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.
Summer chill house record! I try to pick my vocals so that labels don't decline your track because of overused vocals. I always keep my projects very organised so it will be easy for you to change thins up if needed.
