A possibly-related data point: having recently updated my kernel to one
that includes the in-kernel mixing, MIDI files played by timidity now
sound awful.  As far as I can tell, every note gets cut off as soon as
another note is played.  You can imagine what a mess that makes of
chords.  Before the kernel upgrade multi-part MIDI files played
normally.  This comparison is old-OSS vs new-OSS, not OSS vs pulseaudio.
That suggests to me that something has changed in the way the new OSS
code handles a series of sound samples sent to the same logical output.

That could be a completely unrelated problem of course, but it might
be a clue.
