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 the clojure-cli tools
# https://clojure.org/guides/getting_started
# Create a deps.edn file with a minimum
# {:deps {overtone/overtone {:mvn/version "0.10.6"}}}
$ clojure
$ (use 'overtone.live)
# Or install leiningen
# https://github.com/technomancy/leiningen
$ lein new insane-noises
# add the following dependencies to insane-noises/project.clj
# [org.clojure/clojure "1.9.0"]
# [overtone/overtone "0.10.6"]
$ 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)))
Linter (clj-kondo)
Run overtone.linter/emit! to emit clj-kondo configuration.
Do not commit the generated files, it's a bunch of data.
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.

Introductions
Head over to Vimeo for a fast-paced 4 minute introduction to live-coding
with Overtone to see what's possible
For a nice overview of the basics of creating and playing with
synthesized instruments in Overtone checkout Philip Potter's 20 minute
workshop:

Chris Ford also delivers a beautifully paced introduction to fundamental music
concepts from basic sine waves to Bach's Goldberg Variations with live examples throughout:
