Episode: From Silicon to Darude Sand-storm: breaking famous synthesizer DSPs (39c3)
Description: Have you ever wondered how the chips and algorithms that made all those electronic music hits work? Us too!
At The Usual Suspects we create open source emulations of famous music hardware, synthesizers and effect units. After releasing some emulations of devices around the Motorola 563xx DSP chip, we made further steps into reverse engineering custom silicon chips to achieve what no one has done before: a real low-level emulation of the JP-8000. This famous synthesizer featured a special "SuperSaw" oscillator algorithm, which defined an entire generation of electronic and trance music. The main obstacle was emulating the 4 custom DSP...
