Create a Sidechain-Style Effect with an LFO

A Pulsing Sidechain-Style Effect

Sidechain pumping is a classic EDM effect.
Here we will recreate that sound using an LFO.

Sidechain compression commonly controls volume,
but this approach can change several values at once, including filter and oscillator parameters.

How to Create the Sound

Setting Up the LFO

• 1. Select the LFO.
• 2. Select Sync to synchronize it with the tempo.
• 3. Set the LFO rate to quarter notes.

Applying the LFO

Apply the configured LFO to volume.
This creates an effect in which the volume changes on a quarter-note cycle.

Applying It to Other Parameters

From here, you can experiment freely.
Try Filter, Reverb, Phase, Detune,
or apply the LFO to other parameters of your choice.

That completes the sound!

Frequently Asked Questions

Q1. How does sidechain compression differ from an LFO-based sidechain-style effect?

Sidechain compression commonly controls volume in response to a trigger. With an LFO-based effect, you can also modulate multiple parameters at the same time, such as filter, reverb, phase and detune, to create more complex sounds.

Q2. Why sync the LFO to the tempo?

Tempo sync aligns the pulsing effect with the beat. Setting a rate such as quarter notes produces a consistent rhythmic sound that can be useful in EDM.

Q3. Can beginners create a sidechain-style effect?

Yes. Select an LFO, enable Sync, set the rate to quarter notes, and assign the LFO to the desired parameters. The video tutorial in this article walks through the process.
