Constructing a MIDI Sequence...tickCounts

[Udit Manektala]

So im trying to dynamically construct a MIDI Sequence and i cant seem to get the ticks and timings figured out. So according to the following code, I should have one note play (Note 64). Then Stop and then another Note play (Note 67) and stop.

What ends up happening is that one note plays (64) and then the next note plays for an instant and it stops. What am I doing wrong. I admit my tick concepts arent the clearest right now but im working on them.

Sequencer sequencer=null; 
 Synthesizer synthesizer=null;
try
{
        Sequence mySeq=new Sequence(Sequence.PPQ,10 );
        ShortMessage sm= new ShortMessage();
        sm.setMessage(ShortMessage.NOTE_ON, 0, 64, 99);
        MidiEvent me = new MidiEvent(sm,32);
        me.setTick(10);
        
        ShortMessage sm2= new ShortMessage();
        sm2.setMessage(ShortMessage.NOTE_OFF, 0, 64, 99);
        MidiEvent me2 = new MidiEvent(sm2,32);
        me2.setTick(20);
        
        ShortMessage sm3= new ShortMessage();
        sm3.setMessage(ShortMessage.NOTE_ON, 0, 69, 99);
        MidiEvent me3 = new MidiEvent(sm3,32);
        me3.setTick(30);
 
        ShortMessage sm4= new ShortMessage();
        sm4.setMessage(ShortMessage.NOTE_OFF, 0, 69, 99);
        MidiEvent me4 = new MidiEvent(sm4,32);
        me4.setTick(40);
 
        
        Track t = mySeq.createTrack();
        t.add(me);
        t.add(me2);
        t.add(me3);
        
        sequencer = MidiSystem.getSequencer( );
    
        sequencer.open( );  
        synthesizer = MidiSystem.getSynthesizer( );
        synthesizer.open( );
        System.out.println("R:"+mySeq.getResolution());
        sequencer.setSequence(mySeq);
        sequencer.start();
}
