GarageBand ’11 provides an automation curve for controlling the track volume, track pan, and automated mixing settings over the duration of a song. You can raise or lower the volume of a track at specific points to simulate a crescendo or decrescendo, to make specific tracks fade in or out, or even to hide a bad note by lowering the volume in the track at that moment.
To set an automation curve for Track Volume, follow these steps:
- Click the Curves (triangle) button in the track header, and choose Track Volume from the pop-up menu.
- Click the rectangle next to Track Volume to turn it on or off.
- Click the line to create several points, and then drag each point to define a curve.A setting of 0 indicates even volume, dragging up into positive numbers increases volume, and dragging down into negative numbers decreases volume. The volume changes evenly between points on the volume curve, providing smoother volume control for the track.
Click and then drag a point on the automation curve for Track Volume.
