linear vs exp FM

[Paul Nugteren van]

I was wondering if I could live without the FM mod-depth controlled 
by an env on the jp8, anyone tried to do wire crossmod on say env1 on 
an jp8 like on the jp6?

The polymod section env on a p5; what did it control; osc2 freq and 
FM depth? I've read somewhere that the p5 could do to pulsewidth mod 
on osc1 by osc2 Is that right?

And then the last; all synth manufactureres have used exponential 
keyboards in their synths except KORG wich has used the V/Hz norm. So 
was KORG the only one with linear FM (MS20?)? I don't understand what 
the difference between lin FM and exp FM is actually; the oscs in a 
synth are controlled by a CV from the keyboard which increases it's 
output by V /oct right? The two oscs in say a jp8 track each other 
quite evenly so why has the jp8 still got exp FM? Does it sound very 
much different than linear FM?


Thanks,

Paul
