It would seem the Eventide plugins don't appear in DP9 either. Unless of course, I should've installed the 32bit files too? I am running Windows 7 Enterprise 64bit.

Hi wilkinsi-

The plug-ins should work in DP9, since DP9 supports AU on OSX and VST on Windows. First, make sure you are running the 64-bit version of DP9. Then, in your audio plug-in preferences, select "Additional VST Plugin Folders", and add the following folder: C:Program FilesCommon FilesSteinbergVST2. Let me know if that does not solve your issue.

Best,

Tom
