In this video I will be showing how to calibrate my KVP (Korg Voltage Processor) module.
While I test and calibrate the tuning of all modules, re-calibration may become necessary when the settings get too far out of whack.
I will give some helpful tips as well as a detailed step-by-step explanation of the calibration process.

This video is of a technical nature.

0:00 Intro, Helpful Tips, Setting Up the Keystep Pro
KEYSTEP PRO: Global Setting CV Base Note = C-2
2:28 V/OCT to Hz/V Calibration
Be sure to trim FREQ with the "low C" note
And trim WIDTH with the "high C" note.
7:01 Hz/V to V/OCT Calibration
Be sure to trim FREQ with the 'A' note
And trim WIDTH with the "high C" note

Keep in mind the KVP is an analog signal converter, controlling an analog MS-20 synthesizer.
And when converting Hz/V to V/OCT, we may be also using the MS-20 to control yet another analog VCO device.
Given these things, the pitch won't be absolutely perfect - but the base frequency and tracking should be well within musically acceptable margins."
