Not mine. Over the 4 octave range 0 to 4 volts, my actual measured
variation between octaves is 9mV when first turned on and 13 mV after warm
up (worst case). Not that it matters, bit the variation from whole number
volts on "C" notes is shifted as much as 20 mV. Now, I am no meter guru
(but I know one <grin>), these are just the numbers I am getting using a
Fluke model 77.
Just for s∗∗ts and grins, I took the same meter over to the CV output of my
beloved MicroMoog. Over its keyboard range I found actual octave variation
as high as 57mV. So, at its worst spot, the Volt / Octave output of my
Pro2000 has 25% less variation than my MicroMoog.

Ah yes. I see it. Page 30 in the "USE of the VCO" section. Sorry for the
wasted bandwidth. I am guilty of reading only up through the end of the
calibration section. I figured I would need to read that "use" part once I
had a working one to use. WRONG. Duh! slapping myself with a wet noodle.

Nope. Checked them today and all the wiring is correct. I think the
problem is my lack of understanding of sync. Your blurb concerning correct
sync operation should help. Now, back to testing....
