I saw Tangerine Dream doing this in the Apollo 25 years ago. Of course they needed an entire stage full of hardware to do what he's doing with a few teeny boxes. At the end of the day there is nothing new under the sun. Especially not in the field of music. However, give the guy a break, his tunes are very mellow. I could seriously have that sort of thing on in the background all day. I think he'd get better timing using a PC but... whatever.
