User story:
As a MxB I want to be able to see where I am in the sequence when setting Sequence Length so that I can use it as a performance tool more easily.
When Sequence Length is pushed the 4 dots of the last step light and the lights for all others are off. It would be useful to see the pink sequencer "cursor" as it steps through the sequence. This would make it easier to time the change of the Sequence Length while performing. It would be especially useful when changing the length if it's a faster sequence or when using a ployrhythm.
