The XSplit connection allows you to directly interact with your instance of XSplit to perform changes to scenes and sources.
To interact with XSplit, you would add a Streaming Software Action to your command.
To enable XSplit connectivity, you must do the following:
Start XSplit and navigate to "Extensions" -> "Add custom extension". In the open file dialog that pops up, navigate to your Mix It Up installation folder and select the "Mix It Up.html" file under the "XSplit" folder.
Navigate to Extensions -> Mix It Up to launch the Mix It Up listener. This window must remain open for Mix It Up XSplit interactions to work.
Click on the "Enable XSplit" button.
To test the the feature has been set up successfully, you can click on the "Test Connection" button, which will pop a dialog in Mix It Up if the connection was successful.
