OK, I'm kind of lost here!
You CAN run audio into both inputs of a S/H module. I used to do this A LOT 
to get a nastier timbre (than one of the four simple waveforms). One of the 
few classic examples of S/H use is to put a saw in to the CV input, and a 
faster square into the clock to get a "staircase wave." Well, there's no 
reason you can't run that clock well up into the audio range, but the output 
will always be a staircase (given the saw input).

Moe is right about the range of the module. I do remember the MOTM S/H 
starting to disappear in the upper audio range, though I forget how high.

I've found there's lots of good stuff that can be done with two or more VCOs 
and S/H and synching -- very odd cyclic stuff. Maybe others can comment more 
specifically on these patches?

I don't remember the sound produced with a mic (preamp) into the CV input but 
I do think it would produce a very nasty lo fi sound, which I gather is what 
you're after.
