I can get mostly there with two lowpass gates and a dual trigger delay.

Set the two LPGs in the signal path serially, first one set to
lowpass, second one set to VCA, send each the output of half of the
dual trigger delay, both halves of which are being triggered from the
same source. Set the Lowpass trigger as short as possible, set the VCA
trigger longer to taste.

Examples here:

and here:

Both use two plan b model 15 oscillators, one as modulator one as
carrier, into the 101-2 LPGs in series. The timbre of the oscillators
going into the LPGs is just as important to the sound as the character
of the LPGs themselves, IMO.
