I'm a iMac (macOS High Siera) user and I use Studio One 3 Artist. I have a big problem. Studio One 3 Artist can not recognize EZ Keys (toontrack) and EZ Mix 2 (toontrack) but automatic recognizes EZ drummer 2 (toontrack). I downloaded programs the same way. I do not see an option to adding . Does anyone else have experience with this? I'm devasted.
