418 Chapter 16 Editing MIDI Events in the Piano Roll Editor
Creating and Editing Note Events
Handling note events in the Piano Roll Editor is very similar to region handling in the
Arrange area. Many of the same techniques used to lengthen, cut, and move regions
apply to note events, so you should find much of this section familiar.
Snapping Edits to Time Positions
You move and resize events in the Piano Roll Editor because you want them to start
and end at a specific point in time.
Logic Express offers a snap feature that automatically aligns event start and end points
to a selected grid value, when you move or resize them.
To snap events to a grid:
m Choose one of the following values in the Snap menu at the top of the Piano Roll
window:
 Smart: Edit operations will snap to the nearest bar, beat, sub beat, and so on,
dependent on the current Bar ruler division value and the zoom level.
 Bar: Edit operations will snap to the nearest bar.
 Beat: Edit operations will snap to the nearest beat in a bar.
 Division: Edit operations will snap to the nearest division (this is the time signature
shown in the Transport and Bar ruler).
 Ticks: Edit operations will snap to the nearest clock tick (1/3840th of a beat).
 Frames: Edit operations will snap to the nearest SMPTE frame.
The Snap functionality is relative, which means that the edit operation will be snapped
to the nearest bar, beat, and so on—retaining the event’s distance from its original
position. As an example, if an event is placed at position 1.2.1.16 , and you move it to
around bar 2 (with the Snap menu set to Bar), it will automatically snap the event to
position 2.2.1.16 — ra ther than 2.1.1.1 (the bar 2 start point). You can override relative
snaps with the Snap to Absolute Value option.
