MOTM

Your could mathematically describe your VCA method
as VCO_waveform1 x HWR(VCO_waveform2)
where HWR means half wave rectifying.
In other words, it's similar to RM (ringmod), but with the
negative half of one RM input signal clipped.
(VCA ignores negative CV).
If you want to make an analytical description of the resulting
spectrum, this should be possible: Harmonics of waveform1
(as usual), and harmonics of clipped waveform2 (still
possible with textbook methods), and then get the f1+f2 and f1-f2
of each combination of harmonics.
With one signal being a sine wave (the one that goes to the VCA's
signal input), it's quite easy to calculate.
