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