OpenMusic is the last in a series of computer-assisted composition software designed at ircam. Versions of OpenMusic are currently available for Mac OS X (PowerPC and Intel), Windows and Linux. The source code has been released under the GNU Lesser General Public License (LGPL).

A typical OM program or 'patch'.

Programming in OpenMusic

Programs in OpenMusic are created by connecting together (a process known as 'patching') either pre-defined or user-defined modules, in a similar manner to graphical signal-processing environments such as Max/MSP or Pd. Unlike such environments, however, the result of an OpenMusic computation will typically be displayed in conventional music notation, which can then be directly manipulated, if so required, via an editor. A substantial body of specialized libraries has been contributed by users, which extends OpenMusic's functionality into such areas as constraint programming, aleatoric composition, spectral music, minimalist music, music theory, fractals, music information retrieval, sound synthesis etc.
