/*! \class Moog
    \brief STK moog-like swept filter sampling synthesis class.

    This instrument uses one attack wave, one
    looped wave, and an ADSR envelope (inherited
    from the Sampler class) and adds two sweepable
    formant (FormSwep) filters.

    Control Change Numbers: 
       - Filter Q = 2
       - Filter Sweep Rate = 4
       - Vibrato Frequency = 11
       - Vibrato Gain = 1
       - Gain = 128
