Casio CZ waveforms?

[Halon]

Hi. Was wondering how i would go about to make the waveforms you find in the CZ line of synthesizers e.g SawSquare, DblSine and Reso waveforms. They are all based on Sine waves i believe, so a waveshaper would do the job i guess?

Cheers.

Casio used a method called "Phase Distortion Synthesis" for the CZ family. This video demonstrates the math behind it. Make sure to watch the follow-up video as well!

Hi, saw this post so thought I would post this. Three methods of "Phase Distortion" . The cool thing about the Heterodyne and Allpass methods is you can use and external sources for your input waveform.

Later then, BobF

Enjoy and PLEASE comment.....

I’ve attached the Casio patent for the technique.

I personally find it fascinating what was being achieved with the relatively limited digital electronics available back in the 80s.

Enjoy!
