|
STK flute physical model class.
|
|
<p>
|
|
This class implements a simple flute physical model, as discussed by Karjalainen, Smith, Waryznyk, etc. The jet model uses a polynomial, a la Cook.<p>
|
|
This is a digital waveguide model, making its use possibly subject to patents held by Stanford University, Yamaha, and others.<p>
|
|
Control Change Numbers:<ul>
|
|
<li>Jet <a class="el" href="classDelay.html">Delay</a> = 2</li><li><a class="el" href="classNoise.html">Noise</a> Gain = 4</li><li>Vibrato Frequency = 11</li><li>Vibrato Gain = 1</li><li>Breath Pressure = 128</li></ul>
