Drums and loops have always seemed to work somewhat outside of the normal BIAB and are more restricted than other instruments in my experience. It appears you are having to post-edit (DAW) rather than generate (BIAB). I believe Noel is correct that midi drums and loops in BIAB "try and replicate a live performance where notes vary from performance to performance. It is unlike a loop that involves strict repetition of a musical phrase over and over."

That said, my thought is there may be other alternatives within BIAB that will accomplish the task with a clearer understanding of the steps you are currently taking to get the tracks you want. I'm curious to know more about what you're doing.

Why can BIAB2 search for midi drum styles and BIAB1 can't?
How are you auditioning BIAB drum tracks in your DAW?
What is your processing sequence when you drag it into Ableton?
Do you import your Ableton track back into your BIAB project as midi or audio?
