Hey all, I've written a pretty kick-ass patch but I'm having some problems with a feedback loop.. this is the workflow:

- uses n and m for a chladni pattern in a circular membrane

I'm using a sand algorithm from another patch that simulates the movement of sand on the plate, however, its too slow and I cant work out why...

A bang starts the patch in the left inlet and on the right the pattern is passed as a matrix!.

I cant upload the full patch because there are too many java files, but once I've finished it I'll get it on my website.

- person speaks
- analyzes frequency
- produces n and m 
- uses n and m for a chladni pattern in a circular membrane
- produces pattern

You could try jit.gl.slab with @file op.add.jxs and also @file op.mult.jxs instead of jit.op + and * objects, to speed up your process ... ?

eheh yeah, I thought that too but it doesn't have an impact! Any other ideas guys?

jit.xfade will be a lot quicker that your homebuilt p mixer.

i even use it instead of [jit.op *] for scaling sometimes when i'm 

really chasing fps. (see attached and zipped benchmark patches)
