One important thing I left out of my PG BB RB love is the amount of musical information not just in the program itself, but the amount of "musical knowledge" in the musical content itself. You have playing and recordings of the best studio musicians in the world - and hundreds of hours (if not thousands ?) of each. And almost all of it is notated and played back on a staff with color coding. And so, so, so many different styles authored by experts in their musical field....just to separate the usefulness of the program from the human-generated musical recordings and accompaniments underneath...all fitting together like a glove.
