I found myself harkening back to a time when editing midi files with sequencer software, note for note, with multiple tracks, was a basic modus operandi for building song files, or backing tracks. God forbid that anyone would have to resort to copy editing note for note, by hand, accomplishing the same notation for readers. I digress on the distracting topic of what seems too much detail to have to manage... For the original poster - find a BIAB midi style that's close to the end style you need, with particular attention to a few critical key instrumental tracks, that sound great as is; assemble your preferred ensemble of instruments; input chords; generate a midi song file; save it; open it up in Real band or BIAB, or your preferred sequencer software product, and edit the tracks that need attention, and viola! Midi song file, or backing tracks. Isn't this how many of you used to customize song files for use? Now with Real Tracks and other audio editing software that enable editing of both wave based tracks, as well as midi tracks, all can be combined, though you need to know your way around audio file editing or loop editing software products, that have the editing features for midi tracks you want to combine... And, dare I suggest, I think you can do it all in BIAB... Amazing product...!
