Questions and Answers from the YouTube Video

Can I do this in Logic Pro X too?

For a vocoder effect in Logic, EVOC 20 is a good option. We have a tutorial as well, although it uses Logic 9: https://sleepfreaks-dtm.com/for-advance-logic/evoc20/

Apply the Vocoder

First, prepare your audio material. The video uses a vocal.

On the audio track you want to process, add Audio Effects → Vocoder.

Create a MIDI track separately from the audio track.
We used Instruments → Instrument Rack → Synth Lead → 10 Saws Lead.adg.

Program notes on the MIDI track.

Configure the Vocoder

• Carrier
  Change Noise to External.
• Audio From
  Change No Input to the MIDI instrument track (10 Saws Lead).
  Select Post FX.

Turn on Enhance to boost the high frequencies.

Try adjusting Formant and the other parameters
to create interesting effects.
Try using them in your own music.

Frequently Asked Questions

Q1. What are the basic settings for Ableton Live’s Vocoder?

Add Vocoder to an audio track, set Carrier to External, and select the MIDI instrument track under Audio From with Post FX. The instrument plays the programmed MIDI notes and supplies the carrier audio, giving the processed audio a pitched character.

Q2. What helps when creating a robot voice?

Align the notes programmed on the MIDI track with the vocal, and turn on Enhance to boost the high frequencies. Adjust Formant and other parameters to create a more natural or distinctive robotic sound.

Q3. How does a vocoder differ from ordinary pitch correction?

A vocoder mainly modulates an audio signal’s timbre using a carrier, such as a MIDI-controlled instrument, and is known for robotic effects. Pitch correction instead adjusts the pitch of an existing sound, so the two have different uses.
