The Atari ST's most famous music composer. Broke through as "Mad Max" in the BIG Demo, where he rendered C64 classics on the Atari's soundchip. In the game business, he worked mainly for Thalion. Together with Chris Hülsbeck, he converted the 7-channel TFMX format to the ST and developed it further into his own COSO format. Jochen Hippel is now retired from the computer world since several years, though he sometimes makes short reappearances with new and old demo soundtracks.
