Andreas Jochen Hippel is a musician from Kirchheimbolanden in southwest Germany. He played one of the most prominent roles in computer music during the 16-bit microcomputer era, composing hundreds of tunes for games and demos. He was also an experienced Amiga programmer and ported many of Thalion Software's Atari ST titles. He no longer composes music for a living and in 2006 he was working in logistics. Jochen's first computer music was a set of Christmas songs that he arranged in a rock style on his school's Commodore 64. As a member of The Exceptions under the handle Mad Max, he wrote most of the music for their demos including the B.I.G. Demo. The demo was essentially a large collection of C64 tunes that was ported across to the Atari ST's Yamaha YM2149 sound chip using Jochen's own driver to get the most out of it. Jochen then had to fix all the music in order to get it to sound correct on the ST as the YM2149 has no resonance filter, no Oscillator sync, no combined waveforms, no ASDR enveloping and no ring modulation, and it has fewer waveforms than the MOS Technology 6581.
