Using a Filtered Input Signal for Side-Chain Processing with Dynamics III
2 Ensure that the External Key button is disabled (dark gray).
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 side-chain input so that only specific frequencies within the input signal trigger the plug-in, use the HF and LF controls to select the desired frequency range.5 Begin playback. The plug-in uses the filtered input signal to trigger dynamics processing.6 To fine-tune side-chain triggering, adjust the plug-in controls.
