OpenMusic Libraries

OpenMusic libraries contain extra tools dedicated to specific purposes.

A default folder for dynamically loadable libraries is created by OM:

You can also add extra libraries folder and register them in OM:

Note: Libraries can also be loaded as “Remote User Libs” (see “Library” window, Menu “File”).

See in the Developer resources for instructions about how to write your own OM library.

Catalog

Most OpenMusic libraries can be found and downloaded from https://github.com/openmusic-project/.

Contact the project admins to get your OM project/library referenced on in this page !

“Standard” libraries:

Esquisse Spectral music / intervallic manipulation tools
LZ Automatic Modeling of Musical Style
RepMus The lengendary library from the Music Representations team
Profile Library for the Control of Melodic Profiles
Alea Aleatoric tools
Chaos Dynamic systems library
Situation Constraint programming

Sound synthesis and spatialization:

OM2Csound Generation of Csound scores and orchestra. External control of Csound synthesis.
OMChroma High-level control of sound synthesis using Csound (requires OM2Csound).
OMPrisma Control of sound spatialization and spatial sound synthesis (requires OMChroma and OM2Csound).

Connection to IRCAM Sound synthesis and spatialization technology:

OM-SuperVP Control of the SuperVP phase vocoder for sound analysis and processing.
See also this release (with Ircam Forum subscription) including SuperVP kernel
OM-pm2 Control of the pm2 engine for sound partial-tracking analysis and additive synthesis.
See also this release (with Ircam Forum subscription) including pm2 kernel
OM-Diph Generation and execution of Diphone scripts for sound analysis and concatenative synthesis.
OM-Chant Control of the Chant syntehsizer.
OM-Spat Generation of spatial sound scenes and spatialization using an offline Spat rendering engine.
