Anyone who has tried to record a song singing will have realized that getting a perfect tuning is extremely difficult if we do not have great talent. In fact, we will be lucky if we only manage to hit the notes we want to sing. So how do singers make their voice sound so in tune on records and when we hear them live many times that level of the pitch leaves a lot to be desired? They usually have a great producer or technician behind them. As you may have already imagined, in most cases, some processor is used to help us place the height of the notes in their place. The most famous processors are perhaps Autotune, Melodyne, Waves Tune,
If the software you use is Ableton Live, and your goal is not to tune, but to change the pitch of an audio file, take a look at this post. However, today we are going to show you how to tune vocals in Logic Pro without any of these plugins that you have to buy apart from our DAW. Only with Logic Pro’s Pitch Correction tuner will we be able to tune our voices both gently, so that it practically goes unnoticed, and in a more drastic and brazen way, to achieve a robotic voice effect type T Pain or Cher.
How to use Pitch Correction to tune vocals in Logic Pro
First of all, we will have to configure the Pitch Correction processor in one of the boxes dedicated to the inserts of the track. Now let’s see what considerations we must take into account to properly configure its parameters.
First of all, we must configure in the Range area if we are going to use the processor with a more or less high-pitched sound (voice), such as a female voice, represented by the “Normal” tab and a key symbol. Sol. Or on the contrary, if we are going to use it with a more serious sound, such as a male voice, we will configure it in «Low«, with the symbol of the bass clef. Perhaps there are voices, both males that sings quite high, and female that sing quite low, that is in an intermediate range, therefore it would be convenient to try both logarithms and see which one offers the best result.
Once we have configured the type of voice that we are going to process, the next step is to indicate to the processor the scale (or tonality) on which we are singing. For those of you who are not very familiar with scales, I recommend that you take a look at the entry The musical scale: source of harmony and melody. When selecting the scale on which we are interpreting, let’s say that we will deactivate the 5 (of 12) notes that do not correspond to that scale, and, when in doubt, the processor will always opt for a note that, in principle, should sound in accordance with the scale. song. We will have to select both the tone (root note of the scale), and the mode (major, minor, etc…) We also have the possibility of doing this process of canceling the option that certain notes sound manual, using the bypass option of the different notes that appear on the keyboard.
Now we know that the processor is going to recognize the appropriate notes, we only need to indicate how (with what speed) it is going to correct the pitch of the voice. If we configure a slow time in the Response parameter (high value in milliseconds) we will make this correction barely distinguishable, making the beginning of the sound may have some imperfection in the pitch, making it more natural, but it WILL tune the body and the tail of the note. If, on the other hand, we configure a fast time (small value in milliseconds) we will make the note jumps more abrupt, being able to create a kind of robotic effect, which can sometimes be part of artistic creation, being something original.
The last option we find is Detune, which will allow us to modify the tuning of the entire signal that passes through the processor, having the option of creating double voices or simply modifying the tuning as a creative resource.
As you have seen, tuning voices in Logic Pro is a relatively simple task and allows us to solve technical problems (bad tuning) to create an effect (“robotic voice” at a given moment). From now on you have no excuses for your projects to sound perfectly in tune.
