Controlling faders

I can’t seem to control my faders in Cubase 10.5 w CC121. I can move the faders in Cubase with the mouse(and the CC121 responds accordingly), but can’t get the faders in my project to respond to movements on the CC121. Also, I can’t seem to do CC7 volume moves in midi or audio.

Im assuming you installed the CC121 driver?

That includes the driver and the extension that runs the driver for Cubase specifically
