How to install a VST plug-in

A VST plug-in is a DLL file. By default plug-ins are saved to folder

"%programFiles%\Audiodope\Plugins".

Unzip the plug-in and save it to the defined folder. If you want to keep your plug-ins in a folder other than the default you may click Options -> Preferences -> Directories and select a different folder clicking "Browse" button.
After copying the plug-in to the defined folder restart the software to update the list.
