How To Sidechain In Bandlab

Sidechaining is a powerful mixing technique that adds punch and groove to your tracks. It involves dynamically adjusting the volume of one audio track (usually a bass or kick drum) in response to the rhythm of another (often a lead synth or vocal). This creates a pumping effect, making your mixes sound more dynamic and professional. This guide will walk you through how to achieve this effect in BandLab, step-by-step.

Understanding Sidechaining Fundamentals

Before we dive into the BandLab specifics, let's quickly cover the basics. Sidechaining relies on a compressor. This compressor doesn't simply reduce the overall volume; it reduces the volume only when the trigger audio (your kick or bass) is playing. When the trigger signal is quiet, the volume of the compressed track returns to its normal level. This creates that signature "pumping" effect.

Key Elements of Sidechaining:

  • Compressor: The workhorse of the effect. It dynamically reduces the gain of the target track.
  • Key Input (Trigger): The audio signal that controls the compressor. This is usually a kick drum or bassline.
  • Target Track: The audio signal whose volume is being controlled by the compressor. This might be a synth, lead vocal, or pad.
  • Ratio: This setting on the compressor determines how much gain reduction occurs. A higher ratio (e.g., 4:1 or higher) creates a more pronounced pumping effect.
  • Attack: This determines how quickly the compressor reacts to the trigger signal. A fast attack (e.g., 1-5ms) creates a tight, punchy sound.
  • Release: This determines how quickly the compressor returns to its normal level after the trigger signal stops. A slower release (e.g., 100-500ms) adds to the pumping effect.

Sidechaining in BandLab: A Step-by-Step Guide

BandLab doesn't have a dedicated sidechain function, but we can achieve the same effect using its built-in compressor and routing capabilities. Here's how:

1. Preparation:

  • Create Two Tracks: You need at least two tracks: one for your key input (the trigger) and one for your target track (the one to be compressed). Let's say your kick drum is on Track 1 and your lead synth is on Track 2.

2. Routing the Key Input:

  • Send the Kick to an Aux Track (Optional): For cleaner organization, create a new aux track. This keeps your main tracks organized and allows flexible adjustments later on. Send your kick drum (Track 1) to this aux track using BandLab's send feature. Adjust the send amount to your preference.

3. Applying the Compressor:

  • Add Compressor to Target Track: Select your target track (Track 2, the lead synth in this example). Add a compressor effect to this track. BandLab has a variety of built-in compressors. Experiment with different ones to find your favorite.

4. Sidechain Routing (The Key Step):

  • Set the Sidechain Input: This is the crucial step. Most compressors in BandLab allow you to select the input source. Instead of using the track's own signal, route the key input (either the Kick directly from Track 1 or from the Aux Track you created) to the compressor's sidechain. This is how you tell the compressor to listen to the kick drum and react to it. The exact way to do this varies slightly depending on the specific compressor used within BandLab. Look for an option to select the sidechain input source within the compressor's parameters.

5. Adjusting Compressor Parameters:

  • Fine-tune Your Settings: Now comes the creative part. You’ll need to experiment to find the right sound. Start with these settings as a base:
    • Ratio: 4:1 - 8:1 (higher ratios create more pronounced pumping)
    • Attack: 5-20ms (fast attack keeps the pumping tight)
    • Release: 100-500ms (slower release creates more of a pump)
    • Threshold: Adjust this to control how much gain reduction is applied. Start with a moderate setting and gradually decrease the threshold until you get the desired effect.

6. Listen and Adjust: Pay close attention to how the sidechain effect interacts with your overall mix. You might need to adjust the volume of your kick or synth tracks to achieve the balance you’re after.

Tips and Tricks for Mastering Sidechaining

  • Experiment with Different Compressors: BandLab offers different compressors. Experiment to find one that suits your taste.
  • Listen in Mono: Sidechain effects can sometimes sound different in mono compared to stereo. Ensure your mix sounds good in mono too.
  • Subtlety is Key: Excessive sidechaining can sound artificial. Strive for a subtle and tasteful effect that enhances your mix rather than dominating it.
  • EQ Your Trigger Signal: Consider EQing your kick drum or bassline to focus on the frequencies that will effectively trigger the compressor.

By carefully following these steps and experimenting with the compressor settings, you can effectively use sidechaining in BandLab to add depth, groove, and professional polish to your mixes. Remember, practice makes perfect! Don't be afraid to experiment to find the perfect sidechain settings for your tracks.
