[sdiy] Analysis of frequency variation in analogue synths

[Paul Perry]

Oh, I agree entirely.
I was just saying, that beating with a rock-solid source would at least give
an indication of longer term variations.
Anything psychophysically interesting, would presumably involve jitter of
some kind in the 10mS -500uS range. And time dependent structure in the
jitter error would be where the effect - if any - would originate.
