GarageBand Scroll and zoom in the Tracks area
Depending on the size of the project and your display, you may not be able to see the entire project at one time. You can scroll horizontally and vertically in the Tracks area to view other parts of the project.
You can zoom in to make precise edits and see more detail in the Tracks area, or zoom out to view more of your project.
Scroll in the Tracks area
To scroll horizontally, drag the horizontal scroll bar in the Tracks area menu bar. Drag left to scroll to an earlier part of the project, or drag right to scroll to a later part of the project.
If a project has more tracks than are currently visible in the Tracks area, a vertical scroll bar appears along the right edge of the Tracks area. Drag the scroll bar up or down to see the other tracks.
Zoom in the Tracks area
Drag the horizontal zoom sliders, located in the ruler.
