Pro Tools

Open Pro Tools and start a new empty session.

Create two audio tracks that we'll use as main track and side chain track. Add audio files to both track.

Open the Mix window to display the tracks with their Insert slots and Sends slots.

In the first 'Sends' slot of the side chain track, choose 'Bus 1'. The track view for Bus 1 will open: set its level slider to 0.0 dB

so the bus actually produces audio!

In the first 'Inserts' slot of the main track, choose EQ > FabFilter Pro-Q 2.

Now, in the 'Key Input' menu of the plug-in interface (just above the FabFilter logo), choose bus > Bus 1 instead of the

default 'no key input'. Now, the audio from the side chain track is routed to Pro-Q 2's external side chain input via Bus 1.
