There are lots of pedals these days that are designed as performance instruments in their own right. Check out the Erica Synths Nightverb; it's all chonky knobs and it doesn't even have stomp switches. You'd never put it on your floor.

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.
