SD Synthesis Details

SD (Spectrum Dynamic) Synthesis was modeled on traditional DCO-VCF-DCA analog synthesis but used waveforms that included predefined variations over time. The SD sound source is a 4-bit (16-step) digitally controlled oscillator (DCO) that uses waveforms including triangles, sawtooth, squares of different widths, and some unusual pulses, plus various combinations thereof.
