Hello.

I am using JDK 1.3.1 on FreeBSD with appropriate patches added. I get an

empty array from the getInstruments() method of the Soundbank interface.

Maybe this is a FreeBSD specific bug, I don't know. In any case, it
would be nice to hear if anyone else has the same problem. Below is a
short example.

Best Regards,
Mats Peterson

import javax.sound.midi.*;
import java.io.*;

public class SbTest {
    public static void main(String args[]) {
        Synthesizer synthesizer = null;
        Soundbank sb;
        Instrument instruments[];

        try {
            if ((synthesizer = MidiSystem.getSynthesizer()) == null) {
                System.out.println("getSynthesizer() failed!");
                System.exit(1);
            }
            synthesizer.open();
        } catch (Exception ex) {
            ex.printStackTrace();
            System.exit(1);
        }

        if ((sb = synthesizer.getDefaultSoundbank()) == null) {
            System.out.println("Couldn't get default sound bank");
            System.exit(1);
        }

/* The following returns an empty array with JDK 1.3.1 in FreeBSD */

       instruments = sb.getInstruments();
        if (instruments.length == 0) {
            System.out.println("Empty instruments[] array");
            System.exit(1);
        }

        System.exit(0);
    }
}
