Grids are the vertical lines in the Composition area that allows you to see the bars and beats of your project. Zooming in and out allows you to adjust the grid sizes to your preference.
There are three ways of zooming in and out:
- Use the magnifiers in the lower right corner in the studio.
- Use Cmd/Ctrl+arrow left/right if you like using keyboard shortcuts.
- Use two fingers to zoom in and out if you have a touchpad.
