Simple Colour Organ example (59.5kB)
This is a simple opengl plugin based on the 'colour organ' ideas of
people like Father Louis Bertrand Castel and A. Wallace Rimington, where
musical notes are seen as corresponding to specific colours. The plugin is
strictly a visual instrument – it does not output any sound. Instead colour
is displayed when you hit a key, so you can 'play colour' as you would
music. (C++)
