Hi,
which part are you having trouble with?
The installation process itself is to simply extract the .dll file from the .rar you downloaded, and placing it in your VST folder. If you use any other plug-ins, you should have this folder selected in the “Plugins” tab on the Preferences dialog (Setup -> Preferences).
To make the plug-in show up in Podium, you have to either update your plug-in database (select “Update and Load Plugin Database” from the Devices menu on the project start page) or import it manually (by selecting “Import Plugin…” from the same menu).
How to actually set it up on your tracks so that it works correctly is a different matter… I haven’t used this plug-in, so I’d have to look into it.
Let me know if you need more help! 🙂
