SINATRA.STY is indeed an all MIDI style, but BIAB by default will automatically substitute a Realdrum for the MIDI drums when it has a reasonably close match, which with this style it does. That's what's causing the issue Andy is having, as I can replicate it on my end.

Andy - on this particular style, you can right click the drums track and choose Force Drums Track To MIDI Drums, and that should solve the distortion issue for you.
