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.
All instruments, melodies and drums are original and 100% custom made by the producer. Only the vocal in this beat is a royalty free loop.
