Digitalism - Blitz

I’d like to know, is the melody in this programmed or is it an arp? Best example is from 1.45 onwards. If it’s an arp, how is the alternating pattern acheived? Thanks.



Digitalism is great, +1

Yeah this is a great song…to me it sounds like an arp that is being triggered by a bunch of diferent chords in a progression.
