[sdiy] 'equally tempered' vco

[Laurie Biddulph]

Exactly...

The VCO has 3 basic sections:-
1) front-end mixer
2) core oscillator
3) wave shapers

The front-end mixer has been tailored to a 1V/Octave range and this, I 
believe, makes it equally tempered. Replacing/modifying this front end would 
allow other temperaments to be catered for if I am not wrong.
