Get started with the Piano Roll Editor
The Piano Roll Editor shows the notes in MIDI regions on a software instrument track as colored
bars in a time grid. On the grid, a note’s horizontal position indicates where the note starts
playing, while its vertical position indicates its pitch. A keyboard graphic along the left edge of
the Piano Roll Editor provides an easy guide to the pitches of notes.
On the left are controls for quantizing the timing and pitch of MIDI notes, and editing their
velocity. Along the top of the Piano Roll Editor, a ruler shows time divisions, based on the time
format chosen in the LCD. The header shows the name of the selected region, or the number
of regions (if more than one is selected), as well as the pitch and position of the pointer in
the region.
