Typically an applications uses either the NoteChannel or a movie to playback QTMA data. A NoteChannel corresponds to a part in the MusicComponent that it is using (as dictated by the NoteRequest used to create the NoteChannel). <P> The NoteAllocator keeps an indexed list of each unique MusicComponent that is in use by the system. The Application can call the NoteChannel.getIndexInfo() call to get the index within the NoteAllocator that can then be used to retrieve the MusicComponent that the NoteChannel is using. (There is also a call NoteChannel.getMusicComponent() that will return the actual MusicComponent instance). <P> There are three calls that require a part number to be known (ie. this is the part number within a MusicComponent that a particular note channel is using), and in those cases the application can use the NoteChannel.getPartInfo() to return that part number. This can then be used in the MusicComponent calls that require a part number to be supplied.<P><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A
