Pro Q 4 Problems with Side chaining
I use Pro Tools on a Mac Studio. When assign a track to the sidechain in ProQ 4 to dynamically trigger the EQ curve, it reacts to other tracks that are not assigned or bussed to the ProQ 4 sidechain. How can I fix that?

Hi Michael,
If there are tracks coming into Pro-Q 4 these tracks need to be assign to the side-chain bus somehow. You can right click on a bus and choose “Select Assigned Tracks” so you can see what tracks are assigned.
Please let me know if this resolves the issue.
