Selector LEDs 

For example, let us just consider the first Selector LED, which represents step 1 and step 9.  If the drum 
is  off  in  both  step 1  and  step  9, then  the first  Selector  LED will  be  off  regardless  of which  half  of the 
measure you are editing.  The chart below describes the state of the Selector LED for each scenario.
