i need to do something relatively simple, but i cant figure out how to do
it, or what software i need...
basically i have to play a certain song where i need to switch between
different sounds (say, a piano at the beginning using qsyinth and then a
synth created with zynaddsubfx). I want to be able to switch between one
setup to the other quickly, possibly using the program change from my
keyboard. How do i do that???
On my keyboard i can create different programs, each using different sounds
(patches) and switch between them with the click of a button. I want to use
that, but I want to generate the sounds with my computer.
I think I need a way to 'map' midi channels to different programs or midi
patches to specific programs (like, when i select piano on the keyboard
(patch0, bank0) it uses qsynth, and when i select a synth it uses
zynaddusbfx).
Any ideas?
Thank you very much,

I had to set up my system to do exactly this thing, and did so almost 4 years ago, and
have been using it ever since for many dozens of gigs and sessions.
I had to write a custom C daemon and some scripts to do it. It's not terribly
well-documented, but it is here:
http://www.restivo.org/blog/archives/midi-splitter
There are some other, more user-friendly tools available to do this though.
I used a CC not program change, but I guess I could just as easly have done it with
program changes, yes.

I do this with channels. I run a B3 on Bristol on channels 1-2, then use
fluidsynth on channels 3-9 for various soundfonts (set the regular piano to
channel 3, the D6 to channel 4, the Rhodes to channel 5, the distorted D6 to
channel 6, etc.)
This has worked fine with only a few small annoyances (e.g. changing the
channel with a note depressed doesn't release the key and if I do this on
the organ I have to change the channel back down to kill outstanding
signals; gain issues between patches, etc).
At my last show I decided to experiment a bit and use a Rock Band 3 keytar
via a MidAir wireless midi adapter. The RB3 controller is midi-compliant but
completely undocumented, and while I have figured out how to do most useful
things on it such as octaves, pitch bend, and modulation, I cannot figure
out how to use any channel except channel 1 (and splitting to channel 10 on
the lower half of the keyboard by pressing one of the buttons -- I forget
which). So I ended up playing the B3 with my keytar, but had to sit back
down at my controller to play anything else, which is a bummer.
I otherwise would've had to shut down Bristol and manually assign a new
patch to Channel 1 in fluidsynth.
The RB3 keytar DOES allow for program changes. So I'm looking for a few
hours to figure out how to change from channel control to program change
control. The problem with that is program change has a specific meaning in
Bristol, so I may have to switch over to Beatrix for my organ if I can't
figure out how to de-assign program change from changing programs in
Bristol. OR I may simply choose a more keytar-y synth to put on Channel 1
and just shift everything else up to 2-10. Somehow the idea of jumping
around on stage with a DX-7 voice is not as much fun as (but maybe more
appropriate than) delivering the enormous B3 sound through a tiny keytar and
a netbook plugged in via DI while making drawbar adjustments with my
controller.
Arg.
It sounds like Ken's solution may be right on the money. Will have to try it
out this weekend.

It sounds like you've figured out most of it anyway, but CDM did a
write-up on the RB3 keytar that covers its MIDI functionality:
http://createdigitalmusic.com/2010/10/hands-on-rock-band-3s-keytar-a-surpri…
Unfortunately it looks like it's stuck on channel 1 with the exception
of that drum split mode you mentioned.
How has the keytar been for you otherwise? I have one myself, but I
haven't done anything serious with it yet.
Thanks

It probably is an overkill for your problem, but I did this small
supercollider program; basically it makes an Alsa midi client to which you
send program changes and it changes through jack connections created by
jack_snapshot. So to use it you would create a jack_snapshot for each
synth/set of connections, save them and put the in "files" variable
Hope it works since I haven't time to test it now and it's been a while
since I've used it... also I remember for some strange reason if I gave it
many program changes rapidly one after the other it would clog the cpu
ah yes, once you have supercollider installed you could simply run it from
command line with "sclang jack-switcher.sc"
HTH,
renato
jack-switcher.sc:
(
//var midichan, files = "jsfiles".getenv.split($ );
var midichan, files;
files = ["/home/renato/Audio/1.snp","/home/renato/Audio/2.snp"];
//these
have to be files obtained through "jack_snapshot save 1.snp"
//Starts MIDI client
MIDIClient.init;
MIDIIn.program = {arg src, chan, prog;
[src,chan,prog].postln;
("jack_snapshot restore
"++files[prog.min(files.size)]).unixCmd;
};
)
