AU Manager
Logic Express 7 uses Apple’s AU Validation Tool to ensure that only Audio Unit plug-ins
which pass the test are used in Logic.
The scan process takes place automatically when you launch Logic Express 7. You can
see the results of the validation scan for all Audio Units plug-ins via the Logic
Application menu: Preferences > Start Logic AU Manager.
Note: Logic Express 7 automatically quits before the Logic AU Manager is launched.
Logic will automatically restart after you quit the Logic AU Manager.
The Logic AU Manager allows you to disable Audio Units plug-ins that you don’t want
to use in Logic, even if they pass the test. Simply uncheck the corresponding checkbox
in the Use column to disable any plug-in. You can store your choice of Audio Units
plug-ins by clicking OK.
The results of the test are shown in the Compatibility column. Audio Units plug-ins that
“failed” the validation test, can be enabled—but be aware that these plug-ins can
cause problems. Use of plug-ins that have failed the validation can negatively affect the
test results of subsequently scanned plug-ins, can cause Logic crashes or even lead to
data loss (destroyed song files).
We strongly recommend that you check the manufacturer’s website for updated
versions of Audio Units plug-ins that fail the validation.
Note: If you press Control-Shift while launching Logic, the AU Safe Mode will be used:
Only plug-ins that pass the validation test will be used; manually activated plug-ins that
failed the validation test will not be available.
Click “Reset & Rescan All” to run another validation test, after installing plug-ins/
updaters or moving components in the Finder, while Logic or the AU Manager are
open. You can also rescan individual plug-ins—in cases where you’ve installed an
updated version. Updated plug-in versions will automatically be tested the next time
Logic is launched. They will be enabled automatically, if they pass the validation scan.
Loop Browser
The Apple Loops Browser also displays Acid and ReCycle Loops, and has therefore been
renamed Loop Browser. Loops with sample rates that don’t match the song sample rate
can be used.
Acid Loops don’t contain “tags” like Apple Loops. Apple Loop tags identify the
categories/styles that a Loop appears in, within the Loop Browser.
2
In Acid Loops, this information is derived from the surrounding folder structure
(especially the names of folders), which must comply with certain standards. This
means that it’s not possible to drag an individual Acid Loop file into the Loop Browser.
As such, you need to drag the entire CD (or folder) that contains the Acid Loops into
the Loop Browser.
Display of Loops
All loops that follow the song key and tempo are indicated by the following symbols in
Logic:
Apple Loops Utility
If you open an Audio Region with a length that does not match the bars or beats in the
Apple Loops Utility, the following dialog appears:
There are two possible reasons for the wrong length:
• The audio recording was recorded at the song tempo, but not cut correctly. In this
situation, you can shorten the recording, via the dialog.
• The loop uses a different tempo: in this case, you can set the length of the audio
loop in the Loop length box and choose “Use set length.”
Support of Apple Lossless Files
Logic Express 7 supports Apple Lossless files. This lossless file format uses an audio
codec that retains the full quality of uncompressed CD audio, while requiring only
about half the storage space. The Apple Lossless Encoder can be used for importing
music from CDs in iTunes, for example.
3
Loop Length Editing
Logic’s Loop function has been enhanced with an easy to use Loop Length Editing
function.
To set the length of a looped Region:
1 Move the cursor to the end of the Region that you want to loop. The cursor will change
into a circular arrow (a loop) when positioned in the upper area of the Region.
2 Click-hold and drag the end of the Region to the desired length.
Note: Whenever you move the cursor into the upper half of the looped area, it changes
to a circular arrow, allowing loop length changes. If you want to select the looped
Region (to move it, for example), click in the lower half of the looped area. You can also
Shift-click in the upper loop area to select the Region.
The cursor will only turn into the circular arrow (and offer the Loop Length Editing
functions), when the track is of sufficient height. If the track height is minimal, Optionclick on the end of the Region to access the Loop Length Editing function. This also
applies if automation data is visible on a track.
Important: Deactivation of the Region Loop parameter resets the loop length. The next
time the Loop parameter is used, the Region is repeated until it encounters another
Region on the same track or the Song End point is reached.
Create Multiple Tracks
This facility, accessible via the Tracks > Create Multiple menu option in the Arrange
window, does exactly what it says. When selected, a dialog box opens, allowing you to
choose the:
• Driver: This pull-down menu allows you to select the audio hardware driver that you
wish to use for your newly-created tracks.
• Track Type: This pull-down menu allows you to select between Audio, Audio
Instrument, and Auxiliary tracks.
• Number of Tracks: Type in the desired number of tracks. Eight is the default.
• Mode: Simply click on the desired Mono or Stereo radio button, to create multiple
mono or stereo tracks of the chosen type.
The Create Multiple Tracks function is intelligent in the way it handles tracks, and
underlying Audio Objects. To explain; imagine a song that contains four audio tracks in
the Arrange, but there are actually eight Audio Objects set up on the Environment’s
Audio Layer. Use of the Create Multiple Tracks function to add another four tracks to
the Arrange will work as expected. The four existing tracks use Audio Objects 1 to 4,
and the newly-created tracks use Audio Objects 5 to 8.

Using the same example, but adding eight tracks with the Create Multiple Tracks
function, behaves a little differently. The four existing tracks use Audio Objects 1 to 4.
The newly-created tracks use Audio Objects 5 to 8, and new Audio Objects (9 to 12) are
automatically created on the Environment’s Audio Layer.
This facility makes the setup of additional tracks much faster than in previous Logic
versions, where new Audio Objects and Arrange window tracks needed to be created,
and assigned, before use.
Control Surfaces (Controller Assignments)
The Easy View of the Controller Assignment window has been simplified. The Control
Name field has been removed, because Easy View is generally used for unsupported
control surfaces—such as the controllers on your master keyboard or other fader
boxes.
The Track parameter allows you to choose between selected (which is the default, if
creating assignments on the selected track) or a fixed track number (if you want to set
up your controls as a mixer surface).
The Learn Message button has been renamed to Learn Mode (because you can create
multiple assignments while it’s enabled).
Assignments created for a specific plug-in are only active if the plug-in is present on
the specified track. This enables you to use the same controller messages for different
plug-ins—control the cutoff frequency of ES1, ES2, or EXS24 via the same knob—
depending on which software instrument is inserted in the selected track.
Your assignments are stored as preferences, making them available in all songs.
Updated File Paths
The location of all files (preferences, plug-in settings and so on) associated with
Logic Express 7 have changed. Unlike older versions, Logic Express 7 does not use the
program folder as the location for any associated files.
Logic Express 7 complies fully with Mac OS X standards:
Pre Installed Files
All pre-installed files are located in the local domain: YourHardDiskName
It is usually prefaced with a: / (at the beginning of a path).
User Created/Editable Files
All files that can be directly written by the user are located in the user domain:
YourHardDiskName/Users/YourUserName.
It is usually prefaced with a: ~/
5
Preferences
All preference files are installed in: ~/Library/Preferences/Logic
The main preference file is named: com.apple.logic.express
Other Logic Express 7 preference files are also found in this folder.
Song Templates
Logic Express 7 scans for a folder named “Song Templates” in the following folder:
~/Library/Application Support/Logic.
Logic Express 7 then searches for the “Autoload” or “Autoload.lso” song in:
/Library/Application Support/Logic.
Plug-in Settings
Logic Express 7 scans for a folder named after the plug-in (“PlugInName/“) in the
following folders, and order:
• ~/Library/Application Support/Logic/Plug-In Settings
User-defined or edited settings are always stored here. These settings appear in the
top level of the Settings pop-up menu in Plug-in windows. “Save Setting as” defaults
to this level. “Save Setting” only works on settings located at this top level (otherwise
a “Save Setting as” is performed).
• /Library/Application Support/Logic/Plug-In Settings
Factory settings are installed here. If Logic Express 7 also finds settings in one of the
other locations, the settings found here appear in the “Factory” subfolder of the
Settings menu.
• /Applications/Logic 6 Series/Plug-In Settings
The setting files of the Logic 6 Series were always stored here. If Logic Express 7 also
finds settings in one of the other locations, the settings found here appear in the
“Logic 6 Series” subfolder of the Settings menu.
We recommend that all old settings be moved from this folder to the new location for
user settings (~/Library/Application Support/Logic/Plug-In Settings). You can do this
with a drag and drop in the Finder, or in Logic; by loading the settings, and saving
them to the new location (which is the default location of the “Save” or “Save as”
dialogs).
Default Settings
Like earlier versions, Logic Express 7 allows you to use a default setting file that
automatically loads when opening a plug-in. This file must be named “#default.pst”, and
is searched for in: ~/Library/Application Support/Logic/Plug-In Settings/PlugInName.
This is where you can save your own default setting. Simply save a setting called
“#default.pst”.
If not found, Logic Express 7 looks in /Library/Application Support/Logic/Plug-In
Settings/PlugInName/ and then /Applications/Logic 6 Series/Plug-In Settings/
PlugInName.

GarageBand Instruments
Logic Express 7 searches for GarageBand Instruments in the: “Plug-In Settings/
PlugInName” folder in the following directories, and order:
• ~/Library/Application Support/Logic/Plug-In Settings/PlugInName
User-defined or edited settings are stored here.
• /Library/Application Support/GarageBand/Plug-In Settings/PlugInName
“Factory” settings are stored here.
Channel Strip Settings
Logic Express 7 scans for a folder named “Channel Strip Settings” in the following
folders, and order:
• ~/Library/Application Support/Logic
User-defined or edited Channel Strip settings are stored here.
• /Library/Application Support/Logic
Factory settings are always stored here.
Logic Express 7 also scans the following folder path for Track and Instrument Audio
Objects:
/Library/Application Support/GarageBand/Instrument Library/Track Settings.
EXS Instruments
Logic Express 7 scans for a folder named “Sampler Instruments” in the following folders,
and order:
• ~/Library/Application Support/Logic
User-defined or edited instruments are stored here.
• /Library/Application Support/Logic
Factory EXS Instrument files are installed here.
• /Applications/Logic 6 Series
EXS Instrument files of the Logic 6 Series are always stored here.
• …/SongOrProjectName
As in earlier versions, Logic Express 7 also searches for EXS Instruments in the project
or song folder.
Logic Express 7 also looks in:
/Library/Application Support/GarageBand/Instrument Library/Sampler.
EXS Sample Conversion
These are the default locations for converted samples of different formats:
• ~/Library/Application Support/Logic/AKAI Samples
For samples converted from AKAI format.
• ~/Library/Application Support/Logic/DLS-Giga Samples
For samples converted from GigaSampler/GigaStudio format.
• ~/Library/Application Support/Logic/SoundFont Samples
For samples converted from SoundFont format.
7
Apple Loops Library
Logic Express 7 shares the Apple Loops Library with GarageBand. It uses the Apple
Loops folders found in these locations:
/Library/Application Support/GarageBand
Used for the Apple Loops library that ships with Logic Express 7 or GarageBand. The
content of any additional Jam Pack libraries is also installed here.
Important: Don’t delete this folder—even if you decide to remove GarageBand from
your hard disk! At least be aware that this will also remove content from Logic’s Loop
Browser.
~/Library/Application Support/GarageBand
Used for user-created Apple Loops made with the Apple Loops Utility (which might
also be named “Soundtrack Loop Utility”—found in your Utilities folder inside the
Applications folder).
Apple Loops dragged from the Finder into Logic’s Loop Browser window, coupled with
the “Copy to Library” option, copies the Apple Loops to this location. Alternatively,
additional Apple Loops can be kept in their original Finder location.
User Icons
~/Application Support/Logic/Images/Icons
The format for user icons remains .png. The filename needs to start with xxx (where xxx
is a 1 to 3 digit number). Correspondingly numbered default icons will be replaced by
your personal icons.
I/O Labels
The user-definable I/O Labels (the “IO Labels CoreAudio” file) are located in:
~/Library/Application Support/Logic.
This is the automatic file save location. If not found, Logic Express 7 also searches:
/Applications/Logic 6 Series.
Control Surface Plug-ins
Control Surface plug-ins are installed (and searched for) in the application bundle.
You can install additional Control Surface plug-ins in:
~/Library/Application Support/MIDI Device Plug-ins.
Tuning Tables
Logic Express 7 scans for a folder named “Tuning Tables” in the following folder:
/Library/Application Support/Logic.
8
Default Directories
• ~/Music/Logic
For Logic Express 7 songs (Open/Save/Save as).
• ~/Movies
For Movie files (Open).
• ~/Pictures
For the Camera tool in the Score Editor (Save Bitmap File as).
Manual Corrections
The following section contains a number of manual corrections where functionality
was altered after writing, or was incorrectly documented.
Freezing tracks using DSP-card based effects
The Logic Express 7 Reference manual incorrectly states that you cannot freeze tracks
that make use of DSP-card based effects (PowerCore and UAD1, for example). You may
freeze such tracks.
Opening non-floating Plug-in window
The Logic Express 7 Reference manual states that Shift-double-clicking a used Insert
slot will open a non-floating Plug-in window. This is incorrect. The correct shortcut is
Control-Option-double-click.
Exporting Logic 4.8 songs
The Logic Express 7 Reference manual discusses the export of Logic 4.8 format songs.
This cannot be done directly in Logic Express 7. You can, however, use Logic 6.4.3 to
open a Logic Express 7 song, and use the Logic 4.8 Export function available in this
Logic version (6.4.3).
Warning: It should be noted that some data (such as automation) will be lost during an
export to a Logic 4.8 song.
Input Objects in Logic Express
The Audio Input Objects described in the Logic Express 7 Reference manual do not
exist in the application.
Note Velocity Hyper Draw in Logic Express
Hyper Draw for note velocity described in the Logic Express 7 Reference manual on p.
236 and on p. 348 does not exist in the application.
Record Enable buttons in Logic Express
Record Enable buttons for Audio Instrument and MIDI tracks described in the Logic
Express 7 Reference manual do not exist in the application.
