Forgive my ignorance but "In the multitrack drum loops for each song or style, there are usually about 50 loops, intros, outros, verses, choruses,bridges, fills, so it is very easy to construct a full song with custom drums and have them in 7 piece multitrack form."
Are these files you're referencing BIAB loops and files or are they third party product?
Does " 7 piece multitrack form." meaning each drum,hi-hat, tom occupy an individual track in RB or another DAW or a drum kit mixed to an individual stereo file on a single track in BIAB?
My understanding of loops is ... well ... a misunderstanding.
