I'm currently (modestly) trying to implement a Gardner reverb in gen~. I found a detailed tutorial in The Csound Book and I thought I could try to replicate it in gen. I am a big fan of the Datorro reverb but I've been using it too often recently and I wanted a little change.

To be honest I don't think I will be able to implement the whole design any time soon but for the moment I'm trying to replicate two key ingredients of the Gardner Reverb : a nested allpass filter and a double nested allpass filter.

FYI this is a link for the Gardner Reverb designs in the Csound Book:

Did anyone ever use nested allpass in gen? I will post my attempt of a nested allpass in gen~ later today

nested-allpass-filter-implementation-in-gen

You'll find in the patch I attached my attempt at creating a nested-allpass filter as well as a double-nested allpass filter in gen. If anyone can tell me if I am on the right track that would be awesome! Otherwise, I'll persevere and hopefully one day I'll manage to replicate a nice FDN reverb in gen~

you should probably just look at the "gen~.gigaverb.maxpat" and "gen~.waveguide.maxpat" examples in your gen~ examples folder for examples of nested allpass fdn network implementations.
