This paper presents a detailed description of an innovative tool for music creation that merges sound and light through a unified system. By leveraging the Tonnetz approach, cellular automata, and embedded electronics, the project offers users an intuitive platform to explore musical harmony and synesthetic experiences. Key features include real-time synchronization of sound and light, the implementation of scales and chord progressions, and the integration of web-based control for multi-unit management. This tool aims to democratize music creation, making complex musical concepts accessible through an interactive, multi-sensory interface.
