    --------------------------------------------------------
    A JMSL file which is an intermediary between a circuit and
    a MusicJob. This instrument controls an FM pair which feed 
    into a StateVariableFilter.  The cutoff frequency of the 
    filter is varied as a function of the two oscillator 
    frequencies.
	   
    The highPass and lowPass outputs are then fed to left and
    right channels respectively.
