Groups - Introduction
The GROUP key is used to record and recall Groups. Groups are used mainly for selecting lights, but
may also be assigned to masters where they function like traditional intensity submasters.
You can store channel combinations into groups. The difference between a group and a Preset is that a
group does not necessarily need levels for the channels involved, only the channels selected are stored
regardless of how many other channels are active. Groups also do not contain moving light attributes.
Any currently selected channels and levels are stored in a group, under a single number and name.
