The BBPlugin basically works the same way as RealBand but in the DAW of your choice.
RealBand has C:\RealBand\Data\bbw2_64.exe
that is just Band In A Box running silently in the background that generates up the tracks into RealBand's temp folder.

The BBPlugin works the same way and has bbw4_64.exe running silently in the background generating the tracks up into C:\bb\BBPlugin\SavedTracks.
So you should be able to accomplish all you need using the BBPlugin in Ableton if that's your goto DAW.
There are just so many features been added to the Plugin to let you do all you need right there in your DAW.
I think to get away from stress and frustration it is well worth looking deeper into the BBPlugin.
