Participation in the HOFA XMAS MIX CONTEST (#remixcontest or #mixcomp) is free of charge. All you need is a DAW and fun mixing and remixing.
You are allowed to master, copy & paste and pitch or even remove individual elements. For the sake of fairness it’s not allowed to add new tracks or to change tempo, pitch or structure of the song. The jury is looking for harmonious sound characteristics with balanced levels that fits in the genre, a well-defined spatial depth and a natural overall sound.
