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.
I always strive to create unique sounds, mostly using layering and manipulating extraordinary samples to design completely new sounds. For example the basses in the drops are created with percussion loops and layered with bass one shots.
