Ahoy chaps,
Just need to clarify something which I am only 80% sure about:

Are all the voltage steps on a 1 Volt per octave keyboard 83.333mV apart? or 1/12 of a volt apart?
E.G. does it go 0, 83.3, 166.6 etc.

OR

Does one octave have 14 steps, with a double step between B and C, and E and F?

I'm pretty sure it is the 1/12V or 83mV step version, I could take apart one of my synths to check Laughing but I'd rather just ask someone who knows Wink.

Yup.

Even E and F, B and C; the notes without a black key between?

As I understand it, it's 1/12 of a volt per semi-tone, E to F and B to C are the only white notes a semi-tone apart, other white notes, e.g. C to D, are 2 semi-tones or a whole tone apart, so would be 2/12 or 1/6 volts
