Patching a batten or ‘rail’ fixture to make use of all its capabilities can only be done by creating individual colour mixing channels for each cell, which can be very greedy if channels are limited in some way. My thought is generic conversion software to patch the batten as a single virtual moving light channel and create effects on it as non-intensity parameters. For instance Pan could govern the position an intensity beam along the batten with Tilt determining the width of the beam. Certain intensity and colour pattern effects could be achieved with Gobos, all under much closer control than the ‘Macro’ choice offered by some battens using a reduced DMX count.
