There's more to the sound than just the Autotuned or pitch-shifted
signal. To make the 'phasey' sound the pitch-shifted and original
signal are mixed together, and the result is a lot like the sound out

Your "detecting a wavelength of perhaps 0.7 cent off" caught my eye,
as the Hammond tone generation is mechanically tied to the 50Hz or
60Hz power frequency, and I don't think the line frequency has ever
been regulated as accurately as 1 cent (1/100th semitone). For
accurate recordings, you'd need
I'm pretty sure an instantaneous [audio] voltage (or a number in a
stream of PCM values) represents a pressure differential, and not
displacement. A loudspeaker driver in air (within its rated response)
is constrained by the air, above its resonant frequency (at the low
end of its frequency range
I've used the $400-or-so Rigol model (I forget the number), the
interface is a bit clunky as one might expect with all the menus and
features, but it works well. The "traditional" scopes only go to 8
bits, or maybe 12 bits at the most. As always, look carefully at the
specs.
A lower cost
