I worked with a BIAB realTracks song in Logic Yesterday.
I created a new drummer track & selected a drummer I liked.
Hit the Follow click box and had it follow BIAB real track.
Voila, I had a new track that was pretty good

You can easily convert a section of the Logic drummer track to midi within the drummer track.

You can also copy/convert the whole drummer track to midi:
1. Create a new software instrument track (SIT).
2. Copy Channel Strip settings from Logic Drummer track to new SIT.
3 Copy the actual drum part(s) from Logic Drummer track to SIT.
4. The new track will show up as midi. Tweak till your hearts content on the piano roll editor.

This second approach works great for a guy like me who is new to all this. Preserves the original track and I can copy over sections if I really muck one up.

For me it provides a significant enhancement to the BIAB drummer in Logic.
