You are right, but you will run into other troubles with freq/CV ;-)

You found the right track

The PLL is basically made for what you want to do, but your Problem is, 
that the output voltage is linear to frequency not to octave :-( So good 
luck with producing a lin/log converter....


A second problem: To have a frequency range that produces more exact 
results than a level based system you have to use a wide frequency 
range. The PLL won't follow such a wide range as good as you would like it.
