Cubase questions from a Logic user

Two more questions…

I’m trying to use QuickControls in the Inspector, but when I enable the Learn function, it doesn’t see my incoming fader movements. I wonder what I need to to to fix this?

Also: I’ve spent 10 minutes trying to find out how I set up a send (which I can use to send the signal from an instrument channel into a reverb), with no success. Advice would be highly appreciated!
