I'm using the very latest Digital Performer 8.05 and VEPro 5. I use them on the same machine. I also use the Event Processor - so I have one instance of VEPro as a plugin, and about 18 Event Processors. The metaframe is mostly populated with Kontakt 4. All of the tracks play flawlessly.
I am only able to bounce-to-disk instruments/midi tracks that are assigned to VEPro's midi channel 1. None of the Event Processors will successfully bounce. Before updating to VEPro 5.2.12800 BTD would work properly across all channels.
Thanks - Robert
