The base is original from the producer (chords and melodies), but is complemented with elements that complement the song that come from samplepacks, usually, vocal chops, guitars, wobbles sections, glitch effects.

The lead and the main bass was made with Serum.
The vocal chops and the chords of the break make the summer atmosphere.
