The 2D Waveguide Mesh computes realistic-sounding simulations of struck plates. An initial version of the synthesis technique in the early 90's provided a baseline technology which has been ported to numerous computer music languages and platforms but hasn't yet found the greater musical use that its interesting sonic qualities suggest are possible. Enhancements to the technique are described which include deriving wavefield output from the mesh at multiple nodes and injecting efficient non-linearities at mesh edges. An updated formulation of the original C++ code provides the computational framework. The overall project goal is a synthesis instrument of interest for real-time music performance and studio composition. The present report is accompanied by an open source implementation incorporating the enhancements described.
