Rather than choosing different tools for interacting with audio regions from a tool panel, GarageBand's main cursor has many of its tools built in and become active depending on where you hover your mouse. So let's actually get an audio loop in here, so we can show this example, okay. Clicking on Loops in the lower right, I am going to click on Drums, and we will find a drumbeat here. Let's try--hear sample of couple of these funk beats. Actually, I am going to slow their tempo down a bit too, because we are still up at 157. So I will go down to around where they were created at.
(music playing) This one will be a good example. So I am going to drag it in to a new track. I am going to put at bar two. You may have noticed I have been doing that throughout the course, starting things at bar two. I like to always leave at least one bar, if not more, space before any given song begins, in case you want to actually have a little time before something begins. And we'll get into doing a count-in and setting the metronome and stuff. I will show you why that can be valuable later. But for now, that's why I continue to drag things into bar two.
This loop break here, it's an audio region. It's on a real instrument track. I am going to use this slider in the lower left here to zoom in just a little bit, so you have a little more view on our file here. Vintage Funk Kit 04 is a stereo audio file. I can tell that because I can see both left and the right waveforms. And by hovering my mouse in the center of the audio region, or anywhere in the heart of this colored bar, I can actually click with the standard cursor to select, click out to deselect. That's the way that you can actually interact with the region itself. You can even click and drag left or right to reposition it in time, have it, say, for instance, play later in the song or earlier in the song.
If I hover over the lower-left corner, my cursor becomes a trim tool. It allows me to click and drag the head of the region to the right, eliminating some of the audio material at the beginning of the region. Let's listen to that Trim edit. (music playing) Okay. I'm going to hit Home to go back to the beginning and for the moment I am going to turn off the metronome as well, because we don't need to hear that for this example. And keep in mind that you can only trim back out again as far as you had original audio material, so there is no way that I can trim past the start point of what this loop originally was.
So the trim tool is kind of about taking away from one of the directions, from either the head of the region or the tail of the region. So the lower right-hand corner, my cursor becomes a trim tool as well and allows me to take out a portion of my audio region. So now I just have the first four beats of this loop. (music playing) And finally, by positioning the mouse over the top-right corner of any given audio region, the cursor becomes a loop tool. This allows you to click and drag to the right, effectively looping the audio region as many times as you'd like.
(music playing) Okay. I'll press Undo and Home to go back to the beginning. Now that we have a four-beat loop, which was originally and eight-beat loop, let me make this six beats by trimming the end and then looping, and you will notice that what I've looped, as I press play here, is the six beats. (music playing) And you kind of hear that skip.
Basically, we have this bizarre 6/4 loop going on right now that really kind of isn't well suited for this type of beat. I mean you could argue that it's fine, but to me it sounds strange. So the point I would like to make about looping at six beats is if you actually want to modify the trim of an audio region that's already looped, as you click and drag to retrim the region, you'll notice that all of your loop instances adjust to accommodate. So I have brought this down to now be only two beats long, and my entire original audio region is now only two beats, so the loop that keeps repeating is those two beats. (music playing) So if I make that go back out to its original size, I can drag out to a full eight beats, and my loops are now going to include all eight beats.
(music playing) So if you have trimmed your region, the Loop tool will only loop the part of the region that's currently visible, and will disregard any audio that's not currently revealed. When you want to trim or loop a region in your timeline GarageBand makes it easy by offering a context-sensitive cursor instead of a traditional toolbar.
