SPEC: get/set Mono and Omni do not work

Name: vtR10009 Date: 07/23/2002


  The MidiChannel methods to get/set Mono and Omni
state do not function at all. They are not implemented for
default synthesizer.

This bug causes failure of new JCK tests:
 api/javax_sound/midi/MidiChannel/index.html#Mono
 api/javax_sound/midi/MidiChannel/index.html#MuteOmni
 
To reproduce the bug run the following test with JDK build 1.4.1-rc-b17:
------------------------------- test.java --------------------------------
import javax.sound.midi.*;
import javax.sound.sampled.*;

public class test{

    static boolean isSoundAccessDenied = false;

        try {

            synth.open();
            mChanArr = synth.getChannels();
            while ((i < mChanArr.length) && (chan == null)) {
                chanNum = i;
                chan = mChanArr[i++];
            }
            if (chan == null) {
                System.err.println("No channels in this synthesizer!");

                failed = true;
                System.err.println("the channel does not respond to messages "
                        + "sent on other!");
            }
            
        } catch (MidiUnavailableException mue) {
            System.err.println("MidiUnavailableException was thrown: " + mue);
            System.err.println("could not test.");
        } catch(InvalidMidiDataException invMDEx) {
            invMDEx.printStackTrace();
