OpenMusic

From Wikipedia, the free encyclopedia

OpenMusic (OM) is an object-oriented visual programming environment for musical composition based on Common Lisp. It may also be used as an all-purpose visual interface to Lisp programming. It forms part of a package of software offered by IRCAM which also includes Diphone Studio (for sonic morphing) and Modalys (for physical modelling synthesis).

[edit] History

OpenMusic is a descendant of PatchWork, a computer-assisted composition environment for the Macintosh first developed at IRCAM in the early 1990s. Versions of OpenMusic are currently available for Mac OS X (currently PowerPC only, though an Intel port is under development), Windows and Linux operating systems. The source code has been released under the GNU Lesser General Public License (LGPL).

[edit] 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 and the compositional use of fractals.
