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.
Chillout lounge record for beaches and dreams.
I always try to keep my projects well organised in case you will need to change some stuff.
Thanks for the support!
