That'd be the way I'd copy the usual digital implementation. maybe demux
the incoming pulses into even and odd, and drive two similar chains. that
is:
even pulses reset ramp1 and sample ramp2, odd pulses reset ramp2 and
sample ramp1. these could be sampled by separate analog shift registers so
that a weighted average of the last several readings could be used to drive
the VCLFO. I geuss that's not much different than running one chain, just
thought some timing conflicts might arise, resetting and sampling at once

The other thing that occurs to me is that the slope of the sampled/reset
ramp could be voltage controlled itself, then all that remains is to
maximize
the sampled CV by varying the slope CV. maybe random voltage whose time
correlation increases as the sampled CV increases, zeroing in on the right
slope
to have the ramp reset closest to when it'd naturally reset.
It'd probably take many more taps to get a good signal, but I like this
version
better, it's more like a person in way, the mistakes it'd make would be nice
ones. the sampled CV would be maximized just as well at multiples of the
base
frquency, so it'd work reliably over a wide(r) range
