Side chaining is an essential technique in music production, often used to create space in a mix and introduce rhythmic elements. If you've ever felt that your mix lacks punch or clarity, side chaining could be the solution. ProTools offers a straightforward way to implement this powerful tool, making it accessible for both beginners and seasoned pros. In this post, we’ll walk you through the side chaining process in ProTools, providing clear steps and examples to enhance your productions.
What is Side Chaining?
Side chaining involves using the audio from one track to control the level of another track. One of the best-known uses of side chaining is when a kick drum triggers a compressor on a bass line, creating a "pumping" effect. For instance, in many popular tracks, this technique allows the kick to be prominent while keeping the bass rhythmically in sync—it ducks the bass every time the kick hits.
Additionally, side chaining is not just for compression. Techniques can also be applied in gating, where the noise gate’s functionality is triggered by another signal, helping to manage unwanted sounds in a track. For example, you might use a snare drum track to control a gate over a noisy ambient track, ensuring the ambience only comes through in moments of silence.
Setting Up Side Chain in ProTools
Step 1: Create Your Tracks
Begin by creating at least two audio or MIDI tracks. For our example, let’s set up a kick drum track and a bass track. Make sure both tracks contain the audio content you want to use. For example, you might have a kick drum recorded at -6 dB and a bass line at -3 dB.
Step 2: Insert a Compressor on the Destination Track
On the bass track (the one you want to affect), insert a compressor from the plugins menu. While many compressors work well, ProTools’ built-in Avid Audio Compressor is an excellent choice for this task.
Step 3: Enable Side Chain on the Compressor
After inserting the compressor, look for the option to enable side chaining. In the Avid Audio Compressor, there's a "Side Chain" button. Click this to activate the side chain functionality.
Step 4: Select the Input Source
Next, configure the compressor to listen to the correct signal. In the compressor's control panel, you'll see an option to select the side chain input. Choose your kick drum track from the dropdown menu. This setup ensures that every time the kick drum plays, the compressor reacts accordingly.
Step 5: Adjust the Compressor Settings
With side chaining active, tweak the compressor settings to achieve the desired effect. Here are some recommended starting points:
Threshold: Set around -14 dB for a balanced response.
Ratio: A 4:1 ratio will give you a noticeable reduction.
Attack: Aim for a fast attack time of around 5 milliseconds.
Release: A quick release around 50 milliseconds will enhance the pumping effect.
Step 6: Experiment and Iterate
Don’t hesitate to play around with the settings. Side chaining is as much about feel as technical finesse. Listen closely to how the bass responds to the kick and adjust the compressor until you find the right balance.
Additional Applications of Side Chaining
Vocal Mixing
In vocal mixing, side chaining can help maintain clarity among multiple vocal tracks. When you have a lead vocal with backing vocals, apply a compressor to the backing vocal track with the lead vocal as the side chain input. This will ensure that the backing vocals smoothly duck in volume when the lead vocal is present, creating a more professional mix.
Creating Space in the Mix
Side chaining can help create more room in your mix. For instance, you could use side chaining to trigger effects like reverb or delay based on a vocal track. This approach prevents effects from overwhelming the mix, allowing elements to breathe and sound cleaner. A study showed that mixes using side chaining effectively had up to 30% improved clarity, enhancing listener experience.
Creative Effects
Beyond clear mixing, side chaining can serve as a method for creative sound design. By side chaining various effects, you can inject rhythmic elements into sections of your music—for example, creating a pulsing synth pad that ducks every time the kick hits.
Troubleshooting Common Issues
Side Chain Not Working
If you find that side chaining isn’t working, double-check the compressor settings. Make sure the compressor is set to receive the side chain signal and that your input source is selected.
Unwanted Artifacts
If you hear unintended artifacts like excessive pumping, this could be due to compressor settings. Slow down the attack or extend the release to create a more natural sound. Making these adjustments often resolves such issues.
Latency Issues
When using certain plugins for side chaining, you may experience latency issues. ProTools offers a Low Latency Monitoring mode, which helps reduce latency. However, keep an eye on overall mix quality, as this may impact your monitoring situation.
