The Trim tool and the Grabber tool are both very handy for editing automation data. Let's check it out. I am going to zoom in on some volume automation on this bass track here and I am going to get the Grabber. And the Grabber is great for creating and moving individual break points. When you bring the Grabber down onto an automation like this, it turns into a pointer, and now with the pointer, I can click and add break points. I can also click and drag and move those break points around. With the Trim tool, you can actually move entire sections of the automation data.
So I am going to choose the Trim tool here, and if I click and drag on this line right here, you'll see the volume going down, and we see the actual volume level and we see the difference from where it was. The little triangle that we see here, that's the delta. It's the difference between the original value and the trimmed value. Si if I let go of that, it brings that whole volume automation line down. With the Trim tool, you can also bring the overall track level up or down, while keeping all of the relative automation data.
So I am going to zoom out, and now I am going to select an area right here and then use the Trimmer to bring that entire automation line down. So I click and drag and all the volume automation data goes down relative to each other. So you see that I brought this entire line down -12.5 dB. So the shape of the automation stays the same. If we go over to the edge of the selected region--and I will zoom in on it here-- you see that there's a break point there.
Now if you don't select a clip with end points like we did here, Pro Tools will create a new end point before and after the selected area, as it's done right here. If I undo our trim automation, you are going to see that data point go away. And if you want to suppress the creation of these break points, you can press Alt in Windows or Option on the Mac while you are using the Trim tool. I'll show you this. I am going to zoom out and now bring this down while I am pressing the Option key on the Mac or the Alt key in windows, and you'll see that this area won't get a break point; it will actually go over to this breakpoint and be based on that, check it out.
Click and drag. So I have suppressed the break point being created here. Now if you want to raise the volume of one entire clip, you can use the Clip Gain function. And let's switch over to waveform view here, and we will show the Clip Gain Line. Now with the Trimmer, we can literally go and trim this entire clip gain line and this is separate from our volume automation. So we can retain both the volume automation and the clip gain.
As you can see here, the Trim tool and the Grabber tool both have a lot of uses in the realm of automation. Practice using them with the techniques I have showed you here and you be able to edit automation very quickly.
