Howdy,

I just finished building a couple of CV monitors per Ken's .jpg and they are 
great. You can really get a little light show going with one on each spare 
output of your VCO's! I recommend all you LED freaks build at least one to 
fiddle around with. I used a Bi-Color LED and mine actually lights Red for 
pos (+) and green for neg (-) with yellow in the middle of the spectrum. Fun 
little additions to an already exciting playground. Thanks Ken,

Thomas White

same time - all that changes this morning though...
