Greetings,
Most of the komplete effects and synths are vst3 these days, but a few remain vst2. Absynth, Reaktor, Battery, Guitar Rig and maybe 1 or 2 more.
Will these be updated to vst3 any time soon?
I ask as Cubase 12 won't scan the the folders they are installed in. I presume ill be able to move them to another folder (native access will still read the original folder I guess) as a work around for now. Things might get a bit iffy with updates etc in the future. But it will do for now I guess.
I do know steinberg are dropping vst2 going forward, so hopefully there is a plan to update them to vst3. I'm rather fond of absynth in particular, but use all the others a lot too.
