An arpeggiated chord refers to a separation of chords that are not played at the same time. The Arpeggiator in Logic Pro X is a MIDI effect plugin that allows you to create patterns in an arpeggiation or with an arpeggiated chord. The Arpeggiator allows you to change a group of notes that are set as a chord into a balanced arpeggio of notes. This online video explains how to use the Arpeggiator to build arpeggio sequences and patterns.
If audition a lot of patches you will come across some that have some information in green in the midi FX part of the channel strip. I'm talking about right here where it says midi FX. In this movie I will explore one cool midi effect, the arpeggiator. Midi FX looking and act kind of like audio effect plugin processing below them in blue. But actually no audio passes through them. They strictly alter and augment any incoming midi messages. While earlier versions of Logic had the capacity to do this, Logic pro 10 is the first time we see midi effects used as real time inserts directly in a track.
And it's a big payoff. One of the cool new MIDI effects to explore is the arpeggiator. Arpeggiators go back to the beginnings of electronic music, and basically. They provide a way to alter a group of notes held as a chord into a rhythmic, sequenced arpeggio of notes. Let's make a new software instrument track and load the soft square lead patch. Now to the bottom here and make a new track. And we'll do software instrument, open library and we'll just go to synthesizer here, and we're going to choose under lead, we're going to choose soft square lead.
Close the library. And on the soft square lead track, this is loaded up with a patch. And the patch doesn't include anything yet in the MIDI Effects. But let's open the Smart Control for soft square lead and type b in our keyboard to enable the Smart Controls. You'll notice in the smart controls, I don't know if you've noticed this before, but in the top right, a little button with a group of what kind of looks like a mountain of MIDI notes. And if I hover over it, it tells me That's the arpeggiator. So, I'm going to click on that.
And the second I click on that, look what happened in our track inspector. The arpeggiator was automatically loaded into the MIDI effects. So there's our arpeggiator. Before I even open the arpeggiator, let's just check out how cool it is. So, to hear the arpeggiator, I'm going to play a chord on my MIDI keyboard. (MUSIC) So I'm just holding down C, E, and G, a classic three note C chord. But notice what happens, it starts arpeggiating out in sequence.
(MUSIC) And if I play the song. (MUSIC) it's in rhythm. And if I add another note. (MUSIC) And another note. (MUSIC) Playing all of those notes out in a sequenced arpeggiation. So that, in a nutshell, is the power of the arpeggiator. But let's look in the actual midi effects to check it out. This is the arpeggiator tool here.
And there's some nuances that we'll go over how to alter it. So right now we're in what we call live mode which means, as logic plays, whatever group of notes we hold down as we just did, our arpeggiator out. We can change a few things about the way this goes down. First of all, we have latch mode up here. I turn that on, now I hit the chord (SOUND) and I don't have to keep my hand on the keyboard so it's just (SOUND). Forever latching out, that C chord (SOUND). going to actually turn down the instrument a little bit, so.
Still kind of hear it, but I want to be able to talk over it a little better. Even though we're in latch mode, I could go over and change the chord and it'll still latch out the next chord. Did like an A minor. (SOUND) G, back to C. The next thing we can do here is alter the timing. Notice it's tapping out at a rate of sixteenth notes. I can go in here and change it to say, eighth notes.
Dotted eighth notes. (SOUND). Even 32nd notes. It's kind of a cool sound. Let's go back to 16. You can also change the knob and do the same thing that way with a knob instead of going to the menu. The next area is the way the notes are ordered. If you notice. When I started the chord it goes upwards. So it goes from C to E to G. I can change this to go downwards, so it's going G, E, C. I can also make it go down and then up.
(SOUND) This one here acts when you add another note on. (SOUND) More interesting pattern when I added a couple of notes to an already made chord. Now we go back to the regular C chord and you'll hear how it's a little bit different. (SOUND) And this one here is my favourite. It's the randomizer. So when I click on this one, it's going to tap out the chords in a random sequence. (SOUND) Constantly changing. In fact, you can alter the variation with this variation control if you don't like what you're currently getting.
If you like one of these you can click the hand and it automatically will stay in that pattern. (SOUND) And you can go back to random. (SOUND) We can also change the octave range, which is a cool thing to do. It'll actually move up and down using these same notes. And check this out. (SOUND) Throwing in other octaves. (SOUND) Up to four octaves. (SOUND) Very cool. So now I'm going to click the Play button to stop the playback. So that's Live mode.
Basically you can turn on Latch or not, play a chord and you have all these different patterns, all these different rates at your disposal. Now I just want to quickly go into grid mode and we can see how that works. Now in grid mode there actually some pre sets in here that are pretty cool and basically makes the arpeggiator more like a sequencer. If you remember the ultra beat movie we had a sequencer going on and we sort of had a grid where we can tap out. Or draw in different notes, according to, in this case, a 16th note grid. But let's just look at some of the customized grid patterns first.
So, for example, let's check out Grooving Pulse 2. You can see it actually adds in a four beat grid. But there are varying velocities. The height of the actual column is the velocity. And let's see what this sounds like. (SOUND) See the interesting thing about a grid is once we start playing back, especially if you have an odd numbered grid, if you have like 5 beats but then our song is in 4 4 time. It'll start to repeat out in different interesting patterns over the course of the song.
So let's actually keep it in this create a movie octave range down a little bit and I want to play it along with the song and see what we get. (MUSIC) So this is interesting because again it has five beats so it doesn't always repeat on the exact same spot within each musical bar.
And then you notice when I started playing I had to, once again, hit a chord, and it automatically latched. But if follows this grid and it follows these velocity patterns, too. So this movie has provided a window into the arpeggiator tool. This is an awesome way to reference some old school techniques via the new midi effects plugins in Logic Pro ten. And you can add some rhythmic substance to your song. In the following movie we'll explore another midi effect, the Cord Trigger.
