I put a little program changer thingie together in PD, cost me 10 minutes.
Pictures would be possible, too, but they would take much longer, require
some 'externals' and I never did use the graphical side of PD. Anyways, to
use this, you'd have to install PD in a recent version, 0.35-test11+ or
0.34 should work, because it uses the rather new GUI objects. Look at
www.pure-data.org for the FAQ, Miller Puckette, the PD author, has
rpm-packages on his website, AFAIR.

To use the pgmchanger.pd, you would start PD like:

$ pd [ -nosound ] -midioutdev 2 pgmchanger.pd

-nosound, because you don't need that, and the midioutdev options points to
you timidity OSS-compatible device + 1 = /dev/midi1 in the example. More
details are in my aconnect-Quicktoot, if you know this.

I implemented only 32 programs, and most without names, but it's easy to
extend the attached patch.

Ciao,
