/***************************************************/
/*! \class Clarinet
\brief STK clarinet physical model class.
This class implements a simple clarinet
physical model, as discussed by Smith (1986),
McIntyre, Schumacher, Woodhouse (1983), and
others.
This is a digital waveguide model, making its
use possibly subject to patents held by Stanford
University, Yamaha, and others.
Control Change Numbers:
- Reed Stiffness = 2
- Noise Gain = 4
- Vibrato Frequency = 11
- Vibrato Gain = 1
- Breath Pressure = 128
by Perry R. Cook and Gary P. Scavone, 1995 - 2005.
