The Piano Roll

Piano-Roll

The piano-roll editor displays notes in a grid where the vertical axis denotes the pitch and the horizontal axis the time line. It is modeled after a classic piano-roll. Several tools can be selected via a drop down menu or hotkeys which aid with creation, selection and modification of musical events. The cursor keys can be used to move selected notes, in combination with modifier keys the keys can also change note duration or note focus. A context menu is available with mouse button 3, which provides extended functionality.
