well, strictly speaking CCs 96 & 97 are Data Increment/Decrement, but it 
might control program selection in some synths?
Normally the parameter affected is first set with a RPN or NRPN mesage 
(see CCs 98-101)

Some further reading:

And of course read the MIDI spec of the device you are wanting to control.
