RGB-Box Scope:

  A window of configurable size consisting of a  square.  The  square  will
  flash  in  time to the first three tracks of the module being played. Any
  additional tracks will have no effect on the RGB-box.

  The colors are chosen so that the first  track  controls  the  red  color
  value,  the  second  track  the green color value, and the third the blue
  value. Each note in a given track retrigs the corresponding color  value.
  The higher the volume, the brighter the color.
