Can't get the Sidechain to trigger correctly in Logic
hi - I'm trying to use a dynamic EQ on a specific band on my guitars bus, to duck a db when vocals are hitting. I set the ProQ4 plugin on the guitar bus, and within the plug in set the side chain as the vocal bus (I'm using Logic), however the dynamic EQ seems to be ducking/jumping around all the time - even when there's no vocals happening. What am I doing wrong that it's not just triggering the side chain I set?

Did you enable the external side-chain for the dynamic band? You need to enable this per band. When you click the Auto button above the gain of a dynamic band you will see an additional icon for the external side-chain.
