Actually, this is a *classic* PLL. The only odd part is the expo-function in
there, which a normal PLL doesn't have.

This is very interesting.  Does this method give the same sound as the 
hard-reset sync that we've all come to know?  (especially when changing the pitch of 
the synced VCO -- lots of radical harmonics, etc.)  I'm guessing that it 
doesn't - and that it has a limited "capture" range, but I'd like to hear from 
those who have actually heard it.
