[sdiy] VCO Accuracy

[Seb Francis]

Within 1 cent accuracy is good to aim for, although you are unlikely to 
get there with analog.  A good MIDI to CV should be capable of this - 
that's within ~1mV at 1V/Octave.  Of course you'll need a good voltmeter 
to actually measure this.  I doubt any analog VCO (even MOTM) will be 
much better than +/- 5 cent across the useful musical range.
