Sidechain cog disabled
It's possible you're running a very old version of Pro-Q 3 that does not include the extra dynamic settings yet. Could you see if updating to the latest version resolves the issue?

In this how to the ableton live instructions seem old.
If you set it up this way, the sidechain doesn't work:

Apparently, you have to click on the cog to activate the external sidechain. Hoiwever, I made a dyanmic EQ and the cog is disabled. Any ideas why?
