Collaborative Programmable Music.

Overtone is an Open Source toolkit for designing synthesizers and collaborating with music. It provides:

  • A Clojure API to the SuperCollider synthesis engine
  • A growing library of musical functions (scales, chords, rhythms, arpeggiators, etc.)
  • Metronome and timing system to support live-programming and sequencing
  • Plug and play MIDI device I/O
  • A full Open Sound Control (OSC) client and server implementation.
  • Pre-cache - a system for locally caching external assets such as .wav files
  • An API for querying and fetching sounds from http://freesound.org
  • A global concurrent event stream

Quick Start

Installation

    # Install lein2
    # https://github.com/technomancy/leiningen

    $ lein new insane-noises

    # add the following dependencies to insane-noises/project.clj
    # [org.clojure/clojure "1.5.1"]
    # [overtone "0.9.1"]

    $ cd insane-noises
    $ lein repl

Making sounds

    ;; boot the server
    user=> (use 'overtone.live)

    ;; listen to the joys of a simple sine wave
    user=> (demo (sin-osc))

    ;; or something more interesting...
    user=>(demo 7 (lpf (mix (saw [50 (line 100 1600 5) 101 100.5]))
                  (lin-lin (lf-tri (line 2 20 5)) -1 1 400 4000)))

Detailed Instructions

For a more detailed set of setup instructions (including details specific to Windows and Linux) head over to the Overtone wiki installation page

We maintain documentation for all aspects of the system in the project wiki, you'll find tutorials and examples on topics such as synthesizing new sounds from scratch, live-coding and generating musical scores on the fly. If you see anything missing, please feel free to add it yourself, or hit us up on the mailing list and we'll sort something out.

Community

Mailing List

We encourage you to join the mailing list to see what other people are getting up to with Overtone. Use it to ask questions, show off what you've made and even meet fellow Overtoners in your area so you can meet up for impromptu jam sessions. All we ask is that you be considerate, courteous and respectful and that you share as much of your code as possible so we can all learn how to make crazy cool sounds together.
