Question

Guys, one question, is the VST and AU and Rewire Support expantion from my studio one 3 going to with ver 4 or i must buy new one?

Answer 1

Your VST add-on will work with Studio One 4 Artist.  If you need to re-install it, you can do so from Studio One>Studio One Installation within the program or from your my.presonus.com account under My Products>Add-ons.  If you download it from your account, you can simply double-click it to install.
