I got lucky and was able to add the most needed plugins to the whitelist text document file, so now they show up in Dorico. I left a bunch of my UAD, and others, out for now (may add them later). Hopefully you guys can help the OP too!
May I suggest using whatever method Cubase/Nuendo use that automatically finds all your plugins as long as the paths are set correctly in the Plugin Manager? I understand you’re trying to keep Dorico as streamline as possible. But, at the same time, I feel like this is an inconvenience placed on the users, that doesn’t even save you any trouble since I’m sure this has to be one of the most asked question by new users (at least I assume that given what’s needed from the user in order to make VST 2 plugins work in Dorico).
Unfortunately, for whatever reason, there’s still a LOT of plugin developers not jumping on the VST3 protocol. Please don’t penalize your users because of them .
