It just doesn't seem possible?

So I just stumbled onto a video (link bellow) of MISTABISHI playing dubs he made on a KORG EMX and I’m completely blow away. It just doesn’t seem possible to make what he is making with a EMX. As far as I know it’s not really a sampler.

I don’t know much about him so I thought I would ask here.
Is there some kind of element I missing here? Is he using other equipment with it? is the EMX really that good or is he just… that good?

TBH I’m a little jealous because I can’t make music like that in a DAW.
