Add a jack to control advance direction (forward, back), and another to
reset to preset 0. Sounds like a quantized 50 x 4 sequencer to me<g>.

Is this the same as the Daughter of MOAS sequencer you mentioned in April
(minus some pots)?

It is not D-MOAS. It is sort of a spin-off. In a way, it is a
pico-sequencer.

Can you ship it by next week? LOL

I'll take 2!

Or, a 1 channel sample+hold w/memory. You could use MOTM S&H for this by
sampling the incoming voltage and then setting the clock input to nothing.
Of course, you don't have any memory.
