Join Joe Godfrey for an in-depth discussion in this video Using loops to build a groove, part of Logic Pro 8 Essential Training.
Having all these loops is great, and having the ability to search and audition is all great, but what good is it really until we can make music with them? So that's what we are doing now. So I am going to go to My Favorites and I have already selected these four. If you need to know how those got there, watch the previous movie. The green icon means that Shakuhachi contains MIDI data and if I dragged it to the big gray window, Logic would automatically build a MIDI track to hold it. Let me show you a little trick. If I drag this MIDI loop to an audio track, Logic automatically converts it to an audio file in this key and this tempo.
In an audio sequencer, we prefer the flexibility of MIDI but converting MIDI to audio is handy if you want to use this sound in a program that doesn't accept MIDI files like Final Cut or Motion. Next step, I will add my drums. Just dragging them to the timeline, Logic creates the audio track that it needs to play the sound. Next up is my fretless bass. Now, I was a little inaccurate on purpose when I dragged this to the timeline and dropped it on bar 2. I am actually going to move it now to bar 1 because I wanted to start at the beginning and I will drag my guitar and insert it at bar 1.
Now, it's muted my drums. I'm going to take the mute off my drums and let's hear what this sounds like. (Music plays.) Well, I think maybe that Shakuhachi should be out on its own. So for now, in this music creation process, I don't need access to these loops anymore. I am going to push this out of the way and just have a nice big Arrange window to work with. I have selected 95 beats a minute here. I kind of like this tempo just to experiment.
Let me try 105 beats a minute and see what it's like at that tempo. (Music plays.) Well, that's too fast. Let's try 90 and see what it's like at that tempo. (Music plays.) I actually kind of prefer 95. Now that I have tried both sides of it. I guess we could call that bracketing the tempo. Try that one that's a little faster. Try that one that's a little slower. That will help you decide what's the right tempo for the piece you are writing.
So back the beginning. I am going to push the drums back to bar 3, actually all of these little pieces back to bar 3. I may want the fretless bass to come in before the drums but my goal here is to isolate this Shakuhachi at the beginning for now. (Music plays.) I think I am happy with that. I may change my mind later. That's the beauty of Logic is you start assembling things and nothing is glued down.
You can pick it up and move it. So to make these regions loop, I go to the upper right-hand corner of this region, push and drag out. Let's make this piece be 16 full bars long and I will just push and drag all of them out to 16 bars long. Except the Shakuhachi. Now, I think I am done with the left side of this. I don't think I need to do any inspecting of any of these tracks right now. I will push this bar over to the left and now I have a nice big Arrange window to work with. If I hit the 0 key, I have sized the Arrange window to the entire length of my piece.
If you want to resize the tracks vertically, hold down the Ctrl key, hit the Down arrow until the tracks are the size that you want them, so that's looking pretty good to me now. I am going to play it again. (Music plays.) Now I am hearing just a little bit of distorted crispness in my headphones.
I am going to push this out just a little bit and bring my overall volume down, just a smidgen, maybe 5 db. That's going to depend on what output you are using whether you need to adjust this up or down. Now, I will push this back out to the left and listen some more, right from here, from bar 6. (Music plays.) All right, I actually do want to change the level of the drums against the bass and the guitar. So to do that, there are several ways to do it.
I am just going to pop out to the Inspector for that track and for Audio 2, I'll bring its volume down just a little bit. It's a very intense loop you could see it has really spiky waveforms here that are right up to the top. So, it's not clipping my track but it's louder than I want it to be and that's where I adjust its relative volume from the drums to the bass to the guitar. There is the relative volume of the drums. There is the bass. There is the guitar. Now, I will rename my track to Shaku so I know what sound is in this track, and this one we call groove.
These are already called Fretless Electric Bass and Muted Electric Guitar. They take their names from the MIDI loops. So now, I have got it sounding about like I want it to sound. I will push this left wall out again and now I have a nice big Arrange window to work with. So, here is my idea. I am going to put the playhead back at the beginning and explain my idea and then do my idea. I would like the bass part not to play the same thing over and over and over. I could double-click it and change the notes in the bass part manually.
It starts at bar 3. Let's say I want maybe one bar of the phrase and then.... (Music plays.) From bar 4 to bar 5, I wanted to do something different. I could delete the parts in this track and then replace them with a MIDI keyboard. That's one way of doing it. Here is another way of doing it. Let me close out the Piano Roll for that track. Just click on the word Piano Roll down here at the footer of the Arrange window. And instead of having this be loops all the way from beginning to end, I am going to take this one-bar phrase, hold down the Option key, drag it over here, drag it over here and now I have a phrase, some space, a phrase, some space, a phrase, some space.
So, that accomplishes part of the task of building this song out of loops. In the next movie, we will actually edit the MIDI data and finish the process.
