Arp patterns or sequencing?

If we're talking about the same synth hook (to hear from 2:34 in the video), then I think it's hard to do because it's made with two different synth sounds. Aside from that, check through the 60 factory patterns or create a user pattern to get the rythm, then you should be able to play the notes with that rhythmic pattern. As for programming the whole sequence as one user pattern including note changes, I think it's too long.
