with current versions of controlP5, knobs can only be adjusted by either moving 
the mouse along the x-axis (default) or y-axis (use 
setDragDirection(Controller.HORIZONTAL or Controller.VERTICAL)). changes when 
moving the mouse in both directions at the same time have been removed due to 
conflicts with other features.

suggestion because i think it is important to set the value when moving mouse 
in x AND y-axis:

calculate angle between mouse position and center point of the knop. set the 
value of the knop according to that angle. This should not conflict any other 
feature.
