/** 	
	InsToot09.java

	Fill a MusicShape with frequency and amplitude data, perform it with a JMSL Instrument
	that bangs a JSyn circuit.
	This example is very strict about making no references to JSyn at all.
	it instantiates a new SineInstrument, gets it MusicDevice, opens an editor to test the MusicDevice,
	opens the MusicDevice, and proceeds.  Applet.stop() calls JMSL.closeMusicDevices();
