Hey all,
DUNE doesn't seem to load in Mixcraft 5 (latest build). It detects it, but when you select it nothing happens. If I remember correctly I had the same problem with X-Poly.
You can download the demo from http://www.acoustica.com/mixcraft/download.htm.
I can't find the details but I think Mixcraft supports VST2.4, Fxpansions Geist is working perfectly in there and thats a pretty new VST as well...
