knob for pan pot

Hello,
I am checking how to setup a pan pot with center as default.

thanks

I know this is a basic question, but I haven't find any information about it on the manual.
Been reading the knob properties many times.
Evidently there is something in the Lemur language I still have to learn, could you please help me ?
A knob to control panning, that's it.

I think what you are looking for is the "bipolar" setting....
