Hi
think it's the so called "hardness" parameter of the Nova synths familiy
that enables the soundprogrammer to make CZ like sounds. That modulateable
paramter allows to reduce the waveforms of an oszillator to a sinus and thus
working like the DCW parameter of the CZ. You find the same parameter on the
AN1x, but I don't know if it's possible modulate it by envelope or LFO. That
way it's probably possible to create some CZ like sounds. But missing the
complex envelopes and the resonant waveforms, that would be at least needed
in front and not behind of the ring modulator to create some of the realy
interesting CZ sounds, it's probably a bit limited.
Other then that you can do a lot of CZ like sounds with the FS1R. If you
look at the Yamaha patents you'll recognise that Phase Distortion or Phase
Modulation is the same technique Yamaha is using in their "FM" synths.
Unfortunately it's not possible to take a look at the programming of the CZ
to see how they implemented that algortithm...
