Hello

I doubt really, that this video is live at all. It is a TV-show, so it
might be playback or at least halfplayback. To make the vibrato in the
end of the sound he would have to touch the Modwheel, but he does not.
So this is fake for sure.

And if it was live: You don't see his hand on the keyboard at all. He is
playing the octave jump with the right hand, and you cannot judge what
he is doing.

Soundwise I am definitely sure, that this is a simple portamento. The
original Minimoog did not have envelope modulation for the VCOs.

If you want to do it with an envelope:
* Set the ADSR to A=0 D=4 S=10 R=0 (values from 0 to 10).
* Connect the ADSRs inverted out and feed it into CV2 input of an A110
or A111.
* Listen to the VCO continuously (VCO out direct to your mixer/headphone).
* Turn up CV2 potentiometer. => now the VCO should be much lower if you
press a key and return to normal frequency if you release a key.
* Now adjust CV2 to make the VCO jump down for one octave if you press a
key.
* Then turn Sustain to 0 => Now each keypress should cause the VCO to
make a slide from one octave below to normal tuning.
