Yes it should have the same basics.
The original idea was to be able to add other instruments to a recorded studio session rather than have auto-accompaniment in a DAW.
I said the only way to get all the Biab features of the mother program in the DAW is just have a Biab sync VST that you load in your DAW and it syncs the main Biab app to the DAW playback and you don't have to wait for renders.

If the Plugin is made to play back the wma/wav RT RD files directly it would be quicker to get the tracks playing in the DAW rather than waiting for Biab in the background to render them down to wav, and also this will give the exact same tracks as in Biab if you freeze them and open the SGU in the Plugin.
So if you open a frozen SGU from Biab it will play exactly the same instantly in the DAW playing the exact same sections. Changing, adjust any section or adding more instruments would be instant without having to re-render all new wavs.
