I’m actively using dozens of VST3s in Reason 11 right now. VST3 in Reason 11 is a reality. No idea about the specific issues you’re hitting, but VST3 absolutely works. I’m literally using it.
@EnergyCrush You miss something, Reason 11 currently doesn’t support VST3:
The Rack plugin is a VST3 plugin. And you can use VST3’s in Renoise, when you use a wrapper:
I’ve used this wrapper with Renoise 3.2 on my windows 10 maschine. Works fine with some smaller quirks. Its a workaround, till Renoise support it natively.
