Srijan:
I do layered voices using Qsynth, which has two FluidSynth 'engines'
configured. One uses one soundfont, and the other engine a different
soundfont.
I send the same MIDI messages simultaneously to both Qsynth engines.
In more elaborate configurations, I use QMidiRoute to modify the source
MIDI to specify the program-change of the 'background' Qsynth engine,
and use the MIDI 'balance' control to adjust the relative volume of the
'foreground' and 'background' Qsynth engine voices.

Thanks, but shouldn't this be possible using fluidsynth's router?
The fluidsynth API page says you can use the router to "Layer sounds
(Example: for each noteon received on ch 1, create a noteon on ch1,
ch2, ch3,...)". This is exactly what I want to do. For each noteon
received on ch0, I want to create a noteon on ch0 and ch1.
I tried this:
router_clear
router_begin note
router_chan 0 15 0 0
router_chan 0 15 0 1
router_end
But it doesn't work because the second router_chan rule overrides the
first one, so I end up with only one channel playing. I can't get
channels 0 and 1 to play simultaneously.
Any ideas?

On alsa, I would do this with midiecho
http://www.pjb.com.au/midi/index.html
http://www.pjb.com.au/midi/midiecho.html
eg:
midiecho -c 3 -e 3,4 -d 1 -i ProKeys -o FLUID
and then set your ProKeys to play on channel 3.
This doesn't do the "regardless of what channel my controller
keyboard is on" bit. If you just mean for channels 3 or 4,
then I'd start up a second midiecho client using -N
midiecho -N Echo4 -c 4 -e 3,4 -d 1 -i ProKeys,Keysta -o FLUID
but if you mean for any channel 0..15 then I'd probably write
a custom midi-alsa client using either
http://www.pjb.com.au/comp/lua/midialsa.html
or
http://search.cpan.org/~pjb/MIDI-ALSA-1.20/ALSA.pm
<http://search.cpan.org/%7Epjb/MIDI-ALSA-1.20/ALSA.pm>
to do whatever needs to be done.
If you look how important doubling is in orchestral music
it's amazing it's not more discussed in a midi context...
