Third-party instrument plugins can be used in Serato Studio - they operate much like an Instrument Deck within the Serato Studio interface. 

To load a third-party instrument plugin:

1. Open the Plugins tab within the Serato Studio library panel
2. Click and drag the plugin onto either an already loaded instrument deck (left side of the Serato Studio interface), or onto the Add deck area (right side of the Serato Studio interface)
3. The plugin interface should open in a new window when loaded for the first time, alternatively click the Open / Close button in the Plugin Deck Header

NOTE: While all third-party plugin parameters are controllable within the plugin's interface, automation of these parameters may not be available. See Overview: Automation for more information.
