Re: [vox-tech] timidity

Sort of... but not really.

DOSEMU needs /dev/sequencer to play MIDI, but if you don't have
/dev/sequencer you can tie it to Timidity to simulate a MIDI device.  As
you mentioned, Timidity can be used as an Alsa sequencer client, but
DOSEMU gives an extra way to access Timidity if you don't have an Alsa

DOSEMU comes with a program called "midid."  You can launch Timidity as a
MIDI server on a TCP port (via the -ir option), then you can run midid on
that port and a named pipe.  If you send MIDI events to the named pipe, it
gets routed to Timidity's MIDI server by midid, and voila... you got a
MIDI sequencer simulator:

   $ mknod ~/.dosemu/run/dosemu-midi p
   $ timidity -ir 8080 -B 1000 &
   $ midid -p8080 ~/.dosemu/run/dosemu-midi

The only problem is midid is not a complete program.  It only seems to
work nicely with DOSEMU.  If you try to send a MIDI file directly to the
named pipe, it gives a warning about unimplemented reset MIDI message.

Looking at the midid sourcecode, though, it looks like it wouldn't be
terribly difficult to fudge the missing code.  It looks like you just need
to flush the input data so it ignores the unimplemented messages
(currently it seems to not flush the input data and just gets stuck in a
loop.)  MIDI is a pretty simple format; maybe you can take a shot at
fixing up midid.
