## What it is
Overtone is a Clojure toolkit providing an API to the SuperCollider synthesis engine for designing synthesizers, live-coding music, and collaborative jamming. It includes musical functions, timing/metronome systems, MIDI I/O, OSC support, and integration with visual tools like Quil.

## Use cases
- live-code music performances in Clojure
- design custom synthesizers and effects
- sequence music with metronomes and arpeggiators
- connect MIDI controllers to a synthesis engine
- synchronize visuals with audio in live shows
- query and fetch samples from freesound.org

## When to choose
- you want to program music in a Lisp on the JVM
- you need programmatic access to the SuperCollider engine
- you're doing live-coded or algorithmic music performances
- you want MIDI and OSC integration from Clojure

## When to avoid
- you need a GUI-based DAW for traditional music production
- you don't want to learn Clojure or Lisp syntax
- you need a pure-JVM audio engine without SuperCollider installed

## Facets
- artifact type: library
- maturity: active
- function: audio-processing, sdk, plugin-system
- domain: audio, developer-tools
- platform: windows, jvm, cross-platform
- tags: clojure, supercollider, live-coding, synthesis, midi, osc, music, algorave, audio, linux, macos
