But I guess the truth is:
(1) Reason CANNOT support vst.
(2) RE are not vst.
(3) If you want vst use Rewire.
After all PH are clear about that: "if you use reason, you don't need anything else. It is complete. You wanted plugins? We give you REs". That's it.
(This does not mean I like that policy. Infact I don't)
