# Note Track Access

All MAXWrapper objects can have one or more note tracks assigned to them.

These note tracks are visible in Track View as children of the MAXWrapper object.

Note tracks provide a way for plug-ins to attach data to any 3ds Max object in a scene, such as nodes, materials, modifiers, controllers, etc., that is permanently stored with that object in the 3ds Max scene file.

This data is stored in note keys, and a note track can contain any number of note keys.

The structure of note tracks is similar to the structure of key-able animation controllers.

A note track is an instance of the class, and has a property called keys .

The value returned by accessing the keys property is a MAXNoteKeyArray .

The MAXNoteKeyArray contains the note keys.

The keys themselves are accessed as if the MAXNoteKeyArray was an array.
