The Key button and the Dynamics Sidechain inputs
You can use external signals to trigger the Dynamics section. This is done by connecting an external signal output to
the Sidechain inputs on the back of the Mix Channel or Audio Track rack device.
The Sidechain inputs.
When a cable is connected to the Sidechain inputs the “KEY” button is activated automatically and the Dynamics
section for the channel will now be “keyed” i.e. triggered by the external signal instead of the channel signal.
For example, you could use a drum loop to trigger the gate for a channel playing a synth pad to create rhythmic chord
effects.
See “Using compression sidechaining” for a description of further uses of sidechaining.
About Gain Reduction CV
The Gain Reduction CV out connector on the back of a Mix Channel or Audio Track rack device can be used to mod-
ulate other parameters with the amount of gain reduction applied by the compressor/gate. The gain reduction CV out
can be used as an envelope follower as the CV follows the dynamics of the original signal.
For example, try using gain reduction CV to control filter frequency for “auto-wah” effects.
