Hi
I've got the same problem with a waltz style I wanted to use.
The tracks in my case were all midi, and the real drum track for the style just didn't suit.
I haven't tried the fixes mentioned above, I'm fairly certain I should just be able to replace the real drum track with a midi drum track from another waltz style if the fixes above don't work.
Been a couple of years since I last used biab, and the style creation functions, back then the style creator allowed you to do all sorts of things.

I haven't gotten round to trying to edit the style as yet.


best wishes
rikki
