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 the midi melodies here are original made by me, the bass in the the drop has three layers, the sound design of the pluck was made by me in serum and the vocal chop in the drop is from a sample pack.
