Yep thanks, I did find out about the update from u-he through KVR after I replied to your post above. It took me a bit to work out that I needed to delete both older versions of the diva plug from my users and from the system library locations before installing the latest version before it would work..
Hopefully cakewalk will come through with something for Z3TA.
Sorry, I know nothing about the Waldorf issue so cant help you out there.
