   Sonically it means that you just (finally) get all the effects of
   ordinary linear FM. 

Hey Juergen!  I think you're possibly the only one on this list who
is set up to try this out...  (I surely am not!)

The best Hammond organ sounds I've heard on the Yamaha DX-7 have all
used a patch where several oscillators are mixed together and then FM
modulate a single final oscillator, where the final oscillator is set
to some fixed low frequency, around 1 Hz.

I've always thought this was very clever, using FM not for warping a
basic sine wave but as a chorus-like effect that provides animation
and some soft clipping.

Have you ever tried this with one of your through-zero VCO's?
Running, say, a Wurlitzer through it?
