The Piano roll feature is located at the bottom of the screen and has a very small working area. There are a few ways to get more work space into it. One of them is to click and drag the upper extremity of the pane, till you get sufficient space. By default, the view is zoomed into a small section of the timeline. Click the [ -] button, right next to the scrollbar ro zoom out and the [ +] to zoom in. There is a zoom butron on the top section of the Piano roll pane. Ultimately, you can also make the Piano pane much larger, by pressing the maximise button-the same button will do the trick for all other panes.
