Hello everyone,
I have got the follg code which when compiled gives the error
"Expected Instrument[] but founf javax.sound.midi.Instrument[]"
at the line
Instrument instrs[] = synth.getLoadedInstruments();

Can anyone please help me in this regard?
import javax.sound.midi.*;
public class Waves
{
public static void main(String[] args)
{
try
{
// Locate the default synthesizer
Synthesizer synth = MidiSystem.getSynthesizer();
// Open the synthesizer
synth.open();
// Get the available Midi channels - there are usually 16
MidiChannel channels[] = synth.getChannels();
// Get the synth's soundbank where all the sounds are stored
Soundbank bank = synth.getDefaultSoundbank();
// Load all the available instruments
synth.loadAllInstruments(bank);
// Get a list of the available instruments
Instrument instrs[] = synth.getLoadedInstruments();
Instrument seashore = null;
// Loop through the instruments
for (int i=0; i < instrs.length; i++)
{
// Stop when you find the seashore
if (instrs[i].getName().equals("Seashore"))
{
seashore = instrs[i];
break;
}
}
if (seashore == null)
{
System.out.println("Can't find the beach");
System.exit(0);
}
// Get the information describing the Seashore instrument - the
// patch contains the soundbank and program number
Patch seashorePatch = seashore.getPatch();
// Set 5 channels to use the Seashore instrument
channels[1].programChange(seashorePatch.getBank(),
seashorePatch.getProgram());
channels[2].programChange(seashorePatch.getBank(),
seashorePatch.getProgram());
channels[3].programChange(seashorePatch.getBank(),
seashorePatch.getProgram());
// Start the Seashore note on 3 different channels. By waiting a short
// time before starting the next note, you get a much more continuous sound
channels[1].noteOn(32, 127);
Thread.sleep(3500);
channels[2].noteOn(32, 127);
Thread.sleep(1500);
channels[3].noteOn(32, 127);
// Wait forever
for (;
{
try { Thread.sleep(999999999); } catch (Exception ignore) {}
}
}
catch (Exception exc)
{
exc.printStackTrace();
}
}
}

Thanks in advance
Indira.
