/**
 * A hardware or software device that plays back a MIDI
 * <code>{@link Sequence sequence}</code> is known as a <em>sequencer</em>.
 * A MIDI sequence contains lists of time-stamped MIDI data, such as
 * might be read from a standard MIDI file.  Most
 * sequencers also provide functions for creating and editing sequences.
 * <p>
 * The <code>Sequencer</code> interface includes methods for the following
 * basic MIDI sequencer operations:
 * <ul>
 * <li>obtaining a sequence from MIDI file data</li>
 * <li>starting and stopping playback</li>
 * <li>moving to an arbitrary position in the sequence</li>
 * <li>changing the tempo (speed) of playback</li>
 * <li>synchronizing playback to an internal clock or to received MIDI
 * messages</li>
 * <li>controlling the timing of another device</li>
 * </ul>
 * In addition, the following operations are supported, either directly, or
 * indirectly through objects that the <code>Sequencer</code> has access to:
 * <ul>
 * <li>editing the data by adding or deleting individual MIDI events or entire
 * tracks</li>
 * <li>muting or soloing individual tracks in the sequence</li>
 * <li>notifying listener objects about any meta-events or
 * control-change events encountered while playing back the sequence.</li>
 * </ul>
