That does help and is quite interesting.

Whether it's for practice or for recording, these days I almost always use BiaB simply to make jazz rhythm-section MIDI tracks that I can import into Logic. Having BiaB in a "plugin" relation to Logic -- the great new feature of 2010.5 as far as I can tell -- should save me several steps.

For the tracks' instrument sounds, often I use Logic's samples, driven by the BiaB MIDI track, rather than BiaB's own RealTracks. (Am I really missing something as a result?)

Thank you.
