last night we got to be in the audience for an extremely well-presented and interesting talk here at 39C3 about how the DSP in the Roland JP-8000 (famous 90's digital synth, origin of the SuperSaw) was reverse-engineered. the video is now up, check it out! https://media.ccc.de/v/39c3-from-silicon-to-darude-sand-storm-breaking-famous-synthesizer-dsps
wait oh my god the DSP algorithm for a sawtooth wave is literally just for(t=0;;t++) { acc += pitch; saw[i] = acc; }
the integer overflow is what makes it cycle!
god we have to get into DSP huh
