An Introduction to Saturation

Hi there and welcome to this section where I'm going to explore Chromo Globe. This is a saturation and distortion plug in and this effect is based on hardware units. So saturation can be great for adding saturation or distortion onto different instruments or vocals. You can even use it for mastering where you apply it to your master bus. This can help give your songs a bit more kit or grit and adds character to your music. Before we get started looking at this effect, let's talk about what saturation is. Saturation is a type of distortion. And this is really what makes analog hardware sound pleasing. We can also emulate this with digital plugins like Chromo Glow saturation can give your music analog warmth and can make the sound fuller by adding harmonic frequencies. Let's now talk about what adding harmonic frequencies means. The best way to explain this is we have a test oscillator. So in logic pro we can add this by going to the effect slot and go down to utilities and test oscillat...

or. We can add this onto a midi or audio track. It won't make a difference. Let's now add a test oscillator in logic pro for ipad. So let's add a new instrument with this plus button up here. And now let's press the three dots next to Midi software instruments and where it says patch slash instrument, let's change the default patch to test oscillator. So we can do this by going down to utility and then choosing test oscillator and then hit create. Let's just turn this off for now as the sound can get a bit annoying. Let's also make sure this is set to a sine wave and let's put the frequency down to 250 Hertz. Now, when we turn this on you here, it's a little less annoying, but let's turn this off for. Now, let's now actually close the browser and also the play surface area as this has taken up a lot of unnecessary space. OK? Now let's add a channel EQ. So let's go over to the mixer and then change this to setup mode up here. Now, in the test oscillator instrument, let's add an EQ and we can do this by clicking on the audio effects here. So let's go to EQ and now let's go to channel EQ. Now let's tap on this and go and show details. So now when I turn on the test oscillator, you can see it will give us a frequency at 250 Hertz. So let's tap on test oscillator here and then tap turn on. Let's just tap on this again and press bypass so we can't hear this anymore. OK. So now we're going to add the chrome glow plug in and we're going to have this before the channel EQ. So let's just scroll down in the mixer here and tap on this plus button to add a new plug in. So we can find the chromoly effect by going to distortion and then crime we lie. However, as I said, I do want to have this before the channel EQ. So let's just tap and drag this down. So now the test oscillator will go to the chromoly effect and then we can see what the frequencies will look like in the channel EQ. So let's turn on the test oscillator again and let's show the details for the channel EQ right now, it looks the same, but let's actually increase the drive dial on the chromoly effect. Now you can see if we go back to the EQ, there are more frequencies. So the Chromo Glow saturation effect is creating harmonics from this one frequency produced by the test oscillator. This is why adding saturation makes the sound fuller and richer as it adds more frequencies. So let's now tap on Chromo Glow and go to show details. Also in Chromo Glow, we have different saturation models, these will boost certain harmonics more than others. So let's just quickly choose another model. We can do this by clicking on this drop down here. And for this example, let's choose magnetic. Now, I'm going to play this back and open up the channel EQ and then swap between the different models on the chromoly effect. So you can see that the different models will boost certain harmonics one of us. So let's do this now. OK. So let's turn off the test oscillator now. OK. So I just wanted to demonstrate that with a test oscillator. So we can clearly see the difference. However, we're not going to use the test oscillator anymore. So let's actually delete this track. So we can do this by tapping on the track here and then go to delete that says you're going to delete objects that are assigned to tracks and the tracks area. But I'm going to select delete anyway, as we're not going to use this, let's now close a mixer by tapping on this button and let's also tap on the plug in button here as we don't need to display this. Now, let's also delete this track here in the tracks area by tapping on this and then going to delete. OK. I just wanted to organize our project before we continue. Let's now continue talking about saturation. So you can add saturation to anything in the mix that needs to sound a bit thicker. It can often be used on bass, electric pianos, drums or even vocals, for example. But remember it's not needed on every individual track in the mix. It's also nice to add saturation to the master channel, which can give your song a bit of warmth and can make it sound a bit thicker. So adding saturation can help tracks or instruments cut through the mix better and can give fullness and attitude to certain parts from the harmonics. It adds, but remember not to overdo it with this effect and keep it subtle. OK. So that's what saturation is in the next video. We'll explore some presets in Chromo Glow. So thanks for watching and I'll see you there.
