Sorry to see so little feedback to this thread. Not a surprise since there is only a few who continue to support this program. But where are they?

I tried to confirm using the BIAB Standalone VST - I got no sound at all. Then I opened Reaper and the BIAB-VST. Loaded the demo from the style you indicated and transfered all rendered tracks to the DAW. The single drum track played thru the entire song so I could not confirm your reported issue. However, there was something wrong with the drum sounds. I muted ALL tracks and instead of silence, drums continued to play from the VST. But these were not similar to the style. I was unable to identify where the drums were coming from since all tracks in the VST were muted along with all audio tracks in the DAW. By the way, to the best of my recollection, what you are reporting has been seen frequently in the past in the developer forums.

Good Luck.
