Mark Knight, also known as "TDK" (or The Dark Knight) is a well-known Amiga chiptune/demoscene musician, and video game composer/sound designer. It was on his 11th birthday that Mark was given a Commodore 64 computer and he quickly took a liking to the music which was being produced by the machine. Although he wrote music using the Electrosound software it wasn't until Mark bought a 2nd hand Commodore Amiga A500 in 1989, and was introduced to the Soundtracker music software that he started to compose music more seriously. Eventually he found that he enjoyed writing 'chiptunes' on the Amiga using a technique pioneered by 4-Mat. As a member of Melon Dezign and Anthrox, his chip music sounds often appeared in Crystal and Anthrox cracktro's. As a game musician, he converted several existing game tunes to the Amiga, and also made a number of original compositions for many formats from the Nintendo Entertainment System through to the PlayStation and PC. After leaving the Amiga demo scene in 1993, he has worked for the computer game developers - Mindscape Group, 3D Realms, Bullfrog Productions, Electronic Arts, Climax Group, Visual Science and is currently working for Codemasters. His notable music compositions are used in titles such as Dungeon Keeper 2, Populous: The Beginning, Warhammer: Dark Omen, Wing Commander amiga version, Duke Nukem 3D Total Meltdown, and he has since had sound design credits in games such as the Develop Magazine Audio Accomplishment nominated Race Driver: GRID, Develop Magazine Best art and sound nominated Sudeki, Shox, Formula One, and Theme Park World - which won a BAFTA Interactive Entertainment Awards award in 2000 for 'best sound in a video game'. In 2011 TDK came out of retirement to release two new chiptunes under the name "Mark 'TDK' Knight. He is currently working on a Chiptune Album, and chip music for an un-announced game title.
