Re: Opening instruments with appletviewer vs. browser

A Java program that I've written that makes sounds works fine when I
test it with appletviewer, but not when I use a browser (Firefox or
Explorer). The difference is that when I call the MidiSystem
synthesizer with getAvailableInstruments, I get a bunch of instruments
(411) when running it with appletviewer, but none when using a browser.
Why the difference? A short program that demonstrates my problem is
below.

Momo

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

public class SimpleSound extends JApplet
{
   public void init()
   {
      try {
         Synthesizer synth=MidiSystem.getSynthesizer();
         synth.open();
         Instrument[] instr=synth.getAvailableInstruments();
         JOptionPane.showMessageDialog(null,"instr.length="+instr.length);
      }
      catch (MidiUnavailableException e) {
      }
   }

}
