Apple Logic Pro 9 - Manual (Page 653)

The Piano Roll Editor shows the note events of a MIDI region as horizontal rectangles.
This resembles the holes cut in paper pianola rolls. The Piano Roll Editor can display the
MIDI note events of one MIDI region, or all MIDI regions in a folder or project. (See
Displaying Multiple MIDI Regions in the Piano Roll Editor .) You will generally work on one
region at a time in the Piano Roll Editor, however.
