How to Autotune in Logic

By Edited May 26, 2015 0 0

Logic Pro is a very powerful DAW that comes with an excellent library of plugins and presets. One such plugin is the pitch corrector, or auto tune.

In this tutorial, however we're going to look at how to autotune in Logic as an effect. The sound is similar to a vocoder, in that it makes your vocals have a robotic sound to them, but it carries the original melody that is sung.

This is a very popular effect in today's pop songs. Often times, vocal tracks are autotuned by making subtle, slight corrections to the pitch. This is done by making small changes to the speed at which the recording is played. In most situations, you would never hear it in the mix. This is because the corrections start shortly after the note is sung. However, if we set the pitch correction to respond immediately, the effect will be much more apparent. Let's get started.

  1. Open up Logic Pro and open a project with a vocal track, or create a new project and record a vocal track. The melody should be sung as normal.
  2. In a channel strip, add an insert. Choose Pitch -> Pitch Correction.
  3. Choose the key of the song.  This will tell the pitch correction plugin which notes are in key. In my case, the song is in C major. If there's a particular note you want to disable, you can do so by clicking the 'byp' button.
  4. Setting the response to 0.00
    Turn Response all the way down to 0.00. This controls the tracking speed, or how quickly pitch correction occurs. At this rate, it will make things sound very robotic.
  5. If the effect isn't strong enough, try putting a flanger before the pitch correction plugin. You'll need to experiment with the settings, but a flanger can slightly detune your voice. The pitch corrector will then adjust it back up to be correct. Here are some settings that I thought sounded pretty good.

Tip: I'd recommend against recording with pitch correction on. You will have a hard time monitoring yourself and singing properly. The result will be a wildly out-of-tune track.
