[sharing] Digital Waveguide Mesh

.quasar's icon

Played around recently with Digital Waveguide Meshes in gen~ to model membranes. Used this thesis as a basis.

There are a few examples in max for rectilinear Waveguide Mesh patches but from what I read so far, the "triangular" meshes offer some advantages in terms of dispersion.

This is a 3 nodes triangular Digital Waveguide Mesh examples (each node consist of 6 waveguides). Implemented a few other options like damping and nonlinearity.

Tell me if you're missing any abstraction of gendsp file but i think everything is in there !

Hi .QUASAR,

great patch, thanks!

Just a small suggestion to replace the third party object dcblock~ with a simple gen~ abstraction (native dcblock) or with [biquad~ 1. -1. 0. -0.9997 0] to prevent errors in the absence of the object (my case…).

Cheers

Thanks ! Did not spot that one, usually I actually use the native gen~ version ;)

The msp dcblock~ external comes from the Percolate package. great one btw => there's is actually a rectilinear waveguide mesh external in it (mesh2d~)

I totally missed this when it was first posted. This is fantastic!

Sounds very nice indeed, but always blows up on me. On Max 7 if it matters - anyone else have the same experience?
