Quick question: How does one set the corresponding MIDI ports to Not Connected?

Seems obvious and sure I have done this before, but now can’t find a way. Studio Setup/MIDI port set up. Should be there!

Hi,

Studio > Studio Setup, choose the device (like Generic Remote or Track Quick Controls) on the right side clock the MIDI Input or MIDI Output drop-down menu and select Not Connected from the list.
