First vocable output from a waveguide membrane

Very early stuff but a rendering of the vocable word sebosebesusasobesebosebasusasobesebosebesusasobesobosebesusasobesebosebesusasobesebosebasusasobesebosebesusasobesobosebesusasobe is here.

The percussive beat you hear in the background is the excitation of the mesh, bursts of pink noise from the ‘b’s and white noise from the ‘s’s.  The vowels control the ‘tension’ of the mesh.

The waveguide mesh ugen mentioned in my previous post and used here is now in sc3-plugins.

Waveguide mesh unit generator

After quite a bit of fiddling, I got a waveguide mesh working. It’s a physical model of a drum head, basically lots of bidirectional, single sample delays connected in a triangular mesh to form a hexagon. [update: now a second extern is in there that tessellates a circle instead].

It sounds pretty good already, next plan is to play with different ways of exciting it.

The supercollider plugin, together with some haskell (hsc) code for testing it, is downloadable here.

[update: native sclang code and classes included now too]

[another update: new version with patch from Dan Stowell, it uses less CPU now]
