Chapter 1 Starting Your Project and Importing Media Files 17
You can consider the MIDI region a container for MIDI information. This can include—
either individually or in combination—note events, controllers, program changes, or
even SysEx for your MIDI tone generators. All MIDI event types are discussed in the
Logic user manual.
Important: The Arrange window only deals with regions—it does not allow you to edit
the MIDI events or audio information in regions! If you need to make precise changes
to the region content, you can do so in the editor windows. See “Editing MIDI Events”
on page 47 and “Editing Audio Files” on page 59.
These procedures (and the track creation method covered earlier) can be repeated
numerous times, allowing you to build huge arrangements—with hundreds of tracks,
and thousands of regions. You may freely drag and drop regions to any position in the
project, but remember that audio regions only play on audio tracks. MIDI regions only
play on software instrument or external MIDI tracks.
Apple Loop Types
As you’ve found out, there are two types of Apple Loops.
 Apple Loop audio files (blue icon) contain audio data and identification information;
time and date, category, mood, key and tempo, amongst others. They also contain
transient markers, which break them down into small time slices. The advantage of
Apple Loop audio files is their ability to automatically match the tempo and key of a
Logic project. You can only add these file types to audio tracks.
 (SIAL) Software Instrument Apple Loop files (green icon) also contain MIDI note
information—that triggers a musical phrase or riff. The motif will be played, as is,
when these types of Apple Loops are added to an audio track (in other words, they
behave just like the blue Apple Loop audio files). When added to an instrument track,
however, the MIDI note information can be edited, as you would with any MIDI
region. SIALs also contain instrument and effect setting information. When these
loop types are added to a blank instrument track (one with an empty channel strip),
a software instrument is automatically inserted into the Instrument slot.
Automatic Track Creation From Media Area Windows
The Loop Browser and Browser have a trick up their sleeve that can accelerate your
workflow.
To create a track and import a loop in one step:
m Directly drag an Apple Loop (of either type) from the Loop Browser into:
 An empty Arrange window (obviously, not applicable at this point).
 To the blank space below existing tracks.
A new audio or instrument track will be created, and the Apple Loop region will appear
in the Arrange area, at the dropped position.
