Split regions in Logic Pro for Mac

You can split a region in the Tracks area, and use the split segments of the region in different places in the Tracks area.

When you split a MIDI region, any notes at the split point are shortened to that point. If notes in a split MIDI region overlap other notes by more than a 1/16 note, a dialog appears, asking if you want to keep, shorten, or split the notes.

Splitting a Session Player region might change the pattern, depending on the Fills setting. After splitting, settings for the region segments can be edited independently in the Session Player Editor.

You can also split regions by selecting part of the regions using the marquee ruler. For information about selecting regions using the marquee ruler, see Select parts of regions in Logic Pro for Mac.

Split regions at the playhead position

In the Logic Pro Tracks area, select the region or regions you want to split.
Move the playhead over the point where you want to split the regions, then choose Edit > Split > Regions at Playhead.
The selected region is split into two regions at the playhead position. Only the selected region is split, even if a region on another track is under the playhead as well. If multiple regions are selected and are under the playhead, they are all split.
Tip: To cut at the nearest bar, use the Split Regions/Events by Rounded Playhead Position key command.

Split regions using the Scissors tool

In Logic Pro, select the regions you want to split.
Select the Scissors tool, then click and hold the regions you want to split.
The help tag shows the current split position.
Release the mouse button.
All selected regions are cut at the position shown in the help tag.

When selecting a cut point with the Scissors tool, you can move backward and forward in steps of one division. The grid is based on the Snap pop-up menu setting.

Split regions at the locator positions

In Logic Pro, set the left and right locator positions.
Select the regions you want to divide within the locator boundaries.
Choose Edit > Split > Region(s) by Locators (or use the Split Regions/Events by Locators or Marquee Selection key command).
All selected regions located wholly, or partly, between the locators are cut at the left and right locator positions. All regions created between the locator positions as a result of the Split operation are then automatically selected.

Tip: You can achieve the same effect by defining a cycle with the pointer in the ruler, while holding down Command.

Split regions at the marquee selection border

In Logic Pro, choose View > Marquee Ruler from the Tracks area menu bar.
Drag in the thin marquee area of the ruler to select parts of one or more regions (also shown on selected tracks).
Control-click the marquee ruler, then choose Split Regions/Events at Locators or Marquee Selection from the shortcut menu.

Split a region into portions of equal length

In Logic Pro, press and hold Option while cutting a region with the Scissors tool.
A plus sign appears next to the Scissors tool.
The selected region is cut into several pieces—each the same length as the first segment.
For example, to divide a 16-bar region into eight 2-bar regions, cut the region at the start of bar 3, while holding down Option.

Handle overlapping notes in split MIDI regions

If any notes in a split MIDI region overlap other notes by more than a 1/16 note, a dialog appears, asking if you want to keep, shorten, or split the notes.

In Logic Pro, select one of the following options:
- Keep: Leaves all notes unaltered. The MIDI region is cut as intended, but there may be notes in the left half (earlier region) that are much longer than the MIDI region containing them. Such notes play normally, unless Clip Length is activated. (See Delay region playback in Logic Pro for Mac.)
- Shorten: Truncates all overlapping notes, so that they end at the point where the original MIDI region was split.
- Split: Splits overlapping notes across the two MIDI regions; two notes are created, with the same pitch and velocity as the original, and with the same total length as the original note.

When you split a region containing region automation, Logic Pro adds automation points at the split points. For information about region automation, see Track automation vs. region automation in Logic Pro for Mac. For information about working with automation points, see Add automation points to tracks in Logic Pro for Mac.

You can split an audio recording into segments based on amplitude levels, using the Audio > Remove Silence function in the toolbar. For details, see Remove silent passages in Logic Pro for Mac.
