20 | Setting up the pedals and the audio connections
What if the pedals do not behave correctly?
If needed, you might have to calibrate the pedals to use their full range of values,
without any ‘dead spot’. Also, this procedure allows to choose a pedal’s polarity,
in case you are using a pedal working in reverse.
1 Go to the Settings > Controllers > Foot page.
2 Touch the Calibration button in the area of the pedal to calibrate, to make
the Pedal/Footswitch Calibration dialog appear.
3 Fully press the pedal down, and while continuing to press touch the top
(highlighted) button to confirm the maximum value.
