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
The subs are not layered because it is not justified. The piano is layered. There is one with a higher and one with a deeper tone. Also, the piano arp is 2 octaves higher to have a ring and draw attention.
