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.
I made everything in this track and bounced the synths into audio to save CPU! You'll still find the original patches in the project. The only thing I didn't create are the chords in the breaks, but I chopped em so they aren't the same as the sample pack.
