Lol, we’ve been waiting for this for years! EZKeys was one of the very first virtual instruments I ever purchased. I can’t remember how long ago that was. Since then, I’ve acquired Superior Drummer and now EZBass that make EZKeys look positively antique in its functionality and GUI. It’s well overdue an update but Toontrack refuse outright to say anything about it because this has been discussed in another thread which was actually 5 years old and there wasn’t a single word from the developers.
It would be crazy of them to have abandoned it but don’t hold your breath.
