Thomann had (still have?) this thing called "stompenberg", where they put up some mechanical switching system so that you could play audio files through the actual pedals in the system, and turn on the knobs / parameters.
In the recent years some smaller businesses have started to offer outboard gear in this way. You upload some stem, and can process it through their hardware remotely, and get back the results.
No way! My friend and I were half joking about building that as a sequel to realtuner. If nothing else, it'd be a great excuse to buy more gear.
