Musical Spirograph tool allows browser-based generative music composition

Key facts

  • Musical Spirograph generates patterns by moving points along mathematical paths.
  • The tool features six distinct virtual rotors and six synth presets.
  • Users can configure up to three simultaneous drawing arms.
  • The application allows for manual adjustment of BPM and quantization settings.
  • The software is currently limited by a lack of MIDI output functionality.

Musical Spirograph is a web-based application that combines geometric drawing with generative music composition. The tool uses points moving according to mathematical equations to create hypotrochoids and epitrochoids, which trigger musical notes as they pass through concentric rings.

Customization and Features

Users can adjust various parameters to influence both the visual patterns and the audio output. The tool offers six virtual rotors, the ability to use up to three drawing arms simultaneously, and multiple options for tweaking the geometric designs. For audio, users can select from six scale options, customize individual notes, and choose from six synth presets. Additional controls allow for adjustments to quantization, BPM, and the expansion of rings to cover two octaves.

Performance Considerations

While the tool provides a functional generative experience, it has technical limitations. The sound engine is prone to audio artifacts and clipping. Additionally, the current version of the tool does not support MIDI output for controlling external instruments.
