public class Track extends Object
Track occupies a middle level in the hierarchy of data played
: sequencers play sequences, which contain tracks,
which contain MIDI events. A sequencer may provide controls that mute
or solo individual tracks.
The timing information and resolution for a track is controlled by and stored
in the sequence containing the track. A given
is considered to belong to the particular
maintains its timing. For this reason, a new (empty) track is created by calling the
method, rather than by directly invoking a
Track class provides methods to edit the track by adding
MidiEvent objects from it. These operations keep
the event list in the correct time order. Methods are also
included to obtain the track's size, in terms of either the number of events
it contains or its duration in ticks.
