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.
Main bass comprises of 4 layers of Serum stacked together and heavily processed using EQ'ing, saturation, and compression to give it a punchy feel. Another Reese bass is used to bring the track together and glue all elements.
Synths are composed of 2 serum layers which are processed to give it transparency across the track. Plucks have been used to enhance the attack. A lot of other samples / stabs have been used to bring this banger together.
