With Light’J, you control your spots as intuitively as never before. Light’J offers you the feeling of a modern app and the various control options of a classic light console. The communication with your light effects is realized via the Eurolite freeDMX interface, which is obligatory. Control colors, strobe effects or the brightness of your spots with Light’J – you can even control the movement of moving heads. Gobos, prisms and other moving head effects can easily be used with virtual faders. Fog and other effect machines can also be integrated. Generate cues to save scenes and to call them up again at any time. You can combine several cues to quickly and easily program chasers. A well-thought-out group feature allows you to control multiple devices simultaneously. Save multiple shows for different setups and stay as flexible as you want. In-app-purchases give you the possibility to also export your chases and cues and to share them with others or use them with other devices. You can also have an unlimited amount of chases or cues and add a master dimmer and a multiplay function. Even though Light’J has been optimized for Eurolite products, you can run all spots of popular manufacturers with it. Only requirement: the spots must be able to be controlled with DMX. You can assign spots, which have not already been added to the database (300 spots by now, June 2017), very easily within a few minutes.
