Casio CZ/ VZ/ FZ - Pro Series

Hi

they are indeed similar, reading out a sine table and vary readout 
speed to stretch or clinch the resulting waveform. I had a look at 
the patents Yamaha held on this technique....
What Yamaha calls FM originaly is Phase Modulation, the difference 
between FM and PM is, that FM is influencing the read out speed of 
this table steadily and Phase Modulation does this only as long as 
the modulating waveforms is changing.  
As far as I know, when it comes to the CZ, Casio is using those 
readouts to create Waveshapers instead of Oscillators, it's possible 
to do similar things with newer FM-Synth by tuning fixed oscillators 
down to 0Hz...
When it comes to iPD, I created a little (unfinished) conversion 
tutorial that explains how to convert sounds between DX and VZ 
Synths, you should find it in the files section of this group.

...Summa
