Musical Spirograph Turns Geometric Art into Generative Sound

The application allows users to manipulate the physics of virtual rotors, supporting up to three drawing arms that dictate both visual output and auditory rhythm. Each time a point crosses a ring, the system triggers a note, creating complex polyrhythms based on the user's chosen scale. With six synth presets and adjustable BPM, the platform offers enough technical depth to move beyond a simple novelty, allowing for nuanced control over quantization and pitch across two octaves.

While the current sound engine suffers from occasional clipping and lacks native MIDI export functionality, the utility excels as a creative sandbox. It bridges the gap between classic childhood geometry sets and modern generative synthesis, providing a tactile way to experiment with algorithmic patterns without requiring deep programming knowledge.
