I've seen a few posts regarding Eurorack as a guitar processing rig. Has anyone successfully pulled this off in a live set-up? I ask because modular is a very hands-on format requiring at least one hand and guitar almost always requires two. How do you go about tweaking a Clouds module in the middle of a song?

I can see using modular for post processing especially if you're reamping the signal through modular. But I'm most curious about the ergonomics of actual use rather than being able to theoretically put it into practice. I'm not a guitarist by trade and it's for my own edification.
