The A110 _is_ a Moog VCO its quite the same circuit, which was used in
the late seventies, early eighties for all Moog synths.
I don't think that the VCO itself is the interesting part of this MF. It
is the envelope follower and the idea to create a pulse wave out of the
input signal and to use this for hard-syncing the VCO (crossmodulation
with external audio is more common). This sounds really great and is
definitely a patch, you should try with a modular synth.
It requires a decent preparing of the input signal, and I think heres
the spot where the engineers of Moog did a good job.
