/**
 * Test update() on TunedSynthNoteInstrument (the highest JSyn Instrument in the class tree to
 * implement update(). Enter pitch, amplitude, hold values and click play() Then change amplitude
 * value while it is sustaining and click update(). The amplitude should change. While sustaining,
 * change both the pitch and the amplitude and click update(). no change, since it has not found a
 * SynthNote to update() - it looks up SynthNotes by matching pitch (or more generally, the
 * updateDimension).
