That all sounds like fun ... maybe I can convince @lokki to give me the files too? Pretty please?The primary way it communicates is through NPRN. @lokki gave me files that listed the controls, and I created my own overkill editor in MD.
The problem is two-fold: (1) communication is not two way and (2) you can create these sounds, but I don't think you can save them to the pedal? At least, that's how I understand it.
