Examples of javax.sound.midi.MidiChannel.noteOn()

javax.sound.midi.MidiChannel.noteOn()
Starts the specified note sounding. The key-down velocity usually controls the note's volume and/or brightness. If velocity is zero, this method instead acts like {@link #noteOff(int)}, terminating the note. @param noteNumber the MIDI note number, from 0 to 127 (60 = Middle C) @param velocity the speed with which the key was depressed @see #noteOff(int,int)

        // 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);
        }
        
        // Now send single midi on, and midi off message
        ch1.noteOn(64, 64);
