Why do you do this to me??! 

Guys
The beauty of the Nob is there is no setup.  All you have to do is click on a virtual control with your mouse, make sure your nob is set for vertical/horizontal... knob or slider and change to your heart's content.  
 
Move to another virtual control  - lather, rinse and repeat.
