What's that
Art-net controller is an Android App that simply sends DMX 512 packets through Wifi following the Artnet protocol and sACN e1.31 (since R08)
This is just an App for testing/focussing purpose but also can be used to play a simply show if your main controller is broken or you forgot it ;-)
This application has been made by a lighting operator for lightings operators so you can expect some of the features on most popular lighting desks:
Submasters, CueLists, Command Keyboard, Playback buttons, Grand Master, etc...
Also (since R05) App is provided with a Fixture Control, to easily control complex fixtures or mediaservers parameters
