Logic Pro X: Sends, Buss & Aux (Beginners guide)

Introduction

This tutorial will guide you through the essential concepts of Sends, Busses, and Aux channels in Logic Pro X. Understanding these features is crucial for achieving a professional sound in your music productions. By the end of this guide, you will know how to effectively use these tools to enhance your audio mixing.

Step 1: Understanding Sends

Sends allow you to route audio signals from a track to an auxiliary channel. This is useful for applying effects to multiple tracks simultaneously without affecting the original signal.

How to Use Sends

• Create an Aux Channel:

  • Go to the Mixer view (press 'X').
  • Click on the "+" button at the top of the mixer to create a new Aux channel.

• Set Up the Send:

  • On the track you want to send from, locate the “Sends” section.
  • Click on an empty send slot and select the newly created Aux channel.

• Adjust Send Level:

  • Use the fader on the send to control how much of the signal is sent to the Aux channel.

Practical Tip

Use sends for effects like reverb or delay, allowing multiple tracks to share the same effect without duplicating processing power.

Step 2: Exploring Busses

Busses are similar to sends but are primarily used for routing audio signals to a mix bus for processing.

How to Use Busses

• Create a Bus:

  • In the Mixer, click on the “Output” section of the track.
  • Choose a bus (e.g., Bus 1) from the dropdown menu.

• Route Tracks to the Bus:

  • Any track assigned to this bus will send its audio signal to it, allowing you to process these tracks collectively.

• Apply Effects on the Bus:

  • Insert effects directly on the bus channel to manipulate the sound of all routed tracks simultaneously.

Common Pitfall

Avoid sending too many tracks to a single bus, as this can lead to a cluttered mix. Balance the number of tracks and adjust levels accordingly.

Step 3: Utilizing Aux Channels

Aux channels are used for routing effects and can be utilized in conjunction with sends and busses.

How to Use Aux Channels

• Add Effects to an Aux Channel:

  • Open the Mixer and select the Aux channel you created earlier.
  • Insert your desired effects (e.g., EQ, compression) directly onto this channel.

• Control Wet and Dry Mix:

  • Adjust the balance of the effects by controlling the wet (processed) and dry (unprocessed) signals.

Real-World Application

Create a dedicated Aux channel for vocal reverb. This allows you to easily control the reverb level for all vocals without affecting other tracks.

Step 4: Practical Workflow Tips

• Label Each Channel: Keep your mixer organized by labeling each Aux and Bus clearly (e.g., “Vocal Reverb”, “Drum Bus”).

• Use Color Coding: Color code tracks and channels to visually distinguish between different types of audio.

• Experiment with Different Effects: Don’t hesitate to try various effects on your Aux channels to discover new sounds.

Conclusion

In this tutorial, you learned about Sends, Busses, and Aux channels in Logic Pro X, and how they can enhance your mixing process. By effectively using these tools, you can achieve a more polished and professional sound in your productions. As a next step, practice applying these techniques in your current projects to see how they can elevate your music.
