More tracks ? BB will end up becoming a DAW, we wouldn't want that ?
If the VST Sync was working you could easily add more tracks with VSTs like Temper as you just drag the tracks in from the drop station.

A lot of difficulties arise when people buy Biab not realizing there is RB as all the Marketing is all about "BB" so they have spent all their time learning BB and by then it is too late to drive a manual car so they are stuck with only being able to drive an auto.
