So we're adding a bass to the track that we created in the previous movie with the guitar and a drum loop. Well, I've decided that I want to use one of these virtual instruments to add my bass part. I could plug-in a bass and record some audio, but I want to use one of these virtual instruments that are really cool that ship with Logic. So I'm going to try this Liverpool Bass. That's a pretty intriguing title and I'm using a MIDI keyboard to play this instrument. (Music playing.) So I'm in tune.
I'm in the right key. So I want to start this bass part right where the drums start and I'm going to give myself kind of run up to it. So I'm going to move my guitar part and my drums back two bars so that I can hear a little countoff to get ready for the part and then I'll put Logic into record. So here are my two bars and then I can start. (Music playing.) Well, the problem with that is it's technically correct.
I do have a click back here that I can listen to. The problem with it is it's not getting in the groove to play this part right off the get-go. Now when you put Logic into Record, you're going to get a click. If you want to hear the click during playback, there are some options for that. The Click options are down here on the right-hand corner. You can just turn on your Click. Typically, you don't want click during playback. So I wouldn't hear it if I hit the Spacebar and Play, but I will hear it if I hit the Asterisk key and Record.
But the problem is that click is not getting me launched into the groove to play this bass part. So one of my favorite things to do is to use drums for the count off. I'm just going to reach up to the drum part and push this loop so that it starts at bar 1. Later on I will worry about turning it back so that it actually matches the guitar. Now it's little short, so I need to extend it a little bit. No problem. Extend the loop little bit and now this drum part is the right groove to get me into the bass part. So this track is ready to record.
I'm going to hit the asterisk key. It's going to give me a little count off into the drum part, launch me into the right groove, so I can play my bass part. (Music playing.) Now there are a couple of different ways to get to perfection.
I could lay down another tape, but I like things about this one and I think I can edit the things I don't like about this one. But I'm just going to go ahead and edit this one. So I'm going to light up this region, scroll down to Piano Roll and I can edit this inside the Piano Roll. There are all the notes in my bass part, but I actually want I think to go to the Window and have the Piano Roll be its own separate window, because from here on out in this movie we're going to concentrate on editing. We don't need to see the Arrange window.
I pull up Piano Roll and then I'll maximize Piano Roll so that that's all we're seeing on this window. Now my Transport is still on effect. So if I hit zero, I go back to the beginning and if I use my Control+Left Arrow, I zoom in and see a little bit more of it. So there is my whole bass part. If you've never seen a Piano Roll before, over here are the keys. (Music playing.) So this is the pitch of a particular note and then this is where they occur on the Timeline.
So you're basically just-- if I just move this out of the way a minute-- you're taking a peek inside this region, you're looking at the data that's in there, but you're looking at in a real zoomed in kind of way. All right, so what's in here? I will Control+Right Arrow a little bit and let's just take a look at the notes as it plays. (Music playing.) The different colors are different MIDI velocities.
There is a tool for adjusting that. If you slide up here to the upper right -hand corner, change your arrow to the Velocity tool and let's zoom in just a little bit more here. I can take a particular note and click on it and change its velocity, not its pitch, but its MIDI velocity. And if I stop talking, you'll hear that the different velocities give different sounds of this particular instrument. (Music playing.) And there is a really interesting effect on this particular patch when I push the Velocity all over to the top.
(Music playing.) It has a little drop off of pitch there. (Music playing.) So I have to go all the way to 127 to get that. It starts about 124, 125. So on a particular note, I may want to have a little slide. Well, that's ideal for the last note of the piece. Let's scoot on out here and have this particular note play that little drop-off.
So let me start just a little bit before that. (Music playing.) Actually, on retrospect I don't like the drop-off. I need it to be a nice big long note. So I'll leave that one there. But there is probably another place in here in my song that would benefit from that drop-off. Maybe the very first note. Let's try that at bar 3.
(Music playing.) This note would benefit from the drop-off. (Music playing.) I even like it better there than I like it on the first note. It's too busy on the first note. (Music playing.) So, we'll leave that there. So that's a way to adjust all your MIDI velocities. Every single note has a range of colors here that it can trigger velocities.
So I'll go back to my Pointer tool. The other problem with this track besides the kind of irregular MIDI velocities is that some of these notes are a little bit behind the beat. Some of these I don't think I rushed really, but I dragged a little bit. So I'm going to select all the notes with Command+A and then if I slide up to this menu, I have a bunch of choices for how I want to quantize them and that means where they fall in relation to the beat. If I played them a little late, I can fix them.
So this is 16-note groove. It's regular notes, chi-chi-chi-chi chi-chi, as opposed to a swing. Chi-cha, chi-cha, chi-cha. So I'm going to quantize them to the 16th note and I see that they jump around a little bit. Let me undo that and then redo it and you'll see that they kind of snap to a grid. Now let's listen to another part. (Music playing.) Now sometimes when it quantizes, it pushes notes that I've meant to play separately together and that's the case where that happened.
So this note actually needs to come back just a little bit. Oops! I had all the notes selected. Let me select this note and move him back just a little bit. He needs to come between that note and that note and now he does. So that's the kind of editing you do in this Piano Roll. Now if quantizing makes it just a little too perfect for you, there is a really cool option in Logic. Let me just scroll up to Window > Transform. In Transform, I'm going to select all the notes inside bar 1 to bar 30 and apply a humanization to them.
This just applies some random amounts that you Select and Operate. So let's take a listen now and see what adding just to touch of random did to our piece. (Music playing.) Okay, so I sort of like the feeling that the touch of randomness gives to this bass part. It makes it feel a little more, well, human. Let me close out of Humanize.
I found a note here that's a little bit too long, so I'm going to zoom in with my Control+Right Arrow and I just pick up the end of this note and move it over and make it be the right length. So you can edit the duration of any length. You can make it longer, drag it out, make it shorter, push it in, and make it be just the right length. Now I want to take a quick listen to my bass part. (Music playing.) I kind of like what Humanize did to this.
So quantizing it to get it perfect, humanizing it just to add a touch of random. So we're done with Piano Roll. We've edited the bass part. We're back to the Arrange window. Let's take the Piano Roll out of the Arrange window and it's time to set up a queue and add some vocal.
