Hi, I noticed recently that some of my Waves Plugins like Curve Equ, Curve AQ, IDX (among others) are missing the Side chain option. Vocal Ridr is fine. Even going back to a project where I have it engaged, its not showing up in the interface.
I did check and fix permissions and ran all diagnostics via the waves Central App - then reinstalled the Plugs - still no side chain. Very odd.
