/*! \class Drummer
    \brief STK drum sample player class.

    This class implements a drum sampling
    synthesizer using WvIn objects and one-pole
    filters.  The drum rawwave files are sampled
    at 22050 Hz, but will be appropriately
    interpolated for other sample rates.  You can
    specify the maximum polyphony (maximum number
    of simultaneous voices) via a #define in the
