Fade to Black
Fade to Black allows you to have one, or all, of the ME outputs fade to black with a single button press. Pressing the button again returns the ME output from black to the previous state.
In an MultiPanel configuration, the fade to black only affects the ME outputs that are assigned to the control panel that the fade to black is performed on, and that fade to black is turned on for. Each control panel has a unique fade to black rate, but which ME outputs that fade to black is turned on for is common across all control panels.
