In 1989, some of the limitations of the Ultimate Soundtracker were improved upon by two Swedish programmers, Pex “Mahoney” Tufvesson and Anders “Kaktus” Berkeman, which released a version known as NoiseTracker, which allowed for thirty-two instruments and was more open in terms of channel usage. Later versions of the program used the MOD file format, which stored both instrument samples and the tracks in the same file.

Common file extensions: MOD

Played in BZR Player using: libxmp
