analog storage sequencers

>Would it be reasonably feasable to construct a sequencer that was a
series of sample-and-holds, so that one could step through the
sequence entering notes directly from a keyboard instead of dialing in
pots?  

I love the term "reasonably feasable!"

My .02 worth would be a cheap A/D-latch-D/A. Possibly 1/2 a dual opamp input
to a resistor pack to form an A/D then to something like a LS373 latch then
to a DAC using the other half of the amp and another resistor pack. This
wouldn't be the best, but it would only need a dual opamp, 1 latch and 2
resistor packs per stage. Of course, there would be additional stuff for
clearing the latch, etc.

Since all of this sounds far too easy, please tell me what I'm missing
here....
