Changing the Track height

How do I change the track height on my Chromebook? I have none of the icons people are directing me to.

On a Chromebook, if you want to change the height of all tracks, i.e. zooming in vertically, pinch with two fingers on the screen (if it’s a touch screen) or on the trackpad. To zoom horizontally with the trackpad pinch while holding the Ctrl key pressed.
You cannot currently change the height of a single track, you can however use the magnifying glass icon in the track’s top left corner to enlarge a track by a fixed amount.


Thank you. I have already tried that numerous time to no avail. After many frustrating weeks of just trying to “create” 1 song, I just cancelled and deleted the app.
