Out of curiosity, why is this on both u-p.g and c.o.os9?

MIDI is a serial protocol.  Only two of the wires are actually used.
(Ever build a unix-to-unix serial line with just two wires?  That's
they way MIDI works.)

A recent issue of Amiga Transactor had a do-it-yourself RS232 <-> MIDI
project that consisted of one correctly placed resistor.  Now you
just have to deal with the UNIX lack-of-precise-timing problems that 
are involved.  "Dr. Dobbs" has a book called (I think) _C Programming
for MIDI_.  It's wrapped around the PC, of course, but I think you
could easily munge many of the functions to unix.

Also, there is a package "glib" (pronounced as one syllable: "guhlib"),
that is a patch librarian/editor.  It runs on a variety of platforms,
and has code for several major synths (and instructions on how to write
it for your own system).
