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 started out with the bass on the drop, made with xfer serum, and the vocals that took the song. Pretty straight forward using Ableton Native Plugins, X-Fer Serum and Spire.
