A stroke (line) in the
Sketch Window will sound the contents of the motive of the same color.
There are only eight colors in the color palette. However,
this does not mean that you can only have eight different Melody or Percussion
Windows. In fact you can re-use melody colors as many times
as you wish, having multiple melodies of the same color.
In the event of there being multiple melodies of the same
color, a stroke in the Sketch Window will play back the musical material of
that melody to which the beginning of the stroke is closest in proximity.
