The mouse is dragged over a colour wheel and this allows for sounds to combine together as the colours change. There are 12 colours which have got separate volume faders assigned to them. These respond to where the mouse is on the colour wheel.
This is then combined with 3 other volume faders which are dark, bright and light soundscapes. So if the colours that the mouse is hovering over is dark then dark sounds will be produced. This patch shows the extent that colour can be used in creating music. It would probably have the potential for creating complex chords and could be used to create a composiotion by colour.
