After buying my first vco, I noticed that something was not right. When the tune is at zero, in zero range, produces a note! it is in the range 1 or 2, already produce other notes.

Found on the web that can be calibrated. I tried to calibrate through the P8, P7 and P9, but it seems to be the same or worse.

I buy today a multimeter (voltimeter) to adjust the V/Oct, but i dont know were i put the positive and negative wire.

I only want that VCO on range 0 produces a C2; on range +1 produces C3, on range +2 produces C4, etc...
Because when i increase the range, high mid tone or one tone....

I think this its a descalibrated VCO, no?

Cheers

Just a thought before you try that.
Are you using a midi/cv convertor? It may be that that is out and not the vco.

Yes, Im using a kenton por solo mkII. 

The fine tune is at 0. I think the problem is really with the vco.
If the problem was with converter, the tune dont high a note when i increase the range....
