As far as I know there are two issues at play for HZ/V/Oct.

1 - The octave scaling everyone talks about. Technically you can calibrate one octave between the 101 and another V/Oct synth. You can luxury of getting say, a low C and a high C to be 'in tune'.

2 - Each note within that octave has to scale logarithmically, and this is actually the root of the problem. It's a separate conversion altogether. A V/Oct synth scales up in a linear fashion. A HZ/V/Oct synth scales up in a non-linear fashion, logarithmically, so the octave tuning has no bearing on what happens with all these notes in between. The 101 exponentially scales as you move up from one note to another so it will always be way out of tune until it reaches your calibrated 1.2V, then it's way off forevermore past your calibrated octave.
