FM0 only makes sense to me as a pedalboard amp. An add-on to pedalboards with a power amp on or off the board. As such it doesn't need switches, but it does need a screen and controls (buttons, knobs), of course. This product would allow legions of traditional "amp+pedalboard+MIDI" users to add Fractal Audio modeling to their rigs, controlling it through the MIDI controller [edit: or FC] they already own.
