         <span class="form-message">The following setting controls how Pollux determines when to follow Castor. The intended behavior is that when no cable is attached to Pollux's pitch CV jack, it will follow Castor's pitch. The module detects this condition by seeing if the input jack is reading 0 volts. Sometimes due to analog conversion errors this threshold needs to be adjusted. Lower thresholds may lead to glitchy behavior as the noise measures above and below the threshold, and higher settings may lead to Pollux ignoring the pitch CV input on lower notes.</span>

During manufacturing, we measure the ADC's response to determine its gain and offset error. We save the calibration data to the device but we also keep a copy of it- if the settings below get lost, corrupted, or otherwise messed up, you can use the restore button below to load the values that were originally on your device. If the button is greyed out, then we don't have a copy of your module's calibration data ☹️.</span>
