You can install Cuelux on every pc that you would like.The only thing that unlocks the software to use it with a visualiser or a real fixture is the DMX dongle.
All you need is the software (here to download) the Cuelux USB adapter (CueCable) and lights to operate.Optional is a Midi desk.
What visulizers will work with Cuelux?I miss the 3D visulisers in Daslight but find Cuelux much better to use, could I use that one?
