OpenMusic Libraries

The OM folder includes a "library" sub-directory containing a number of dynamically loadable libraries. The libraries contain extra tools dedicated to specific purposes.

You can also add your own extra libraries and load them in OM:

Notes:


- How to write my own library?

See "Writing user libraries" in the Developer resources section for instructions about how to write your own OM library.
