NoiseTracker is a freeware tracker created in 1989 for the Amiga platform.
[1][2] It was based on the Ultimate Soundtracker and developed by Pex "Mahoney" Tufvesson and Anders “Kaktus” Berkeman.
[3][4] It was used by Amiga game musicians to create music with four channels of sampled stereo sound.
Additionally it was used by some music groups as a low cost alternative to a full studio for rudimentary backtrack music production.
One of the users is Axwell of Swedish House Mafia.
