I managed to get the colour timeline controls working pretty well (still some finessing to do) so I thought I’d try a little experiment and feed the Hue, Saturation, and Lightness from the colour being generated in the colour timeline to a MIDI output, creating musical notes depending on the levels. There is a grand tradition of linking colours and musical pitch (see Isaac Newton’s 1704 book Opticks) so this provides a way of playing about with this data.
