I don't want to knock ANY ideas, I suggest ways it could be done or find a workaround until it's done (or not) but all these things are why the BiabPlugin was made. It would help if you could suggest features in the BiabPlugin forum that's you thinks needed or if you need the complexities of Biab then maybe a VST to sync Biab as a slave to your DAW.
There was talk for yearssss about a new reprogrammed 64bit RealBand that works like Biab generating to RAM with more tracks.
That never came around so ReaTrak was made to integrate Biab (and now the Plugin) with Reaper as the scripting allows you to add features "today" without going to the wishing well year after year.
