Poly-Synth is a 3-voice polyphonic synthesizer ASIC, taped out on Tiny Tapeout SKY26c. It takes an input as a tuning word over SPI, passes it through one of 3 DDS cores, which consist of a phase accumulator and a shaper. Finally, the 3 voices are mixed arithmetically and are output via oversampling with a 1st-order Sigma-Delta module.
