Usage

From source file:SoundPlayer.java

        // That is, to send events to a Synthesizer at the right time.
        sequencer = MidiSystem.getSequencer(); // Used to play sequences
        sequencer.open(); // Turn it on.

        // Get a Synthesizer for the Sequencer to send notes to
        Synthesizer synth = MidiSystem.getSynthesizer();
        synth.open(); // acquire whatever resources it needs

        // The Sequencer obtained above may be connected to a Synthesizer
        // by default, or it may not. Therefore, we explicitly connect it.
        Transmitter transmitter = sequencer.getTransmitter();

            if (value != audioPosition)
                skip(value);
        }

    // This timer calls the tick() method 10 times a second to keep
    // our slider in sync with the music.

    // And add them to this component.
