Calibration

The hardware needs to be calibrated to correctly track v/oct pitch.

To re-calibrate your hardware:

  • Press and hold shift for 5 seconds to start the calibration. The LED will light and then start to blink.
  • First give it a 1v (C1) signal to cv_5 and cv_6 and then press the shift button.
  • The LED will start to flash more quickly and is ready for the next step.
  • Give it a 3v (C3) signal to cv_5 and cv_6 and press the button again.
  • It will now return to normal mode with new calibration settings.
