When you first start ViewMaster, it will automatically detect any NDI sources and display the first nine it finds. Each video source is displayed with it’s name below it, and stereo audio meters to the right.
To change the source displayed in each window, click the “Locked” button at the bottom of the screen. The source names will change to dropdown menus, allowing you to choose NDI sources for each window. When you’ve finished setting up sources, Press the “Lock” button again.
These settings are saved, so if ViewMaster is restarted the correct sources will be shown.
