I think what will save it is ReWire, this will be implemented soon, that will mean you basically operate from your 64bit DAW using BBMac to create the tracks on the fly, just like how RealBand works in Win, it uses an app in it's folder bbw2.exe that runs invisible in the background, it is just basically the biab app.
RealBand calls on bbw2.exe to generate up the tracks for RealBand.
Having ReWire this will let BBMac play along with your DAW start/stop/pause/continue/loop. This way your are not putting all the load onto 32bit BBMac. Win has RealBand but it has nothing on a good 64bit DAW.
I think BB would have to be the ReWire master as it don't start play instantly.

Then you can do MultiRiffs

You can load the Exported Chord Sheet video in the DAW or when they implement the drag n drop midi BB Chord Output midi file with chord markers in it this will give your DAW a Chord track and any tempo map before dragging in the audio RTs RDs.
