public class MusicPartControl
extends Object
implements MusicPart
This class provides an implementation of the ExtendedAudioSpec interface for dealing with specific charactertics of the parts of the MusicMedia.

Currently any actions on the part do not reset the MusicMedia with which they are derived from - any changes that are made to a part are only active for an unpredicatable period of time as they do not interact on the Media object itself.
