This isn't terribly scientific, but if the FM voltage goes below zero, the
VCO's phase reverses. I think Juergen refers to this as reversing the spin
of the spinning wheel. Sonically - it's a richer, fatter sound. I've built
a couple of Thru-zero VCOs from Electronotes. They are definitely worth
having!

What's cool about "through zero"? I've heard it mentioned several
times on the list but I still don't know what it refers to...
