OpenMusic Libraries
OpenMusic libraries contain extra tools dedicated to specific purposes.
A default folder for dynamically loadable libraries is created by OM:
- In OM 6.12 or earlier: within the OM application directory (OM 6.xx/libraries/)
- In OM 6.13 or newer: in your home directory (~/OM/Libraries/)
You can also add extra libraries folder and register them in OM:
- Create a directory “Libraries” (or any other name) somewhere in your computer (but not in the OM directory!).
- Put your own libraries in this folder
- Register this directory in the OM Preferences (“Libraries” tab, external user lib directories).
- If necessary, use the menu item “File/Refresh Libraries Package…” on the Library window in order to update the libraries list.
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.
