I've not noticed this with two that I've worked with.

Tempered keyboard tracking you mean?  Yeah, that would makes sense. As you
mention, the Buchla is not a 1v/oct machine, more on the order of about
1.2(ish) volts per octave - and that's on any module he's made. But having
the ability to track a keyboard (no matter what voltage is required to do
that) when the attenuator is locked into a certain position (like full CW
for instance) is a sold concern. If the inputs on the 260 aren't scaled as
such that's really weird, especially cause the faceplate graphics for the
internal barber pole addresses standard western semitones in its
nomenclature. hmmm...
