I did there as well. Posting here as well because these dudes know their stuff too and it may not be an issue specific to this controller. Making sure i'm connecting everything properly and expecting the right outcome.

just mess with every option and check every value, if you don't have one just keep playing into an oscillator C3 and C4 to compare whether the pitch is the same but an octave above (obviously you don't have to tune it to an actual C, just compare an octave.)
Don't have a multimeter. And i tried the C3 to C4 and the pitch is not an octave. It's off from key to key and that's the same for a full octave as well.

Is it a very sharp D Flat according to the tuner or according to your ears?

right, now keep doing that with every output and every setting on every output to find what's offsetting it, or your keyboard seems to be truly not calibrated to 1v/oct.
a manual would help.
Alright, i'll mess with that some more when i go home for lunch. There's a manual it's just pretty basic but maybe i'm missing something:

Also is it off by the same amount between all of the octaves?

Bout to hop on a plane but that would be nice to know for troubleshooting

I'll have to take a closer look at that on my lunch break.

Yeah if that's right (manual won't download because I'm on the train and my service sucks) then there's your answer.

Hmm, but how are these people using VCOs that track at 1v per octave using it then?
For example, a guy on an old muff wiggler thread posted his signal chain and is using this with it which tracks at 1v per octave

Either they're not fussed on accurate pitch tracking or you could feed the signal into a quantiser (losing the gliss functionality probably)

I heard they use an instagram filter for the missing cents.

this sounds in tune, no?

and the guy in this video
[youtube]http://www.youtube.com/watch?v=QRanI6FVw2o[/youtube]
is using this
looks like there is a "variable 1v/octave adjustment" knob. Is that how he is calibrating it to track properly?

First video is only the ribbon which is continuous rather than using discrete voltages like the keys so you can play in tune no problem.
That module does seem to have an inbuilt attenuator/amplifier for the input, which might work? I'm too lazy right now to do the maths
