The definitive side-chaining plugin

Ducking, or “side-chaining”, is one of the defining effects of modern music. From punchy drums to the pumping sound of big-room EDM, the technique has countless uses and should be in every producer’s toolkit.

Duck makes this effortless and fast. Simply insert it on a channel, and draw the volume shape you want. It’s that easy. There are even preset shapes to get you started.

Duck is also capable of rhythmic gating, tremolo and any other volume effect you can think of. For more control, enable split band mode and adjust the separate low and high frequency controls. And Duck can be triggered with audio from a sidechain input or by MIDI notes, making it easier than ever for hip-hop and bass music producers.

“Perfect for intricate sidechaining. Other products do not come close to the accuracy and precision that Duck has to offer.”

Using The Crossover

The crossover allows you to process the high and low frequencies of your music separately.

Find out how can use this feature to let your music shine whilst still having all that space for your bass.



OSX 10.9 or later (Intel and Apple Silicon); Windows 7 or later. VST 2.4, VST 3, AudioUnit and Protools 64-bit AAX


If you are triggering Duck using audio or midi, rather than using the LFO, you can clean up your audio and avoid unwanted clicks with Lookahead.


Gated reverb with audio triggering

Duck has audio input based triggering. This, in conjunction with the Lookahead feature, makes it perfect for precise design of gated reverb style sounds.

Just place Duck after the reverb on your drum sound, select plugin input from the trigger mode menu in the bottom right, adjust the trigger level, curve shape and lookahead settings until you get your desired gating effect
