How to Sidechain in FL Studio 20 – Step by Step Tutorial

If you’re just getting started with music production in FL Studio, chances are you’ve heard the term sidechain or sidechain compression thrown around. Compression is one of the most popular tools used in professional audio recording, producing, and performances. So no matter what genre of music you listen to, your favourite songs are sure to use some sort of compression.

Generally speaking, most compressors work on their own and focus on controlling the output of a single channel in your mix. Sidechaining works a little bit differently, by making sure a particular sound is compressed, relative to other sounds or channels in your mix. In laymen terms, sidechain helps your leading elements stand out while ducking the volume of other sounds that get played at the same time.

If you’re still a bit confused, think of your favourite dance music tracks. You’ll notice that even though they have hard-hitting and catchy bassline synths, the kick drums always shine through and punch on every beat. This is because the producer has utilized sidechain compression in order to “duck” the clashing low-end frequencies on the bassline whenever the kick

In this article, we explain everything you need to know in terms of compression and sidechain. As well as a step by step guide on how to sidechain within FL Studio!

Compression

To understand Sidechaining and Sidechain Compression in FL Studio, we must first cover the basics of Compression, and how to use a compressor. Compression originated in the early days of recording with the goal of maintaining a consistent output from vocalists. It’s a dynamic processing tool that’s used to keep your audio signal within a specific dynamic/volume range.

Essentially, compressors are useful for making your loud sounds softer. So you can boost the overall level of a track while narrowing the dynamic range. Resulting in a much cleaner, and more enjoyable mix.

Using a compressor on your FL Studio audio track starts by picking a volume level you always want your instrument to sound at (never louder, never softer). Then, you’ll set a compression level to determine how sensitive your effect will be. Resulting in every note played too quietly to be boosted into your volume range, and every note too loud to be softened to fit the range. So, your instrument will always be heard within the dynamic range you specified.

Even after reading this, you might still be a bit confused when you’re staring blankly at a compressor on your FL Studio project. So, we’ve outlined some of the most common terms to help you out!

Parameters on your compressor

Threshold

Perhaps the most important parameter on your compressor. Setting the threshold means that any sounds on the track louder than this will be reduced according to the ratio. While leaving sounds sitting lower than this level alone.

Ratio

The ratio determines the intensity of compression for sounds sitting above the threshold. Therefore, at a ratio of 2:1, any sound 2dB above the threshold will be reduced by 1dB. While at a ratio of 10:1, the sound will be reduced by 1.8dB. Therefore, the higher the ratio, the harder the compressor will work. It’s worth experimenting to find the ratio that works best for your sound.

Peak

Adjusting the peak parameter determines how your compressor perceives the loudness of the sound.

Attack/Release

Using the attack parameter on your compression allows you to determine how quickly the compressor engages. While the Release parameter will determine how quickly it shuts off.

Knee

The Knee determines the onset of your compression. Using a low knee on instruments like drums and guitar generally sounds better. While a higher knee placed on vocals can make your voice sound smoother and more natural.

Furthermore, using a multiband compressor can isolate multiple frequencies and compress them, while leaving other frequencies alone.

Sidechain Compression

Sidechain compression differs slightly from compression. It works to control the level of a particular sound, relative to other sounds within your mix. For example, the compression level of your bass track may be controlled by the volume of your kick drum. So, when your kick drum sounds, your bass becomes more compressed. Therefore, both sounds can keep cutting through the mix. Allowing the kicks to dominate the mix without clashing with the sound of the bass and creating a muddy signal. Therefore, providing a pulsating, and rhythmic dynamic to the sound.

Sidechaining has a number of different uses, so today we’ll explore just a few of its most common applications.

Dialogue Ducking

Since the introduction of sidechaining, Dialogue Ducking has been one of the most common uses of the technique. Automatically reducing the volume of music to make way for vocals. There are numerous examples showing dialogue ducking in action such as; when you’re at the supermarket and the music softens in order for somebody to make an announcement; and when the music drops in volume on the radio while the host speaks.

Vocal Mixing

Vocals are consistently the main focus of every song. You want your vocals to stand out, be loud enough, and be heard clearly. If your vocals are getting a little bit lost in the mix, you may be tempted just to turn them up. However, by sidechaining other tracks to your vocals, you can make sure that your other tracks quieten down to make room for your vocals. Letting your vocals shine while minimizing unwanted distortion or clipping.

Letting The Kick Punch

You’ll notice most Pop and Dance songs feature super punchy kicks and bass. Using these elements together without proper separation can be a recipe for disaster. Resulting in clashing frequencies and in turn, a muddy, unpleasant mix. Like the example above, in order to avoid this, you’d simply add a compressor to your bass track, while sending your kick’s signal to the sidechain input. Helping you to clear up the clashing frequencies and really make your kick drum pop!

To achieve a different and more stylistic effect; you can even sidechain other sounds like synths, leads, and even vocals to center your rhythm around the kick drum.

How To Use Sidechain in FL Studio

So, now to the nitty-gritty! How do you use sidechain in FL Studio? There are a few easy ways to sidechain in FL Studio, and we’ll go through 3 different methods you can use to get this done! We’ve even put together a handy infographic below that gives you a quick rundown on how to sidechain.

How to Sidechain with FL Studio’s Fruity Limiter

For the first and most typical sidechain setup, we’ll be using the Fruity Limiter inside FL Studio to sidechain your kick drum to a bass synth. In this technique, we’ll work to compress the bass signal whenever the kick drum plays.

Without any sidechain, your kick drum and bass synth are likely to clash with each other within certain frequencies. As a result, your kicks are probably getting lost in the mix and end up sounding much weaker than ideal. So once you’ve added the side chain, things are going to sound a lot cleaner.

Step 1. Add a Fruity Limiter

First up, you’ll want to open up and add a Fruity Limiter to the track you want to ‘duck’ under your kick. For instance, in this case, we’ll be ducking the kick under the Bass Synth track.

Step 2. Link the kick to the bass signal

We’ve added the initial Fruity Limiter, now we have to link the kick track to the bass synth track. To do this, simply select the Kick track, then right-click on the small arrow on your bass synth track.

That will then open up a menu window, where you can select the “Sidechain to this track” option.

Step 3. Basic Settings

Ok, everything has been added and linked together. It’s now time to tweak your settings and make sure everything is sounding as good as it can. Depending on how you’re using Sidechain, the settings are always going to be different. But we’ve given you a basic run down to get started before you fine tweak it to suit your sound!

So open up your Fruity Limiter, and start by changing it from LIMIT to COMP mode.

Next, you’ll want to change the number in the SIDECHAIN box to 1. Then, drop the THRESHOLD amount, and increase the RATIO until its starting to sound the way you’d like it to.

You’ll notice the kick and bass signals are now working together, and your sound is going to sound so much cleaner. But what else can you do to make your sidechain in FL Studio sound even better? There are a number of settings in your Fruity Limiter that are going to affect the way your compression sounds, so it’s worth playing around and tweaking it until it sounds perfect.

Alternative Method – How to Sidechain in FL Studio using Automation

Alternatively, you can use the method of volume automation to perform a similar effect. Technically, this isn’t sidechaining, since the automation will control the volume of the signal you want to duck (in this case the bass) independent of the kick signal. Rather than being linked together using the Fruity Limiter.

This method is easy, but it can get a bit more tedious. However, it does allow for a lot more flexibility and control over your sound. In saying that, you’d only really use it over the Fruity Limiter technique if you were trying to create a specific sound effect that you couldn’t achieve otherwise.

For instance, you can choose between letting your effects such as your reverb and delay tail off while ducking the sound for an interesting effect. Or, apply the automation to your mixer track volume and completely silence the effects if you’d rather.

Step 1. Create a Fruity Balance Volume Automation Clip

First things first, you’ll want to head over to the mixer track you want to duck (In this case we’re ducking the Bass) and add an instance of Fruity Balance.

From there, we’ll want to link the volume knob to a separate automation clip. So right-click on the Fruity Balance volume knob, then select “Create Automation Clip” from the drop-down menu. You should now see a new automation clip appear in your playlist.

Step 2. Adjust the Automation Clip

Now what you’re going to want to do is shape the automation clip so we can achieve a similar ducking effect as the previous method. Essentially, we’ll be creating a hole in the frequency spectrum where the kick can fill in. So it’s important to take note where your kick drum starts, peaks, and ends. That will give you a good idea as to when to drop the volume of your bass synth and when to bring it back up again.

Step 3. Copy the automation

That’s basically it! Our automation has been created and you should be seeing (and hearing) a similar effect as you would using the Fruity Limiter. Now the only thing left to do is copy the automation pattern across your entire track where you want the effect to come into play. That’s unless you want to spend unnecessary amounts of time creating automation curves throughout your song.

Method Three – Gross Beat

Finally, the last and possibly the easiest option for side-chaining a specific pattern in FL Studio is done by using the Gross Beat plugin.

Step 1. Add an instance of Gross Beat to the mixer track you have your bass/lead synth/or other sound you want to duck

Sidechain FL Studio

Step 2. Head into the Gross Beat plugin and select the sidechain option from the left hand side (See below)

This will automatically add a subtle sidechain effect to your track. From there, you can adjust the automation clip to your liking if you wanted to make a different pattern or change the intensity of the sidechain.

The Final Say

That’s it, three simple methods on how to Sidechain in FL Studio. Gross Beat is the easiest method for a simple sidechain pattern, while the Fruity Limiter gives you more control over your compression. Then you have the automation method that although not technically sidechaining and can get a little tedious, gives you even more flexibility over your sound. Hopefully you learned a thing or two and can use these techniques to make your tracks sound even better!
