Thanks. I wish I did too. But as it turns out I didn't. I set up a 32 bar song to play at 160bpm, with style _JBRF_B.STY, whose tempo is also 160. I am not using the woodshed increasing tempo here; the tune just plays at 160. Every instrument except the drums produces artifacts from the first bar forward. The result would not be usable in performance (if I'm ever permitted in public again), which is the goal. As before, a pure MIDI style (ZZJAZZ)plays without incident, but I do not want to be restricted to MIDI. The real tracks are a major reason I use BIAB, and without them the product loses much of its value for me.
