Part of Casio's series to use their unique SD (Spectrum Dynamic) Synthesis. It's pretty much just a subtractive synth with a real analog VCF, ADSR envelopes for the DCA and VCF. The LFO only modulates pitch (vibrato) and volume (tremolo). The 32 oscillator waveforms are a bit of a well-kept secret. They vary from highly nasal or "slender", resembling saw or square waves, while others possess an unusual metallic tone and incorporate white noise. The exact mechanism behind the generation of these waves remains enigmatic, but specialists propose that they comprise multiple harmonically-rich pulse waves at varying octaves, alongside a ring modulator and an analogue noise source.
