50 Chapter 5 MIDI Regions
The Matrix Editor
Although it looks very different, the Matrix Editor is quite similar to the Arrange
window. Unlike the Arrange window—MIDI note events, rather than MIDI Regions—are
displayed as horizontal bars in the Matrix editor. Editing, you’ll discover, is quite similar.
The illustration above shows a MIDI Region with chords displayed in the Matrix Editor.
The keyboard along the left edge of the Matrix Editor indicates the pitch of the notes/
keys played in the display. A chord is represented by a group of overlapping bars.
As you can see, the position and length of notes are clearly visible in the Matrix Editor.
The display can be zoomed horizontally and vertically with the two Zoom controls, just
as in the Arrange window.
Note: When making changes in the Matrix—or any other Logic editor—you can hear
the changes in real-time. This is achieved by activating the MIDI Out button found
towards the top left of each editor window (see picture below). We suggest that you
activate this button by clicking on it. It is illuminated when active.
To change note lengths in the Matrix Editor:
1 In the Matrix Editor, you can change the length of single notes or multiple notes.
Highlight the desired note(s) by clicking on it/them (with Shift held) or by rubber-band
selecting it/them.
2 Grab the lower right corner of one of the selected notes, and drag it to the desired
length. Release the mouse button.
