Why Using Sends for FX is a Game-Changer in Vocal Mixing

When it comes to vocal processing in electronic music production, one of the most overlooked yet powerful techniques is using send effects rather than applying effects directly to the vocal track. If you're looking to achieve a cleaner, more professional mix while maintaining full control over your reverbs, delays, and other spatial effects, using sends for FX is a must.

In this article, we’ll break down why using sends can transform your vocal mix, how to set them up properly, and why top producers rely on this method to keep their tracks polished and dynamic.

What Are Sends in Music Production?

In DAWs like Ableton Live, FL Studio, Logic Pro, and Pro Tools, "sends" (or auxiliary sends) allow you to route a portion of your track’s signal to an effect bus, instead of applying the effect directly to the track. This means that your dry signal remains intact while an affected version is processed separately.

For example, instead of slapping a reverb plugin directly onto your lead vocal, you send part of the vocal’s signal to a separate reverb track (also called a return track or FX bus). You then blend this affected signal back into the mix.

This technique is widely used in professional mixing because it provides more control over your FX levels while preventing unwanted muddiness.

Why You Should Keep Your Reverbs on Sends

1. Cleaner Mixes & More Clarity

One of the biggest challenges in vocal mixing is maintaining clarity while adding depth. When you apply reverb directly to a vocal, it can muddy up the mix, making the vocal less distinct.

By keeping your reverb on a send, you can:
✔️ Control the exact amount of wet vs. dry signal.
✔️ EQ the reverb separately to remove unnecessary low-end frequencies.
✔️ Use sidechain compression to reduce reverb levels when the vocal is active.

2. More Control Over Your Effects

When your FX are placed on separate send channels, you gain total control over them. You can:
✔️ Automate the reverb send for different sections of the song.
✔️ Adjust decay times and fine-tune reverb tails independently.
✔️ Add compression, saturation, or modulation to the FX track without affecting the dry vocal.

This level of precision is key in professional mixing and makes a massive difference in how polished your vocals sound.

3. CPU Efficiency & Lighter Projects

Instead of placing multiple reverb plugins on different tracks, you can create a single send track for reverb and route multiple tracks to it.

This:
✔️ Reduces CPU usage by processing the effect only once.
✔️ Keeps your DAW session more organized.
✔️ Avoids unnecessary duplicate reverb processing, which can clutter the mix.

4. Creating a Cohesive Soundstage

By sending multiple elements (vocals, synths, drums) to the same reverb send, you create a unified space within your mix. This technique is often used in Deep House, Melodic Techno, and Chill Dance Music to give the track a sense of depth and ambiance without overwhelming the main elements.

How to Set Up Sends for Vocal Reverb (Step-by-Step Guide)

If you're new to using sends, here’s a quick and easy way to set up a reverb send for your vocals in most DAWs:

Step 1: Create a New FX Send Track

  • In your DAW, create a return/auxiliary track and name it Reverb Send.
  • Load your favorite reverb plugin onto this track.
  • Set the reverb plugin’s mix to 100% wet (since we’ll control the blend using the send knob).

Step 2: Send Your Vocal Track to the Reverb Send

  • On your vocal track, find the send knob and increase it to taste.
  • Start with a moderate send level (-15dB to -10dB) and tweak as needed.

Step 3: EQ Your Reverb

  • Insert an EQ plugin after the reverb to clean it up.
  • Cut low frequencies (below 250Hz) to avoid muddiness.
  • Reduce harsh highs if needed (above 8kHz).

Step 4: Add Sidechain Compression (Optional, But Powerful)

  • Insert a compressor on the reverb send.
  • Sidechain it to the dry vocal, so the reverb ducks slightly when the vocal is present.
  • This ensures the reverb doesn’t overpower the main vocal.

Step 5: Adjust the Blend & Automation

  • Fine-tune the reverb send level for each part of the song.
  • Automate the send amount if you want more reverb on certain words or phrases.

Other Effects You Should Always Use Sends For

Besides reverb, here are some other FX that should be placed on sends:

1. Delay

  • Using sends for delay allows you to EQ and filter the repeats separately.
  • You can add reverb to the delayed signal for a lush, atmospheric sound.

2. Chorus & Modulation FX

  • Instead of drowning your vocal in chorus, blend it in subtly with a send.
  • This works great for dreamy, ethereal vocal processing in Melodic House.

3. Parallel Compression

  • A powerful way to thicken vocals while retaining dynamics.
  • Duplicate your vocal track to a compression send, smash it with heavy compression, and blend it back in.

Final Thoughts: Why Sends Are Essential in Modern Vocal Mixing

If you want your vocals to sound clean, professional, and dynamic, using sends for your FX is a game-changer. Instead of cluttering your mix with multiple reverb and delay instances, sending FX to separate tracks allows you to maintain clarity while crafting a lush, atmospheric sound.

Whether you're mixing deep house vocals, airy melodic techno toplines, or intimate indie dance vocals, this technique is key to achieving a polished, emotional mix.

So next time you're mixing, ditch the direct FX and embrace sends—your mix will thank you.
