I find that Logic drummer is an excellent tool (if, as Floyd says, you are using Logic). I am also assuming you have EZdrummer as you say you have used it.

I was intrigued by this question and tried out an idea. Here's my suggestion...

1. Load the BIAB drum track into Logic.
2. Open a Drummer track, line the start up with the BB drums, fill to the length of the song, and find a similar style from the drummer menu library.
3. In the Drummer Editor click 'Follow' then there is a drop down menu. Choose drums.
Logic drummer will now do a darn good job of following the BB drums. Surprisingly good!
4. In the track strip change the instrument to EZdrummer.
5. In EZdrummer open the mixer window and fade out all the drums you don't want. Let's say you just want the kick and snare - fade the kick and snare in to get the level you want.

Of course you can select whatever kit sounds best for the job.

(If you don't have EZdrummer, use one of the production kits in Logic which allow you to mix each drum on a separate track.)

Another thing to bear in mind is that Drummer always adds 8 bar sections so if you want 12 bar measures you need to cut one, join the 8 and 4 bars together and then copy and paste to the song length. Sometimes endings need some fiddly cutting and adjusting to get them right.

I'm glad you asked this question Roger. By looking into it I now have a really good hack that I will definitely be using in future.

I am a huge fan of Logic Drummer. It is so much quicker than pasting loops bar by bar and the variations available with the editor window makes it possible to vary so many parameters throughout the song. It is far easier than EZdrummer although I do use that for the quality of the instrument sounds. I usually build the drum track using Drummer and then (as I described above) change the instrument to an EZdrummer kit.
