Apparently yes. I ran into a website somewhere describing a Moog synth
at
some college of music (maybe even UC Berkely?). Moog of course didn't
provide S&H modules except on a custom basis, but this web page
describes
several custom modules that they had made to round out the system. One
of
them was, surprise! - a triple S&H which passes the output of one to the
next, to achieve a pseudo canonic output. I think that all the inputs
and
outputs can be used separately as well if desired.

I already have one of these planned to DIY. Great minds think alike.

OK I over-simplified. (BTW: taxes done, I'm back to my normal self)

You need to "stagger" the clocks (ie delay the edges) wit respect to the
clock
into the *first* stage. JH uses cascaded 1-shots, and crude but
effective
solution :)

You can also use a "multi-phase" clock (ie clocks are delayed by 90
degrees).
