Reply to Controllers in live performance - a question...

I'm trying to get my head around how extensively controllers are being used as PRIMARY control devices in live performances. I'm not worried about what software is used, but what I'm looking for are people who interact with that software with controllers and not more traditional means. So to be clear, if they use CDJs or turntables I'm not at all interested in them - even if they use controllers in a cool way (Shiftee is a great example of this - amazing routines but primary "controller" is a turntable).

So who do you guys know of?
