Hi
I've been using a patch for a digital waveguide I found to try and build my own

I've just realized that the delay lines he made are bi-directional, so they include both the left and right traveling waves. In the patch I have connected both delay lines up via a scattering junction, as this is the only way I can select input and output position.

Basically I want to be able to select the output out of the same delay line that I am able to select the input, as I only want to model 1 string, not the sympathetic resonance and output of one string which is excited by another.

I have included bits of description in the patch, basically the left hand side is the waveguide I can select input position for, but I also want to select the output position for the same one, therefore not needing the scattering junction or a second waveguide

Any help would be greatly appreciated

(ps i haven't sorted out the loadbangs properly yet, so values for top and bottom filters, waveguide lengths and filter values need to be put in before it will make any sound, sorry)

Thank you

I thought maybe cutting all the parts from the output delay line that don't actually create a delay line then connecting them up to the input delay line, but this doesn't work.
Does anybody have any suggestions?
thanks
