Chapter 13 Creating Your Arrangement 351
2 Choose Region > Merge > Regions per Tracks (or use the corresponding key
command).
The selected regions are combined into one region per track. As an example, tracks 1 to
4 have regions that you’d like to merge. Make your region selections in each track lane,
press Shift-J, and four merged regions will be created—one for each track.
What Happens When MIDI Regions Are Merged
When you merge MIDI regions:
 All events from each individual MIDI region retain their original time positions.
 The new (merged) MIDI region adopts the name and track of the first (along the time
line) of the original MIDI regions.
 The Transposition, Velocity, and Dynamics region parameters—if not identical in all
selected regions—are normalized before the merge. This means that all parameter
values are written as data changes for each region before the merge. The parameters
of the newly created (merged) MIDI region are all set to neutral (default) values.
 If one of the region parameters (the Transposition value, for example) is set
identically in all selected regions, that value is preserved in the Region Parameter box
for the merged region, and the events remain unchanged from their original values.
Note: Be aware that the individual MIDI channels of events (if applicable) are replaced
by the MIDI channel of the current track Instrument channel strip.
Merging Audio Regions
Merging audio regions is a non-destructive operation, as Logic Express always creates a
new file for the merged audio material (sometimes called a mixdown).
This new audio file is stored (in the project folder) on your hard drive and is
automatically added to the Audio Bin. The merged region replaces the original regions.
