[ltp] ALSA support for FM sequencer

[Thomas Hood]

FYI, regarding ALSA support for FM sequencer:

I recently asked about this on the alsa-devel mailing list
and I received the following useful reply from Uros Bizjak.
Summary: support should be there by ALSA 1.0, which is 
scheduled to come out in a few months.    // Thomas

Generic OPL3 MIDI is supported in 0.9beta1.

[You need the] snd-synth-opl3.o module.
 
snd-opl3.o is not used for MIDI functionality, only for
direct-FM synth.

playmidi should work out-of-the-box, and to use pmidi, you'll have to
load FM instrument paches first (by using sbiload application). It
worked for me a couple of weeks ago.

Unfortunatelly, there is something broken in sequencer subsystem and
neither playmidi, nor pmidi work with current CVS sources.
