[sdiy] MIDI inc/dec program

[Forbes, William ALGLSG-LXES]

Hi

Why not keep track of the program number in the controller and then send
program change each time the program inc/dec is changed.
I guess you'll need some way to set the starting number?

Cheers,
Bill Forbes.

Ideally, "any of 'em" - after all, isn't that the point of MIDI?

Specifically, I'm testing this thing with a Roland SoundCanvas SC-155
desktop module. The MIDI details in the back of the manual suggest that
it can't be done. It will accept Data Inc/Dec after setting a RPN or
NRPN, but unfortunately "Program" isn't one of the parameters on offer -
only filter cutoff, resonance, env settings, etc.

The Sysex implementation is pretty sketchy, and seems to mainly be
geared to storing the settings in sequencer. I can't see anything about
program inc/dec.

Pity, it was a nice idea. What else could I usefully use my footswitches
for? Has anyone got any good ideas?

T.
