When I say "At the end of the day all the PLUGIN needs is the wav instructions." that is how it needs to work so it will open a frozen SGU from Biab and be exactly the same with same sections.
If I can open a frozen multistyle SGU in Reaper then the Plugin can be made to do the same thing giving the user the same as the main Biab app in their DAW.

You can see instrument changes in Reaper that you can't see in Biab:

It's the same issue with RealBand, though it loads all the frozen RealCharts but not the wav data of a frozen Biab SGU with all Utility tracks:
