colour organ in UE4.26
This project was based on Alexander Wallace Rimington’s,
A New-Art: Colour-Music, and made utilizing
Arthur Barthur’s Fancy Audio Blueprints.
The intention of this project was to replicate Rimington’s colour music theory within Unreal Engine.
To set up the light orchestration, I backlit a semi-translucent screen (plane), arranged lights to have five rows of seven (5 octaves, each with a scale of 7), and then assigned light colors as the ROYGBIV spectrum.

There is certainly a better way to do this, but what worked for me at the time was putting a point light into the world, grouping it with a blueprint I made, then copying and pasting this grouping 35 times, repositioning and relabeling them all appropriately.
I remember having issues with implementing a point light directly into the blueprint actor I created, but with this setup of mine I could individually assign the blueprint actor to a specific “Point Light Ref,” assign what frequency slot the point light should listen to, and simply assign the point light’s color directly in the world.
