User Buttons
These buttons can be assigned to a number of functions, including ME and key selections, custom control, and memories. The number and position of the buttons on the control panel depend on the model of your control panel.
If a button is assigned to an ME, aux bus, MiniME™, MultiScreen, or chroma key, you can press and hold the button to be able to select a different ME, aux bus, MiniME™, MultiScreen, or chroma key from the key bus. If the user button is assigned to an Aux, it will allow you to select a different Aux.
