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.
In this project i used Nexus, Serum and Sylenth1. This track is little strange, but sounds original. I think it's perfect to Selected and Hexagon records.
