Let me show you how to Side Chain in the Logic Evoc-20 Vocoder to reinforce the rhythm and pulse of your beat. There are two vocoders in Logic: the Evoc 20 Polysynth and the Evoc 20 Track Oscillator. Here's the plugin that you can insert on another synth track, the Evoc 20 Track Oscillator, and what I have muted for now is the Evoc Synthesizer.
This is the Evoc 20 Polysynth. They have a very similar interface. The distinction is that the Evoc 20 Polysynth has oscillators to generate sound and the Evoc 20 Track oscillator is an effects plugin that you can insert on a software instrument. You'll hear that they have a very similar sonic quality. Let's use the Evoc 20 Track Oscillator first, this one that I have inserted on the EXS24 String Pad, and let's have a listen to the results.
(music playing) I'll bypass the vocoder and add it back in. (music playing) So here's what I have set up. On audio track 1, I have this beat. Solo it by hitting the S key. (music playing) On the track with the vocoder are EXS24 Strings, I have the Side Chain set to track 1.
So when I play it back, you're listening to the chords chopped and rhythmically playing exactly the same rhythm as the drumbeat. (music playing) I have a few other beats loaded on Audio 1, but muted. I'll mute this Trip Hop beat and bring up another one. (music playing) Here's that beat by itself. (music playing) And now you can hear it triggering the same rhythm on our pad.
(music playing) Let's hear it going through one more beat. I'll mute this one and bring up this jungle beat. (music playing) So let's experiment a little bit with some of these settings inside the vocoder. We'll go back to a simpler-sounding beat. And the ones that are most dramatic are the Formant Shift, the Formant Stretch, and extending out this bar, you can watch the display here. Let's have a listen.
(music playing) And of course, all of this could be automated. (music playing) And that's it. What I have muted here is the Evoc Synthesizer, so let's mute the strings coming out of the EXS24, and hear the same effect coming out of the Evoc PS Polysynth.
(music playing) Same thing, play with the Formant Stretch. (music playing) Again, the difference here is that we're using synth sounds generated by the internal oscillators of this synthesizer. (music playing) I'll switch the beat that's triggering it in the Side Chain. (music playing) And that's how the Logic Vocoder reinforces the pulse of a beat for a dance track, pop song, or maybe a movie soundtrack.
