its the little “ditty” in the background that is made up of little lazer like stabs throughout the first min or two of “Milky Way”. I slowed down the tempo and counted 32 notes each time the melody is sequenced. I know he uses Massive and Sylenth1. Is he using the stepper/performer combo from Massive twice in a row, or the arp from Sylenth twice in a row, because each only go 16 notes.
