I don't support the idea of adding ARA support in Band-in-a-Box.
I DO support the idea (+1) of adding ARA support in RealBand.
ARA support so the user can utilize Melodyne doesn't make much sense in BiaB but would be a very useful asset to RealBand.
I view Band-in-a-Box as a tool to develop a song sketch, music education tool or accompaniment tracks.
ARA support in RealBand makes more sense to me because RealBand is marketed as
a fully-featured and powerful music arranging, sequencing, and digital recording program
by PG Music.
