On the Normal page for a CV channel you get the settings (for pitch you’ll get note and slide params) on the Value Lin page you get a single potentiometer which is the Value of the ‘potentiometer’ ‘dividing’ the voltage between your minimum and your maximum … so that potentiometer should be set to the minimum value which for your unipolar envelope means all the way anti-clockwise
alternatively if your voltage range was -5 to 5v your zero point would be 12 o’clock and so on, so it depends on your settings … simplest conceptually is to use 0v to 5v and set the dial to minimum value … then the modulations from the envelope targeting value lin are all +ve
