I've just read a little here and there, sounds awesome. I think it'll make reason even more viable than it already was, allowing 3rd party developers to contribute new plugins is all I ever wanted in Reason lmao. They obviously aren't going to just allow vsts and other formats in, but im hoping some of my favorite vst plugins get made into rack extensions....(omnisphere ne1?)
Until now i couldn't justify using reason as a standalone, only rewired because a lot of my investment in my lab has been plugins...which isn't going to be fixed with the addition of rack extensions but atleast there will be more options available in Reason.
