Modular Synth Panels

WOW, looks fantastic. I'm a bit unclear as to whether some of the  
green circles are for LEDs, or switches, or pushbuttons along the left  
edge (RANDOM INPUT down through CLOCK THRU RATE). Also, I noticed that  
the CLOCK THRU and CLOCK IN labels are centered above the jack, but  
EXT LOAD, EXT RANGE, and RANDOM INPUT are not. Is that because some  
are switches and some are LEDs?
