Assigning a midi CC to a fader

[tigerman]

Hi, i would like to assign a fader of my master keyboard to the mater aux fader in order to control volume of the entire project, so i do not have to use the mause all the times.

that "link" should be indipendent from the track i have selected in the edit window.

Is it possible? I'm coming from Logic so i'm still learning, i've browsed all pro-tools menu but i can't see anything related do midi cc, do i need a compatible control surface in order to do that ?
No way to have just the volume on a fader controlled by a midi cc?

thanks
