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.
Punch and progressive drums, modern bassline, great reese bass, guitar loops to improve the ambience, brasses and plucks, original lead melody, royalty-free vocals and a lot of effects in the background.
