In 1986, Huelsbeck released the SoundMonitor program for Commodore 64 computer. The program was released as a type-in listing in the German computer magazine 64'er. This program, featuring the idea of notation data rolling from down to up, is assumed[who?] to have a significant influence on Karsten Obarski's Ultimate Soundtracker (1987) which was a starting point for still continuing tradition of tracker music programs.
Huelsbeck has written soundtracks for more than 70 titles, the latest being Giana Sisters: Twisted Dreams. Many of his scores for the Commodore 64 are regarded as classics among enthusiasts today, most notably The Great Giana Sisters. He is best known for the soundtracks to the Turrican series of games. Chris's initial recognition arrived at age 17 when his composition "Shades" won first place in a music competition for the German 64'er magazine.
He also created a music replay routine for the Amiga called TFMX — "The Final Musicsystem eXtended", which features more musically-oriented features than rival Soundtracker, such as logarithmic pitch-bends, sound macros and individual tempos for each track.
