Not sure if this fits here; but, the Yamaha arranger keyboards have a feature (can't think of the name) where sample styles and registrations are preset ready to call-up based on tunes that most players know. They use cryptic names, such as "Dark Moon" for "Blue Moon". Maybe BIAB could provide something like that, that would assist in finding the appropriate style for a tune. Of course, that would not help those of us who approach tunes in non-standard ways. Sometimes, I'll swing a waltz tune, or put a bossa to a song most often played as a ballad.
