Question about remixes

Hey! I was just browsing through trapstep’s youtube page yesterday and saw a trap remix to Under Control by Calvin & Alesso.

I was wondering, does the artist (Bare) create the trap drop by re-creating the melody? Or did he just simply speed up or slow down the original drop?
