More questions about the Warehouse - Lighting Rigs

Back with more questions around last weekend in the Warehouse, or really just the production of events like this. How are the lights/visuals/lasers being operated? Bicep clearly had a whole prepanned show to go with it, and Four Tet’s visuals looked pretty damn slick and went along with the flow nicely. But others like when I saw BN/VTSS, Sammy, Honey Dijon, Landry it all seemed a little more muted. Do specific DJs have their own specific lighting person running the show? Or is it a shared person(s) for the weekend operating it across multiple sets?

What sort of music-to-lighting software are they running? A decade ago I attended a talk from the creator of TouchDesigner. It was pretty interesting stuff.
