MOTM

Very interesting!!

So if I feed two S&H from a single noise source and clock them from
the same gate/LFO (or whatever) i'll more-than-likely get the same
held CV value?

I didn't think that analog was *that* accurate! I'll be trying this
out first chance i get.
In which case, i *can* see why you'd need more than one noise source
of the same type.

In my more arrogant moments I sometimes fool myself into thinking I
have this whole analog thing "licked" (as you Americans like to say),
so it's always nice to learn something new like this. Thanks!
