Detailed Description

Two-dimensional rectilinear waveguide mesh class.

This class implements a rectilinear, two-dimensional digital waveguide mesh structure. For details, see Van Duyne and Smith, "Physical Modeling with the 2-D Digital Waveguide Mesh", Proceedings of the 1993 International Computer Music Conference.

This is a digital waveguide model, making its use possibly subject to patents held by Stanford University, Yamaha, and others.

Control Change Numbers:

• X Dimension = 2
• Y Dimension = 4
• Mesh Decay = 11
• X-Y Input Position = 1

by Julius Smith, 2000 - 2002. Revised by Gary Scavone for STK, 2002.
