JMSL Tutorial: Instruments and Interpreters

Here, we've declared a subclass of Instrument called PrintingInstrument, which overrides play() as described in the previous tutorial. We've also built a four dimensional MusicShape and plugged one of these PrintingInstruments into the MusicShape's Instrument. Here's how:

        
        myMusicShape.setInstrument(new PrintingInstrument());

The results are shown in the applet below. Note that the duration of each is the first element in the array.
