It Bug's me.

People get stuck using just BIAB and are a bit frightened of Realband.

Say in Kontakt you have a strumming guitar and you have different tempos, BB/RB won't send that info to Kontakt. If you want to make up your own track in EZKeys/Drummer you can't.
That's just a few examples.
It should be a good fix in BB and RB for the long run, it's a Standard thing in other audio programs, I don't think you will get anyone at all complain when they fix it, it will just open up a lot more possibilities.

So I will just throw a few more coins in smile
