I'm using VST3 in my current project (DJ app) but it's all handled on the c++ side, I didnt need to have access to it from BlitzMax.
I think you may have a few issues wrapping VST, for a start you need modal loops for the GUI windows, so you can expect to need at least some extra C/C++.
Chris C made quite a bit of progress into wrapping VST at one point (I have the source somewhere on another machine), but I havent seen him about for quite a while now, and dont know how he'd feel about sharing it.
