Using the piano roll editor
The piano roll editor is an OPT plug-in that you can use to create and edit note events within the Clip Properties window for a MIDI clip.
The top pane of the piano roll editor displays note information like a sequencer or a roll from a player piano. Each note is represented by
a rectangular note event of a certain length and pitch. The piano keys along the left side of the window indicate the pitch of a note
event. The beat ruler across the top of the window shows the length and location of a note event.
The lower pane of the piano roll editor displays velocity information for each note event. A transport bar for previewing MIDI appears at
the bottom of the window.
