Spectral Sonata is an LED cube controlled by a piano. Playing any 3 notes will combine patterns and effects into something unique.
Debuted at Seacompression 2025.
Source code available here. Spectral Sonata runs on Resolume and TouchDesigner. It supports two modes: interactive and "attract mode". It can also be run off an SD card for non-interactive, portable deployment.
LEDs are HUB75 panels with black acrylic, and 3d-printed connectors to organize the panels into a cube shape. All printed parts are available here and can be assembled with M2.5 screws (6mm and 10mm lengths).
