To do "true" Chowning Frequency Modulation Synthesis (ala Yamaha DX-7) you
need a VCO where the FM can send the oscillator 'through zero.' In an analog
VCO this is tricky.
Someone please correct me if I'm wrong.

OK, time to show my ignorance. I seem to recall this explained before
but it didn't
stick. What is so special about a VCO with through-zero FM?
