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. It is the standard in which most of producers work, in a project you will find MIDI files made by the producer, but also melodic loops.
the guitar was used in two places, the break (used completely) and the drop in the form of chops. The bassline was composed of 3 serum layers, a sub layer, a deep house style mid bass, and a lead to make the sound more full and different.
