This might not seem terribly important to the pros but it makes me happy!

Would love to hear it, but mat.freq2samples is not included.

I always do that! Ok fixed it.

Nice as always Matt – is waveguide the same as karplus strong? I always thought it was something more complex.

I was wondering about this… I *think* it’s a waveguide if it emulates the impulse travelling down and then back up the string.. The idea is that delays A B and C emulate the impulse traveling one way, and the D E and F emulate the impulse traveling the other.

I could be very wrong about that.. I was looking at figure 1 here:

Thanks for this – it works alright as a filtered delay line for audio inputs, too :) Cheap solution as well.

Been playing around with this today, and thought I should share it:

"no patcher poly.waveguide_string"

Duh!

Nice. Thanks… Haven’t really had the chance to get very deeply into gen~ yet, but these patches are a big help for when I (eventually) get the time…

Just a heads up though, that the naming of the poly subpatch and the gen~dsp patch need to be altered as they are inconsistent with what the main patch is looking for: (gen.patcher: could not find gen patcher waveguide_string, poly~: no patcher poly.waveguide_string).

great patch. here is a zipped version

i mean, here is a zipped version

nice. this is pretty neat.
also; don’t attempt to edit the sympathy feedback… trust me, my speakers are angry at me right now.


February 26, 2012 | 3:11 pm

Very… very.. cool.

Extremely wonderful patch but it accumulates feedback gain when you hit the same note a few times. Anyone has any idea how to solve this?
The problem derives from the gen~ waveguide_string patch…
