Oddly enough I found a part of this works for me - I entered a series of plug-in names (faithfully!) in the whitelist file, putting the 32 zeros beneath each of them. Unfortunately none of them were updated to =0" in the defaults file.
But… when I opened Dorico again, several of them were working as VST’s, including Play, Addictive Drums, BFD2 and some NI synths. I haven’t tested them thoroughly with multiple channels etc., but an initial test shows no problems.
As I have Cubase 8.5 installed and those VST’s work perfectly there, I’m guessing that the necessary codes etc. were already in the system and somehow I’ve opened them up for use in Dorico.
