when opening cubase Pro version 13,0.30 ,my Arturia V-2 plugins are going to the back list..upgraded my auturia plugins..
If by “Arturia V-2 plugins” you mean V Collection 2, it wouldn’t surprise me if plugins that ancient were only 32-bit, which haven’t been supported in Cubase at least since I started using Cubase (at V9.5). You could try with a 32-bit to 64-bit adapter (like jBridge) maybe, but better would be to upgrade to newer versions of the Arturia software – they’re currently at V Collection 11.
If you mean something else, perhaps you could be more clear about your specifics. For example VST2 or VST3 versions of the plugins, and, if VST2, are you on an Apple Silicon Mac (might be able to do that in Rosetta mode perhaps, but not natively???)?
