Objects - Factory Boxes
In OM, objects are created and used in patches via “ factory “ boxes. A factory box refers to a class[1] and allows to create instances[2] - exemplars, in other words -, of this class.
- Factories can be connected to the other components of a visual program.
- Their inner editor is a graphical user interface that allows to visualize, edit and manipulate the objects produced by factories. For instance, one can edit a musical sequence in a traditional score editor.
This dual aspect of formalized computation, associated with direct manual interaction on the musical material, is a fundamental feature of OM, which makes the factory box a major patch component.
Factory boxes are accessed via the Classes menu or can be added in a patch
from the Library window.

- Class
A category of objects sharing common properties - characteristics and behaviour. A class specifies the internal structure and behaviour of an object. In OM, it is represented in a patch by a factory box that can produce an instance of a class.
See also : Object, Instance
- Instance
An actual object created at runtime, out of a given class. In OM, more specifically, an object created when evaluating a factory box. An instance can be saved as a global variable.
⤷ SHIFT click on an outlet - especially the first outlet representing the
self, the whole object - of a factory box to materialize an instance.
