/*! \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 - 2002.
