A few weeks ago, I had problems with a Massive X update that Native released without any notice.
Every now and then, Komplete stops recognizing the Arturia package — which is what’s happening now. One moment everything is working fine, and after an update, all Arturia instruments disappear from Komplete Kontrol. It recognizes the plugins but not the Arturia libraries, nor those from Plugin Alliance. I've done everything suggested on the Native Instruments forum, and nothing has worked. All full disk access permissions are granted. Everything was working fine, and suddenly, I can't access the instruments anymore. It's very frustrating to pay a lot for all of this and still deal with constant instability issues.
