Hi,
I‘d wish the gate had the same features like the old drawmer gates ds201 :
Source/SC Listen
Ducking Option 
+1
Having a dedicated ducker in the qu was very nice to have. Disappointed it’s not in the SQ as a seperate effect.
FYI - There is a ducking option on the SQ series, but it is located in the channel’s compressor settings rather than the gate settings. It does allow for a side chain input to be selected.
Yes, I only discovered the ducker today after someone else pointed it out.
Great to have, on the odd occasion it’s needed. As would be an expander in the Gate section, of course…
