How do you implement multiple tempos using one sequencer in java

I've been working on metronome music app in Java and I stumbled on a complication. Consider the code below which was taken from: http://ift.tt/1zLCE40. The implementation here is similar to what I have done to get multiple tempos. The only problem I have with this is that it makes things a little messy, I was hoping maybe somebody may offer an alternative way to having multiple tempos preferably by using one sequencer.

import java.util.*;
import javax.swing.*;
import javax.sound.midi.*; 

public class MetronomeTestApplet extends JApplet
{
     public void init()
     {
          MetronomeTest metTest = new MetronomeTest();
          metTest.play();
     }
}

class MetronomeTest
{
     Sequencer sequencer1=null;
     Sequencer sequencer2=null;

     Sequence sequence1=null;
     Sequence sequence2=null;

     Track track1=null;
     Track track2=null;

     MidiEvent newEvent=null;

     int volume = 90;     
     int tempo     = 100;

     public MetronomeTest()
     {     
          try
          {     // SEQUENCER 1
               sequencer1 = MidiSystem.getSequencer();
               sequencer1.open();
               sequence1 = new Sequence(Sequence.PPQ, 16);
               track1 = sequence1.createTrack();

               ShortMessage instrumentMsg = new ShortMessage();
               instrumentMsg.setMessage(ShortMessage.PROGRAM_CHANGE, 0, 115, 0);          // 115 == woodblock
               track1.add(new MidiEvent(instrumentMsg, 0));

               // SEQUENCER 2
               sequencer2 = MidiSystem.getSequencer();
               sequencer2.open();
               sequence2 = new Sequence(Sequence.PPQ, 16);
               track2 = sequence2.createTrack();

               instrumentMsg = new ShortMessage();
               instrumentMsg.setMessage(ShortMessage.PROGRAM_CHANGE, 0, 117, 0);          // 117 == melodic tom
               track2.add(new MidiEvent(instrumentMsg, 0));
          }
          catch (Exception e) { e.printStackTrace(); }
     }

     public void destroy()
     {
          sequencer1.stop();
          sequencer1.close();

          sequencer2.stop();
          sequencer2.close();
     }

     public void play()
     {
          try
          {               
               // LOAD SEQUENCE 1               
               for (int i=0; i<4; i++)
               {
                    ShortMessage noteOnMsg = new ShortMessage();
                    noteOnMsg.setMessage(ShortMessage.NOTE_ON, 0, 60, volume);
                    track1.add(new MidiEvent(noteOnMsg, 0 + 16*i));

                    ShortMessage noteOffMsg = new ShortMessage();
                    noteOffMsg.setMessage(ShortMessage.NOTE_OFF, 0, 60, volume);
                    track1.add(new MidiEvent(noteOffMsg, 16 + 16*i));
               }

               // LOAD SEQUENCE 2               
               for (int i=0; i<8; i++)
               {
                    ShortMessage noteOnMsg = new ShortMessage();
                    noteOnMsg.setMessage(ShortMessage.NOTE_ON, 0, 60, volume);
                    track2.add(new MidiEvent(noteOnMsg, 0 + 8*i));

                    ShortMessage noteOffMsg = new ShortMessage();
                    noteOffMsg.setMessage(ShortMessage.NOTE_OFF, 0, 60, volume);
                    track2.add(new MidiEvent(noteOffMsg, 8 + 8*i));
               }

               // LOAD AND START SEQUENCERS
               sequencer1.setSequence(sequence1);
               sequencer1.setTempoInBPM(tempo);
               sequencer1.setLoopCount(Sequencer.LOOP_CONTINUOUSLY);

               sequencer2.setSequence(sequence2);
               sequencer2.setTempoInBPM(tempo);
               sequencer2.setLoopCount(Sequencer.LOOP_CONTINUOUSLY);

               sequencer1.start();
               sequencer2.start();
          }
          catch (Exception e) { e.printStackTrace(); }
