Choosing a Zoom Level in the Graphic Editor window You can click one of the Magnifying Glass icons in the Graphic Editor window to choose an appropriate zoom level. Zoom + (zoom in) allows you to see notes in greater detail, but you see fewer bars; Zoom - (zoom out) allows you to see a greater number of bars, but you see notes in less detail. If you hold down the Option key while you zoom in the Piano Roll, you will zoom vertically. See Also: The Graphic Editor Window Zoom In Zoom Out
