Rotate your iPhone vertically, and LightingPad displays the Cue list. The scrolling dial lets you select any of 100 cues. You can set a fade time in the edit box. Touching the Save button saves the current slider positions and fade time to the selected cue, and also lets you name it.
Touching the Go button executes the selected cue and advances to the next one.
Flick the dial or touch the + or - buttons to increment or decrement the selected cue, in preparation to execute it.
Blackout sets all DMX channels to 0.
The settings screen lets you configure LightingPad. The automatic button searches for Art-Net devices and displays them by name and IP address, allowing you to select one to Unicast to. Or you can broadcast to the entire subnet. You can also use the manual button to specify an address.
The switch lets you select whether the slider values are displayed in percent or value.
And, of course, you can transmit on any of 16 universes.
If you are using the latest version of iOS and iTunes, you can save or load entire cuelists to and from your computer. When your device is connected, the available cue lists are displayed in iTunes at the bottom of the device's Applications tab.
