I'm trying to feed an external input into Pro-L and Pro-L 2 both in Cubase 10 and Cubase 10.5 and I don't see the limiter responding to the external signal at all...

I tried to see if it's something wrong with Cubase, but I can get sidechain going on Pro-C and Pro-G as long as I enable the external input function, but there is not function in Pro-L (1 or 2) so I can't get it to sidechain limit the way I want it to...

Am I missing anything?

Just a little update,
I tried using sidechain in Ableton Live and again was not able to get sidechain to work in Pro-L.
I was able to do it on Pro-C and Pro-G but not L....
Any thoughts?

Hey,

My L2 isn't responding properly to sidechaining either! So frustrating!
