I want to sidechain 3. party plugins
Stephen Pickering commented
I agree. AFAIK, the only plugin that Adobe allows this capability is Beatrig Sidekick Extended 6. So, the functionality does exist. But any DAW can easily perform this same task. Without the Beatrig Plugin, there are two, poor options.
Rendering to Audition or any other DAW is too time-consuming for such a simple task. Utilizing Essentials Sound hard-baked keyframing is not the on-the-fly audio ducking that editors need in a changing, creative sequence.
