With the help of Takashi Iwai, I've written the MIDI routing application
(92 lines) you have been asking for. It creates one writeable ALSA (0.9)
sequencer port and two readable ports. The program takes the parameter
"pick_channel". MIDI events with channel equal to "pick_channel" are
routed to the first readable port. All other events are directed to the
second one. ALSA has a built-in virtual rawmidi-device which you can use
as destination after you have configured the soundcard snd-virmidi.

Have fun !
