Hi Jeffrey,
It should support 64 and 32 bit for all formats. Please make sure Studio One is pointing at the c:Program FilesCommon FilesSteinbergVST2 directory to see the 64 bit plug-in, or that you've installed the 64 bit plug-in in your proper search directory for Studio One. Note that the 32 and 64 bit plug-ins cannot be installed in the same directory.
