The problem is that everything on a modular is relative. Meaning, even if
you calculate the precise voltage at 1v/oct necessary for that range, you've
still got to deal with the knobs on the VCOs and its own inherent drift and
nonlinear issues (present in any analogue system). To get precise control
like that you'll have to do some precise calibration EACH TIME you turn the
stuff on, as well as (IMO) wait a good 1/2 hour before doing so while the
units warm up. To measure it you need a frequency counter, a device which'll
tally pulses over time and give you an accurate measure. You could do it on
an oscilloscope but it wouldn't be as precise.
