Here's what the problem was: My melody track is using the Plogue Sforzando plugin, which does not support program change messages sent from BIAB.

I'm kind of annoyed, as I liked the sax sound from the HiQ MIDI sound that I used, but I suppose I should be more annoyed with Plogue Sforzando than with BIAB.
