Do you mean the tone or the style? If you mean the tone, it sounds like a pretty basic 'sine wave' without much (or any) modulation. Very simple and clean. Almost any synth can pull that off.

If you're talking about the style of playing, it's just an arpeggiated chord/scale.
Basically, you take a chord or scale and just play the notes back individually in sequence rather than at one time.

Hope that helps!
