Sound Field Plug-Ins : TL AutoPan : Using TL AutoPan : Using the Side-Chain Input

Using the Side-Chain Input
The Side-Chain Input option in TL AutoPan lets you direct audio from another track in your Pro Tools session to the Envelope Detector. This is achieved by sending the audio from the desired channel to a bus and setting the side-chain input on TL AutoPan to the same bus.
