I joined your list yesterday :) 

But I'm not the one to start those discussions from scratch. I rather wait
and see... :)

I'm not that much into math so I'm imgagine the results of synthesis in a
more waveform based way. Basicly Phasemodulation is "better" then FM, since
the carrier frequency isn't changing when being modulated and get's no dc
offset, it also creates a more constant sounding patch on the whole keyboard
range...
That's why yamaha implemented PM instead of FM... 
Also when using another carrier waveforms then sinus you can't use the
modulator as LFO anymore. I experienced that effect on the FS1R...
Anyway, all I wanted to say is, that CZ, VZ and Korg VPM Synths are basicly
as much FM/PM synths then the ones Yamaha created....
Even so they may not have gained the same status DX synths have, the
discussion about those synth belongs to your list as well. Especially the VZ
is interesting, since that synth combines FM with ringmodulation. So the
soundprogrammer can chose if the an oscillator pair is parallel, phased (1:1
FM) or ringmolated.

I think I know Tim from Daves DX List, he's the one with the ATARI users
list, isn't he?
