The Arturia VST3 issue for the V Collection has been posted now 2-3 times in this forum.
The workaround is to uninstall and then install only the VST 2 versions of the modules. This takes maybe 10 minutes to do.
The VST 2 modules SOUND IDENTICAL to the VST 3 modules, and work just fine.
When the issues are resolved, you can then go back and install the VST 3 modules again.
It is NOT a big deal, as the VST 2 synths work fabulously.
The current sale price for the Arturia V Collection is a GREAT deal, for a bunch of REALLY nice vintage synths, done very nicely.
The Moog Modular V is my favorite synth, outside of Kontakt.
