So far I haven't found any problems with VE Pro 5 and DP8. And indeed, bouncing with the Audio/Event Input plugin seems to work flawlessly. Mind that all affected tracks (VE Pro Server Interface plugin track, its assigned VE Pro Audio/Event Input plugin tracks and their respective audio/MIDI tracks) need to be selected or bouncing will indeed just result in silence. It is still required to set the Audio Plug-ins preferences to All Plug-ins in Real-time for proper functionality, much like with DP7. All in all a rather major improvement.
EDIT: I was a bit premature in my conclusions about bouncing. It only happened to work in my one test session, but I can't get it to work again now. Apologies.
