This project is a musical instrument that invites users to dive into a world where light and touch shape sound. By interacting with knobs and light sensors, players can manipulate sound in unexpected ways. The complexity of cross-mapped sensors means each twist or shadow alters the music, making every interaction a discovery. Housed in a wooden box, its design adds mystery, inviting curiosity about the hidden connections that influence the soundscape. It's an exploration of how indirect inputs can create a rich, dynamic auditory experience.

How does it work?

At the heart of this device is a pulsar synthesizer, which generates complex rhythms and textures. This signal is then processed through a bit crusher and wave shaper, adding depth and character to the sound. The user interface consists of four knobs and seven light sensors, intricately mapped to various synthesis parameters. Each knob is not limited to controlling a single parameter but is instead linked to multiple aspects of the sound generation process. All components are enclosed in a wooden box, concealing the wiring and electronics, which also adds an element of tactile engagement, as users must navigate the interface by touch and sight alone.
