I just got my JABB yesterday and I've been playing with it a bit. It's a wonderful tool but there's this one thing that annoys me. I don't know if it's a bug or something but when I play the saxophones the AirNS level jumps abruptly to a very noticeable level. After I bring it back to zero and play for a couple of seconds it jumps back up. This happens whenever I touch the Mod wheel and sometimes even if I don't.
Airflow noise responds to CC12. Modwheel is typically assigned to CC1. Is there any CC12 information in your midi track? Breath noises are also located towards the top of the keyboard. Are you hitting these keys in passing?
