So the resolution was to use the "...export the tracks, (flat, centred etc), from BIAB & insert them into the project"
Which would mean, the conclusion is don't Use the BIAB-VST to insert the tracks.

I have to acknowledge the shortcomings of the BIAB-VST. After 5 years I feel I understand these as much as anyone else. However, I have never seen this exact problem as described in this thread. The RTs have never sounded "different" based on how they are generated or how they are transferred to the DAW. So I am wondering if this is a "Mac" issue?

Is the BIAB-VST different for the Mac versus a PC?
