Certainly the most important ones. :-)

Here's a little brainstorming:

A divide-by-four (sub-suboctave) circuit could provide a way to tune 
the low and high ends of a 4 octave range against a reference tone.

How about using a digital keyboard as a tuning reference? Tune the 
VCO until the beating (of VCO vs DCO) is minimized.

Peterson Strobotuners have like 0.1 cent accuracy, so there's another 
potential tool.

None of the above would necessarily help one to calibrate a 
MIDI-to-CV converter, though. Well, I said it was the storm of a 
little brain. ;-)
