hi James, I haven't found the problem yet, but I've narrowed down when it came in. As far as I can tell the latest "safe" version where it was ok is 0.045. It's bad in everything beyond that, so I'm in for more long sessions of scouring diffs. Until that comes up with something, if you really need the Space Choirs maybe 0.045 (from last December) could serve your needs better. <http://www.graggrag.com/yoshimi/yoshimi-0.045.tar.bz2> cheers, Cal
