Hi!
Same Problem on my side last week 10 min after the begening of my show while recording multi pistes 18 track at 48K , just before the show i’ve turn the RTA on ??……my be this was the trigger of the prob . all faders / soft / was still working but nothing else in the screen everythings was frozen no more control . after the show i’ve shot down by the on /off switch and everything was back to normal . little bit spooky
