All the instruments, melodies and arrangements have been 100% made by the producer. No free-royalty use loops have been used to create any part of the instrumental of this track. There can only be loops only in the drums section (claps, shakers, top loops, etc) and ambient or vocal samples as a support of the production arrangement.
Process note
Probably the arrangement on this track takes role much on the track and for the bass, leads and other things in the drop are controlled by automation mostly.
