Thank you very much, Hellmuth. I haven't tried myself randomizing CZ. 
Those who tried like you seem to have found CZ's exceptional behaviour..

Waveform / Modulation:
CZ's waveform and modulation mode are represented in two-byte SysEx. 
Select wave1, wave2, wave2-enable-flag, and Window Function, as usual. 
Ring/Noise Modulation is represented in bit 2-5 (My book mistakenly describes 
it as bit 1-3). These 4 bits mean the 'Structure,' in my terms.

Vibrato / Detune / Multiple Sustain Points: 
Just tweak their usual SysEx data beyond the official range.

Try above and ask me if it is still unclear.
