Primarily BIAB is a practice aid - meet my "Electronic Ensemble".

Other than that I often export MIDIs from NWC (Noteworthy Composer) and use BIAB to add a drum kit and occasionally a bass line - sometimes some ideas for brass as well, but mainly the drum kit - which I re-imort via MIDI - much easier than typing it in... This is for the home grown stuff some of the more creative muso's at my church write.

You're only paranoid if you're wrong!
