If you are running Gig Performer on a Windows machine, your plugins can be installed in arbitrary locations specified by the plugin developer and/or modified by you. In either case, if some of your plugins do not show up in Gig Performer, you will need to tell Gig Performer where it should look to find your plugins.
Please also be aware that Gig Performer only supports 64-bit VST and VST3 plugins.
Step 1: Click on Windows : Plugin- manager to open the plugin manager
Step 2: When the Plugin Manager opens, it will display a list of all plugins that were found. If a plugin is displayed in green, it has been validated. If a plugin is displayed in red, it has not been validated and is consequently unavailable. Note that all 32-bit plugins will show up in red as they cannot be used. Click on the Manage… button at the bottom left of the Plugin Manager window. Then select the Set VST folders for scanning menu item.
Step 3: You will see a dialog containing the folders that Gig Performer already knows to check. Press the + to specify another folder. You can do this as many times as necessary.
Step5: Navigate to and then select the folder where your plugins are located and press OK
Step 6: Click the Scan… button and select Rescan failed plugins or Rescan all plugins
Step 7: Gig Performer will look for your plugins in the new locations and when complete your plugins should now be available.
