	Hi,
	I'm don't quite following what your problem is, but to double
check, I d/l'ed 
	http://www.cnd.mcgill.ca/~mat/midi2-jun1303.tgz

	untar'ed it, cd into midi2/mod
	make && make install
	cd ../cmi
	cp /usr/src/sys/dev/sound/pci/cmi.c .
	patch < cmi.c.patch (On mine, one chunk failed because I have
				patched to fix a LOR)
	make && make install
	kldunload snd_cmi
	kldload midi
	kldload snd_cmi

	I'm using:

tube# uname -a
FreeBSD tube.mine.nu 5.1-CURRENT-20031021-JPSNAP FreeBSD 5.1-CURRENT-20031021-JPSNAP #0: Tue Oct 21 01:07:08 GMT 2003 root at ushi.jp.freebsd.org:/usr/obj/usr/src/sys/GENERIC  i386


	I then used midiplay in midi2/midiplay (stolen from netbsd!).
Works fine.  It's a little chunky because the HZ=100, it should really
be HZ=1000, and invariants I think contributes to the sluggishness.
