Java SE (Java Platform, Standard Edition)

Hi,

I have a midi file which is recorded with Yamaha PSR-A3000 ( external midi synth) I have saved it on my computer and would like to play it back from my computer.  I wrote the Jave code below, It shows PSR MIDI device and the input port is the 4th one. however, I cannot get MIDI file played on my Yamaha PSR

import javax.sound.midi.MidiSystem;
import javax.sound.midi.Sequence;
import javax.sound.midi.Sequencer;
import java.io.File;
import javax.sound.midi.MidiDevice;
import javax.sound.midi.MidiUnavailableException;
import javax.sound.midi.Receiver;
import uk.co.xfactorylibrarians.coremidi4j.CoreMidiDeviceProvider;

public class psrMidiPlayer {

   /**
  * Play a Midi file.
  */
   public static void playMidiFile(String fileName, int DEVICE_NUMBER) {
   try {
   for (Receiver receiver : MidiSystem.getSequencer().getReceivers()) {
  receiver.close();
   }
   System.out.println("Working MIDI Devices:");
   for (javax.sound.midi.MidiDevice.Info device : CoreMidiDeviceProvider.getMidiDeviceInfo()) {
   System.out.println(" " + device +" "+ device.getVendor());
   }

   MidiDevice.Info[] MidiDeviceInfos = MidiSystem.getMidiDeviceInfo();
   //find the suitable device number here, based on some criteria
   MidiDevice MidiOutDevice = MidiSystem.getMidiDevice(MidiDeviceInfos[DEVICE_NUMBER]);


   if (!(MidiOutDevice.isOpen())) {
   try {
   MidiOutDevice.open();
   } catch (MidiUnavailableException e) {
  e.printStackTrace();
   }
   }

   Receiver MidiOutReceiver = MidiOutDevice.getReceiver();
   Sequencer MidiOutSequencer = MidiSystem.getSequencer();


   System.out.println( "getMaxReceivers() =" + MidiOutDevice.getMaxReceivers());
   System.out.println( "getMaxTransmitters() =" + MidiOutSequencer.getMaxTransmitters());

   //Add the new MIDI out device here.
   File myMidiFile = new File(fileName);
   MidiOutSequencer.getTransmitter().setReceiver(MidiOutReceiver);

   MidiOutSequencer.open();
   Sequence mySeq = MidiSystem.getSequence(myMidiFile);
   MidiOutSequencer.setSequence(mySeq);

   MidiOutSequencer.start();
   //MidiOutSequencer.close();
   } catch (Exception ex) {
  ex.printStackTrace();
   }
   }

   public static void main(String args[]) {
   int i = 3;
  playMidiFile("/pass2midifile/bahar-martik.mid", i);
   }
}

The external Synth is using standard Yamaha USB-MIDI driver and all I hear it playing is a single note E3 on piano and when I monitor the incoming midi messages they are all on channel one and E3.
