Circular Banded Waveguide Help

Hi guys, I am attempting to model a wineglass using circular banded waveguides, as explained in this paper
http://imi.aau.dk/~sts/publications/dafx02bowl.pdf
in figure 12 there is a block diagram.

here is my patch attempting to the first three modes of a wineglass, the decay values havent been properly modeled yet.

I have managed to get what I think is right, but I have been trying to work these out for so long I’m not sure anymore. If someone could take a look for me it would be appreciated, as I’m not sure how to go forward.

Sounds damn good to me mate! Could you clarify the exact problem a bit more?

Waveguide synthesis isn’t really my bag sadly

The patch isnt that clean so its hard to see, but the outputs of the waveguides arent feeding back into the source like the diagram in the paper. When they are connected back up I get horrible feedback. It sounds right…so I guess its right?

So many combinations of waveguides has left me questioning myself

I certainly am having a little fun with feedback here – did a little edit:
