## What it is
Scribbletune is a JavaScript/TypeScript library for generating music programmatically using simple string and array patterns for rhythms, melodies, and chord progressions. It exports MIDI files, plays live in the browser via Tone.js, and includes a CLI for generating MIDI from the terminal.

## Use cases
- generate midi files with javascript
- create chord progressions programmatically
- make music in the browser with web audio
- generate melodies from scales and patterns
- export midi clips for ableton live
- generate drum and riff patterns from the terminal

## When to choose
- you want to compose music or generate MIDI programmatically in JavaScript or Node.js
- you need a simple pattern language for rhythms, scales, and chord progressions
- you want to prototype musical ideas quickly and import them into a DAW

## When to avoid
- you need real-time audio synthesis on the server rather than MIDI file generation
- you want a full GUI music production environment rather than a code-based tool
- you need the companion VST3/AU plugins, which are closed-source
