If you just typed Cb9, it would think it's a variation of a C-flat chord. And unfortunately, BIAB doesn't support typing C9b, such as it does for C5b (to avoid confusion with a C-flat 5). I think the closest you'll get is a C7b9 (which you already discovered). Maybe that should be a wishlist item, although at this point, I doubt you'll get any RealTracks to play it; it would be MIDI only.
