Realband does support this and you probably have it included with your BiaB install if you are on Windows.
May want to try Realband, then post RB specific questions in the Realband forum.

/plus the RB default behavior is to play the same RTs each time until you tell it to regenerate something, so learning a part with the exact same backing tracks acts more as expected

RB is more like a standard DAW than BiaB, but retains the generating capabilities.


I do not work here, but the benefits are still awesome
