Pro Q3 sidechain question
You still need to set a dynamic band to react to the external side-chain. You can do so by expanding the dynamic menu via the "Auto" button at the top and select the external side-chain.

I'm running Fab Filter Pro Q3 with Digital Performer.
I'm not finding any tutorials about using the Pro Q3 Sidechain with Performer.
Specifically, I'm Mixing a lead VOC trk with heavy background vocals on a separate trk. I want to duck 500Hz on the backgrounds while the lead VOC trk sounding.
So, I set up bus 1 on the lead VOC trk to feed the Pro Q3 sidechain on the background trk. Then, in the sidechain box on the Pro Q3 inserted on the Background trk I chose bus 1.
So, the lead VOC should now be triggering the Pro Q3 on the background trk. Is this the correct way to patch the sidechain ??
