Storm Summoner takes a pedal with lots of parameters [that would normally be set-and-go] and gives it that missing live performance UX. Singers in particular could use the sensors to modulate their voices.
What excites me is the flag-based system described in the review video at 11:45. You can set up stuff to happen (launch an LFO?) in response to other things that happen, like a value crossing a threshold. That takes it out of the realm of a dumb controller, and we already have enough dumb controllers.
Some pedals have a bunch of knobs which are a pain to adjust during live performance between the songs. So some pedals support changing the settings using MIDI interface. This device has builtin library of control codes fur such pedals. That way you can program presets for your MIDI controlled pedals in the storm summoner and during live performance quickly switch between presets with a click of single button as opposed to remember which of the half dozen pedals need to be stomped on/off for each song or worse adjusting the knobs.
All without a DAW too I'm guessing? I use an FCB-1010 for a lot of things but yeah it's obviously pretty useless without a DAW.
