FWIW I just posted a rough draft program list for the DECO on PatchStorage. It is a work in progress but I think it’s a good start.

It only covers doubling, slap, and delay so far but I’ll add some flange and chorus when I can. Sum mode and Bounce mode are no problem. If there is a way to cover invert mode I certainly don’t know it. Right now I think there are three programs with 12 settings and, obviously, you can adjust to taste from there.
