Looks like someone was at yesterday’s show at the 104 in Paris! If you want to know, it was wonderful 
To add on Four Tet’s setup you can see the core of it in this video:
Seems like he swapped the Pioneer mixer for a Model 1.
Regarding the modular, apparently it was assembled with the help of Taraval (great techno artist who is also part of Caribou’s live band) you can see it on this IG post: https://www.instagram.com/p/Bh1ZKGdl1Pn/
When you listen to his live recordings, you can hear he mostly uses it as a drum machine to add rhythmical parts to his transitions. You can also hear him retune his telharmonic a few times during his sets, which could be weird, but in my view adds a cool organic aspect. It seems to be sequenced by korg ER-1, or maybe both are played in combination.
If you want to see more, I recreated his setup in modular grid here: https://www.modulargrid.net/e/racks/view/932699
Yeah, I’m kind of obsessed…
