Ideas:

1. Did this song begin by importing a MIDI file? Perhaps there are control codes that are affecting this song.

2. Try the remedy that used to work when we encountered this problem: save the file while the song is playing. I haven't had to do that in a long time, but you did not mention what version of BIAB you have.

3. Opt, Return to Factory Settings. Yes, I know it's only one song, but just in case...

4. Are the Real Tracks frozen?
