I'm just hoping for JJJ's BiabVST idea, this will give you Biab right in any 64bit DAW along with MultiRiffs, this way you can do it all directly in the DAW, start to finish.
You can even have other studio or live recordings and the BiabVST will generate up any extra instruments to the same tempo map in the DAW.
This will be even better when the Audiophile version moves to 24bit audio quality and multi stem RealDrums to give full mixing control of the drums.

So the current Biab will stay unchanged for those that use it for accompaniment, songwriting and as a learning tool etc...
While those that need it for high quality studio track creation will use the BiabVST.
