OpenMusic (OM) is a visual programming language designed for music composition. Visual programs (called "patches") can be created by connecting graphical modules together, corresponding to musical objects or data processing functions.

OM offers you a complete freedom in programming, including text programming via the Common Lisp language. A large numbers of specialized projects and libraries are available for specific applications (mathematical tools, sound processing and synthesis, etc.)

This documentation is divided in two main parts :

• A complete user manual describing the use and features of the evironment
• A "quickstart" tutorial with video demonstrations
