I'm not sure I agree with that; I have a couple of pedals and MIDI devices which would benefit from a MIDI controller like this.
Maybe a HX Stomp, a C4, and a Minitaur, even a guitar synth.
I'm assuming that you can encompass the settings for several devices for each song (or sections thereof) in a set-list, maybe even shift the pedals off the floor and safely into a rack.
I meant in the role it fulfils, ie. a single pedal to control multiple MIDI devices at a time.
It's plain to see it is a step forward in at least presentation of the information.
