Hi Josie,
When I put my drum tracks together, I have a couple of procedures I adopt.
Firstly, I listen to the BIAB-generated drum track and make a note of any riffs or breaks that I particularly like. If these do not occur in appropriate places in the music, I copy and paste them to the locations that I want them at. Drums are really easy to work with when it comes to joining audio segments.
Secondly, I volume shape the track to highlight the bits I want at different points in the music. The image below shows what one of my typical volume envelopes (in green) looks like after I've used a volume increase to highlight riffs/breaks.
Hope this offers some food for thought
Noel
