338 Chapter 13 Creating Your Arrangement
 Each of these regions 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.
To split MIDI regions by note pitches:
1 Select the desired MIDI regions.
2 Choose Region > Split/Demix > Demix by Note Pitch (or use the corresponding key
command).
Logic Pro searches the selected MIDI regions for notes with different note numbers.
 A different MIDI region of the same length is created for every note number found.
 Tracks are created for these MIDI regions, and all are assigned to the same channel
strip as the original MIDI region.
This feature is especially useful for separating drum parts that have been recorded into
Logic Pro from a drum machine—where all notes are on the same MIDI channel. Each
note region can then be assigned to another channel strip, or perhaps some can be
deleted, to thin out the original drum pattern.
Using Folders
A folder is a region that can contain other regions, much like a folder in the Finder can
contain other folders or files. In principle, you can edit folders as you would edit MIDI
regions.
One way to visualize a folder is as an arrangement within an arrangement. A folder can
contain as many tracks, featuring regions, as required. A closed folder looks like a MIDI
region, but is placed on a track assigned to a folder in the track list, rather than a
channel strip.
When opened, folders look just like the Arrange area and track list in a project.
