Piano Roll Editor overview
The Piano Roll Editor shows the notes in a MIDI region as colored bars in a time grid. Horizontal
lines show the time position, while vertical lines indicate pitch. A keyboard along the left edge of
the Piano Roll Editor provides a reference for the pitches of notes. The info display in the Piano
Roll Editor menu bar shows the note name and time position under the pointer.
The Piano Roll Editor can display the MIDI regions on a track, in a folder, or on multiple tracks in
the project. (See
View multiple MIDI regions in the Piano Roll Editor on page 361.)
