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 melodic and drum elements (except pad & texture loop) are made by me. I've used vocal from royalty free sample pack.
Sample pack Dark Melodic Techno
