Matt Gray is a British composer who has composed music and sound for numerous games at Codemasters and System 3. Some of his prominent works include Last Ninja 2 and Driller.
Initially, Gray used Soundmonitor and the Ariston driver, sometimes optimized by game programmers and at that sometimes with declined quality. Soon after, the founders of Codemasters convinced him to write his own driver. Following that, he jammed on a Casio MT-45 and typed the data in assembly.
According to Gray, he had to compose the music in 6502 assembly. He used a sound driver by Gavin Raeburn. In most of the games he works on, he is often uncredited or listed as "Matt Grey".
