39C3 — Recreating Sandstorm [Roland JP-8000 Patch].
“Sandstorm” is powered by the Roland Supersaw, and synth nerds have argued for a decade about how it’s made. The JP-8000 is a digital synthesizer, though, so it’s just code, run through custom DSP chips. If you could reverse engineer these chips, make a virtual machine, and send them the right program, you could get the sound 100% right. Think MAME but for synthesizers. That brings us to [giulioz]’s talk at the 39th Chaos Communication Congress, where he dives deep into the custom DSP chip at the heart of the JP-8000.

A #3c93 talk from @giulioz, about reverse-engineering the Roland #jp8000 synth, including figuring out its proprietary DSP architecture from scratch:

They've made a plugin that emulates a 100% accurate JP8K (just bring firmware), and uses a JIT compiler to make it run acceptably (the beast had 4 DSP chips in series, running at 2x the CD sample rate).

(I had a JP8K in the 90s and have fond memories of its sounds.)


This talk is a sequel to my last year's talk "Proprietary silicon ICs and dubious marketing claims? Let's fight those with a microscope!", where I showed how I reverse engineered a pretty old device (1986) by looking at microscope silicon pics alo...
