thanks to Pedro Lopez-Cabanillas, we now have initial ALSA sequencer
support in CVS! I made a snapshot to make testing a bit easier, it's at:


And some instructions:

sh> ecasound -i somefile.wav -o alsa -efl:400 -km:1,400,4200,74,1 -Md:rawmidi,/dev/snd/midiC0D0
sh> ecasound -i somefile.wav -o alsa -efl:400 -km:1,400,4200,74,1 -Md:alsaseq,80:1
sh> ecasound -i somefile.wav -o alsa -efl:400 -km:1,400,4200,74,1 -Md:alsaseq,KMidimon

The first one uses the ALSA rawmidi interface and opens an ALSA device
(card 0, device 0) for raw MIDI I/0. The second example uses the ALSA
sequencer API, which is more powerful as you can route MIDI packets from
and to other applications supporting the sequencer API. "80,1" is an
sequencr port to which ecasound should connect. You can use the "aconnect"
(part of alsa-utils) tool to list all available sequencer ports.

aseqdump and aconnect are nice tools for testing/debugging the
sequencr stuff.
