Well I thought I knew what this was going to do, and would be easy, but I simply can't make this do anything.
I have two tracks.
Track 1 - with Pro-Q3 with sidechain enabled and sidechain selected in the analyser mode. I have also set up an EQ point with dynamic EQ.
Track 2 - I have another audio track sending audio to that sidechain.
I was expecting to see the Track 1 EQ 'ducking' controlled by track 2. But absolutely nothing different happens and the EQ ducking continues to only be affected by Track 1's own audio.
So what am I doing wrong?
I followed to the letter the help file here: www.fabfilter.com/help/pro-q/support/externalsidechaining
