This is the standard that most of producers work on. In these type of projects the base is original from the producer — chords, melodies, leads, etc — but it contains additional melodic elements that complement the track and come from royalty-free sample packs. They are usually vocal chops, real instrument chords or textures, wobbles basses, glitch effects, etc. In a project file of this category you will find MIDI files created by the producer, but also melodic loops
Process note
I started with the chords in Analog Lab VST, using violin and strings stems from a Cymatics loop, along with a vocal loop also from Cymatics. The drums were created from scratch. VSTs used include Analog Lab and Reaktor 6. The key is B minor, with a tempo of 143 BPM.
