How I Did It

Uses samples from:
Tools I Used
Jeskola Buzz freeware.
See :

Samples I Used
No real sample but a brass soundfont. Soundfonts let you write your own melodies, just like having the real instrument :)
Original Samples
All here is written and all sounds created by me (various synths, drums, Fx, mastering...).
Process
Buzz is like a complete studio. You can create sounds, arrange, write melodies, master, eq and so on...
Other Notes
I had a lot of fun making it! I just splitted the vocal at some point. I have used some Fx to make the vocal "ducked" in some place.
