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 the Logic Pro Tracks area.)
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-based automation, automation points are added
at the split points. For information about region-based automation, see Track-based vs.
region-based automation in Logic Pro. For information about working with automation
points, see Add and adjust automation points in Logic Pro.
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 a
Logic Pro project.
Demix MIDI regions in the Logic Pro Tracks area
You can split, or demix, a MIDI region (or a standard MIDI file of format 1 or 0) into separate
regions by event channels or by note pitch.
Split MIDI regions by event channels
1. In Logic Pro, select the MIDI regions you want to split.
2. Do one of the following:
Choose Edit > Separate MIDI Events > by Event Channel from the Tracks area menu
bar (or use the Separate MIDI Region by MIDI Channel key command).
Control-click the MIDI region, then choose MIDI > Separate by MIDI Channel from the
shortcut menu.
A separate MIDI region is created for every MIDI channel found, containing all
matching events. Each region is created on a track with an instrument channel that
matches the MIDI channel. If no such tracks exist, new tracks are created for each
channel.
