As i have not seen AAX plug ins yet i cant be sure. But it is pretty common to get a PTLE (a non HD session) ware all the plug ins are clipped and all the bus's are red. Your resources will start to turn all red the channels will start to turn red. Its a hint that bad sonic thingies are about to enter the air. And the clients sitting there wondering why you a messing with the mix that they took so long to put together at home. Now it should be even harder to clip those internal plug in bus's. It will also make sure that your session translates from non HD project studio to HD Mix Room as all mixing is done in about the same way in respect to the mix bus across all PT platforms.
