    createButton: function(filter, onDown, onUp){
      return Button({
        port: duplexPort, 
        grabber: grabber
      }, filter, onDown, onUp)
    },
    createNoteMatrix: function(mapping, color){
      return NoteMatrix({
        port: duplexPort,
        grabber: grabber
      }, mapping, color)
