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
Drop bass is made of 2 layers of Serum, one Serum sub bass, a Serum lead, and other pads/FX/drums.
