Fixture Patching

Giving each fixture its DMX start address and its profile (personality) in the console, so the control channels map to the right functions. Addresses must not overlap: a fixture using 16 channels from address 1 occupies channels 1 to 16, so the next fixture starts at 17. A wrong profile or overlapping addresses, and fixtures respond to the wrong parameters — pan reacting to a colour fader, for instance.
