Using Dynamics III Key Input for Side-Chain Processing
To use a filtered or unfiltered external key input to trigger dynamics processing:
1 Click the Key Input selector and select the input or bus carrying the audio from the reference track or external audio source.
 
2 Click External Key to activate external side-chain processing.
 
3 To listen to the signal that will be used to control side-chain input, click Side-Chain Listen to enable it (highlighted).
 
4 To filter the key input so that only specific frequencies trigger the plug-in, use the HF and LF controls to select the desired frequency range.
5 Begin playback. The plug-in uses the input or bus that you chose as an external key input to trigger its effect.
6 Adjust the plug-in’s Threshold (Thresh) control to fine-tune external key input triggering.
7 Adjust other controls to achieve the desired effect.
