Yes, you’re right
“Gain Reduction LED
Indicates the amount of compression of the signal.”
But only appears at channel settings window. Until N8 you could see a gain reduction LED working on mixer window as gate state LEDs, now there’s nothing. You can see the gain reduction in the meter at the top if you select view, but for gate there’s nothing and is very uncorfontable not to see gate status in the whole mixer view.
