With absolutely zero knowledge about any programs regarding music making I first used MuseScore to create a MIDI of the ARK: Survival Evolved Extinction theme. Let me tell you, with just a very basic understanding of music (I can read sheet music if you give me enough time) I went through a literal hell of trial and error, trying to recreate the song just by listening. After that, I imported the MIDI into FL Studio and changed the instrument (an organ sounded a bit weird lol and I also wanted to use something more "experimental"). Well yeah, tweaked some tiny things (as far as my non-existant knowledge goes) and that's what I have.
