What drum machine/sampler is Beck using here?

[tradinghair]

Here's a video of Beck playing Loser live with a guitar and drum machine/sampler/looper. He uses it for a drum loop, to layer vocals, and then to mess with the sounds, all live. Starts messing with it at the 4 minute mark. Anyone know what it is?
