Audio Plug-Ins Guide76
With external key side-chain processing, you
trigger dynamics processing using an external
signal (such as a separate reference track or au-
dio source) instead of the input signal. This ex-
ternal source is known as the key input.
With side-chain filters, you can make dynamics
processing more or less sensitive to certain fre-
quencies. For example, you might configure the
side-chain so that certain lower frequencies on a
drum track trigger dynamics processing.
Dynamics III Side-Chain
Controls
The controls in the Side-Chain section let you
toggle the side-chain between the internal input
signal or an external key input, listen to the
side-chain, and tailor the equalization of the
side-chain signal so that the triggering of dy-
namics processing becomes frequency-sensi-
tive.
Dynamics III Side-Chain External Key
The External Key toggles external side-chain
processing on or off. When this button is high-
lighted, the plug-in uses the amplitude of a sep-
arate reference track or external audio source to
trigger dynamics processing. When this button
is dark gray, the External Key is disabled and the
plug-in uses the amplitude of the input signal to
trigger dynamics processing.
Dynamics III Side-Chain Listen
When enabled, this control lets you listen to the
internal or external side-chain input by itself, as
well as monitor its levels with the Output meter.
This is especially useful for fine-tuning the
plug-in’s filter settings or external key input.
Dynamics III Side-Chain HF and LF
Filter Enable Buttons
The HF Filter Enable and LF Filter Enable but-
tons toggle the corresponding filter in or out of
the side-chain. When this button is highlighted,
the filter is applied to the side-chain signal.
When this button is dark gray, the filter is by-
passed and available for activation.
