Just like it does in Scene or Stomp views. When in GigView (which is where I live when performing live), tapping the name of the preset at the top should behave the same way as it does everywhere else.
The idea of Gig View is that you’re gigging and using mainly your feet, so one might touch the screen unwillingly.
I wouldn’t want this during a gig but one may put it in the device options.
Interesting thought but I hope one’s feet aren’t anywhere near the top of the screen! Additionally, you’d probably have to be barefoot to get anything on the screen to react. Which, funny enough, our occasional sax player does. She only plays in bare feet.
