Yes, thanks Anderton,
Have used the buzz shell for many years and it works with about anything to bring dx into a vst world.
One problem I had was with the dx wrapper, not the dxi wrapper, and this problem would probably be in relation to how much antiquated software you have on your drive.
The dx wrapper does a great job of getting the registry dx entries and porting them for use into any DAW supporting vst. Problem is that so many other non music softwares have a bunch of dx plugs, word processors, graphics programs, etc, etc. You can be buried in a wash of dx files from your email client or whatever. The music stuff is there, but sometimes like a fishing trip through the maze to find what you are looking for.
I stuck with the dxi plug because not a lot except the music is there. Allows you to use TTS-1 in something like Studio 1. Reaper has retained dx/dxi status so Cake dx plugs are there in Reaper native, as well as any other programs that are not blocked by Cake for external read.
