Fader Groups Traverse Banks
A fader or channel switch may be made into a Group Master. Activating the control (moving a fader, pressing a button) results in data being sent for that control, and all members of the group.
A Group Master may have members that are in different Banks than the Group Master. For example, Fader 8 can be a Group Master, and "Fader 9" can be a group member.
If no Expanders are present, it is easy to see that Fader 9 is really the first fader, but in the second Bank.
Moving Fader 8 sends data as if Faders 8 and 9 were moved. You would not see Fader 9 actually move, because Bank 1 is selected while Fader 8 is being moved.
Group Members are Automatically Scaled
When a Group Master is moved down, the group members values are scaled so that all the faders reach the bottom at the same time.
When the group master is at the top of its throw, the current position of the group members are taken as their starting position.
Any movement of the group master downwards moves the group members down from this starting position.
If a group member is moved individually, the next time the master is moved, the group member will first immediately jump down to its scaled position.
