--- Comment #3 from Dan Kegel dank@kegel.com 2008-11-24 00:20:16 --- c'mon, I gave a nice repro script. This bug is essentially "too hard to use midi with wine", so if you're having trouble with my recipe, you've reproduced the problem :-)
It seems unlikely that our midi has gotten any love, so this bug is probably still open...
