Examples of programChange()

javax.sound.midi.MidiChannel.programChange()

Changes a program (patch). This selects a specific instrument from the currently selected bank of instruments.

The MIDI specification does not dictate whether notes that are already sounding should switch to the new instrument (timbre) or continue with their original timbre until terminated by a note-off.

The program number is zero-based (expressed from 0 to 127). Note that MIDI hardware displays and literature about MIDI typically use the range 1 to 128 instead. It is possible that the underlying synthesizer does not support a specific program. In order to verify that a call to programChange was successful, use getProgram. @param program the program number to switch to (0 to 127) @see #programChange(int,int) @see #getProgram()

        AudioInputStream stream = synth.openStream(format, null);
                        
        // Make all voices busy, e.g. 
        // send midi on and midi off on all available voices        
        MidiChannel ch1 = synth.getChannels()[0];
        ch1.programChange(48); // Use contionus instrument like string ensemble
        for (int i = 0; i < synth.getMaxPolyphony(); i++) {            
            ch1.noteOn(64, 64);
            ch1.noteOff(64);
        }

        synth.unloadAllInstruments(synth.getDefaultSoundbank());
        synth.loadAllInstruments(sf2);
        
        // Send out one midi on message
        MidiChannel ch1 = synth.getChannels()[0];
        ch1.programChange(0); 
        ch1.noteOn(64, 64);
        
        // Read 1 sec from stream
        stream.skip(format.getFrameSize() * ((int)(format.getFrameRate() * 2)));
