Overview of the Piano Roll Editor in Logic Pro for Mac

In Logic Pro for Mac, the Piano Roll Editor shows the notes in a MIDI region as color-coded bars in a time grid. Horizontal lines show the time position and note length, and the vertical position indicates pitch. A keyboard along the left edge of the Piano Roll Editor provides a reference for the pitches of notes. The info display after the tool pop-up menus in the Piano Roll Editor menu bar shows the note name and time position under the pointer.

Some software instruments—most often, drum and percussion instruments—provide names for the MIDI notes (for example, if the MIDI note G#2 plays a cowbell, the instrument displays “Cowbell” next to the keyboard at the left edge of the Piano Roll Editor). When displayed MIDI regions are played back by an instrument that provides note names, you have the option to show only those note names (called “Drum Names” in Logic Pro), in which case the keyboard is replaced by a table showing those note names.

You can also switch to Collapse Mode view, which shows only those lanes in the Piano Roll Editor that are used by notes in the MIDI regions you’ve selected.

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 regions in the Piano Roll Editor in Logic Pro.

You can record notes into the Piano Roll Editor directly when the MIDI In button is activated using step recording techniques. See Use step input recording. Make sure the MIDI Out button is activated so that you can hear notes that you add, select, or click.

You can open the Piano Roll Editor as a pane in the main window, or as a separate, resizable window.

Open the Piano Roll Editor

In Logic Pro, do one of the following:

  • Select a software instrument (or external MIDI instrument) track or a MIDI region, then click the Editors button .

    The Piano Roll Editor opens below the Tracks area. On the left are controls for quantizing the timing and pitch of MIDI regions, adjusting their pitch, and editing the velocity of MIDI notes. Along the top of the Piano Roll Editor is a ruler showing time divisions, and a menu bar with local menus, tools, and other controls. The header shows the name of the selected region (or the number of regions, if more than one is selected).
