242 Development 8/6

Managed to split the notes according to their octave. this allows no overlapping (vertically) of notes. This makes it easier to read. 

Also added a check for Note On and Note Off functions and only draws on Note On functions. This stop the score doubling up.

I also have begun to play around with how it be displayed visually. This one is with low opacity rects rther than ellipses. The overlapping effect is really nice.
