The Kawai synths are strictly limited to the standard harmonic series, 
though multiple sources can be stacked and detuned.  The Kurzweil K150
permits inharmonic tuning, but I think the relative frequencies are fixed.

As far as I know, only the Synergy permits truly independent pitch 
modulation per partial.

I think FM is sorta easier to deal with for that sort of thing.  I think
the TG77 (hmmm, I've been looking for one) has one pitch envelope per 
voice but has adjustable depth per operator.  Seems like a reasonable
compromise.  And of course with FM it's quite easy to make everything
subtly aperiodic/inharmonic.
