+/*! \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
+    Drummer.h.
+
+    by Perry R. Cook and Gary P. Scavone, 1995 - 2002.
