I think you unfortunately put yourself in a bad situation.
First you have to understand what calibration is about, because you’re mixing up two things.
The calibration procedure for a CV source (Reaktor + your audio interface) consists in measuring how a well-calibrated VCO reacts to a change in the voltage emitted by the CV source. We need such a procedure because audio interfaces are not designed to generate accurate CVs, just audio. So the audio interface emits a constant voltage, this voltage is converted into a tone by the VCO, and the pitch of the resulting sound allows the interface to deduce the exact value of the voltage it generated.
What you saw in this video was not someone calibrating a Moog. The Moog was already factory calibrated. What the video showed was Reaktor+the audio interface being calibrated!
The calibration procedure for a VCO consists in sending voltages (1.000V and 3.000V for Braids) from a well-calibrated source to the VCO, and adjusting its input circuitry so that they translate into the right note. Note that Braids is factory calibrated: you did not have to put it in calibration mode.
Trying to get both Braids and Reaktor to calibrate at the same time is like trying to weigh a bunch of bananas on a broken scale: you can’t know the weight of the bananas because the scale is broken, and you can’t fix the scale and check that it’s repaired because you don’t know the weight of the bananas.
You can’t calibrate Braids because your CV source is not accurate, and you can’t calibrate Reaktor because your VCO is not calibrated.
So here’s how I would proceed:
- Get a calibrated CV source to calibrate Braids. Do you have any module able to generate an offset (like Shades)? If so, it’s only a matter of getting a cheap volt-meter to send the right voltages.
- Only once Braids is calibrated, you can use the calibration procedure on Reaktor to calibrate Reaktor.
