The Piano Roll

The Piano Roll view displays notes as bars along a timeline, much like an old player piano. The piano roll is the preferred method of editing MIDI for many people, either because they do not know how to read notated music or because they find it more intuitive andUseful.

The controls at the top of the window areUsed to specify which track and voice is currently displayed in the Piano Roll and Envelope View.

The Vertical Scale Controls in the lower right-hand corner of the piano roll areUsed to control the height of the bars in the Piano Roll, which affects how many pitches are visible. Vertical scaling also changes the height of the piano keys on the left side of the window.

The Envelope View and Controls at the bottom of the window areUsed to create and edit envelopes. An envelope is a representation of how a musical parameter, such as tempo, volume or balance, varies over time.
