You've decided to use a pre-recorded audio region as the basis for your new project. Describe an issue that is likely to occur in this type of situation and give its solution.
ISSUE:
It's not likely that the tempo of the audio region will match the default new-project tempo of 120 BPM. If the pre-recorded audio region has not been added to the Apple Loops Library, it won't automatically adjust its tempo or key to your project when it's dragged onto the track.

SOLUTION:
The tempo of the new project must be adjusted from 120 BPM to match the tempo of the pre-recorded audio region.
You're in Browser tab > Browser View and you've double-clicked on an audio file icon. What occurs?
An audio region is created on the selected track at the playhead position.
Two ways that you can tell that an audio loop's tempo and project's tempo are out of sync.
1. Visually, the beginnings of loop repeats won't align with downbeats on the Bar ruler.
2. Turn on Metronome [Transport bar > click Metronome button] and start playback in the Arrange area. You'll hear that they're out of sync.
You're ready to adjust your project tempo so it matches the audio file tempo. What's your first step?
You need to create a cycle area equal to the length that you want your audio file to match once the tempo is adjusted.

In other words, you need to create a cycle area length equal to the audio file's length.
You're matching project and audio file tempos and your audio loop is two bars. To what length should your cycle area in the new project be set?
. . . two bars
When making the project tempo match the audio file tempo, Logic calculates the new project tempo so that. . .
. . . the lengths of the audio region and project cycle area are equal.
When tempo matching, the feature in Logic that forms the link between audio file tempo and new project tempo is the . . .
. . . length of the cycle area

What would have been the result if you had added Apple Loop to the timeline without first having matched the audio file and project tempos?
Don't know yet.
What audio file format types are Apple Loops?
AIFF [Audio Interchange File Format]
or
CAF [Core Audio File]
The fact that Apple Loops are audio files that contain additional information gives them two advantages. What are they?
1. They'll match the key and tempo of a Logic project
2. They can be searched from the Search Field in the Loop Browser
To what advantage is it to the user that Apple Loops contain additional descriptive information?
This information allows you to use the Loop Browser to search large libraries of Apple Loops by selecting or entering descriptors.
When you add an audio region to the Apple Loops Library, you enter additional information allowing the loop to become indexed and searchable. Name four of the six informational items you provide.
1. Name
2. Type
3. Scale
4. Genre
5. Instrument Descriptors
6. Tags (Clean, Acoustic, Relaxed. . . )
Besides Logic, what two other applications support Apple Loops?
GarageBand
and
Soundtrack Pro
What happens when Apple Loops are imported into an application that does not support them?
. . . they behave like AIFF [Audio Interchange File Format] audio files.
Name the three menus at the top of the Loop Browser.
1. View
2. Signature
3. Scale
Name two brand name Apple Loop collections.
1. GarageBand
2. Jam Pack
At the upper right of the Loop Browser, there are three View buttons. Name them
1. Column
2. Music
3. Sound Effects
In the Loops tab, explain the difference between choosing the Music View or Sound Effects View buttons as opposed to Column View button.
Music or Sound Effects views display only a portion of all descriptors.

Column View displays all descriptors by Genre, Instrument or Mood.
The bottom portion of the Loop Browser is called . . .
. . . the Search Results list
Filtering in the Loop Browser can be fine-tuned by . . .
. . . typing another descriptor in the Search Field.
The more the playback key and tempo become further removed from that of the original loop, the more . . .
. . . artifacts are introduced.
The default key of a new project is . . .
. . . C Major
Within the Loop Browser below the Search Results list you'll find two preview settings. What do they do?
They allow you to change the volume and key of the loop that you're previewing.
When a loop whose original key is E major is dragged and inserted into a track of a new project, what key does is play in?
. . . C major
Why is it preferable to choose a loop whose key and tempo are close to those of the project's key and tempo?
. . . to reduce the amount of processing necessary to match the loop to the project.
List the steps involved in changing a project's key signature.
1. Select a region whose key is to be changed.
2. At the top left of the Arrange area, click the Global Tracks disclosure triangle.
3. Double-click the key signature.
4. Choose desired key from the pop-up.
At the upper left of the Arrange window, there is a disclosure triangle to the left of Global Tracks. Clicking on this triangle displays three underlying tracks. Name them.
1. Marker
2. Signature
3. Tempo
Once you've globally changed the key signature of the project, how does this affect subsequently imported Apple Loops?
. . . It ensures that they will play at the new project key.
How do you resize the Loop Browser category buttons area?
. . . drag the two horizontal lines between the Search Results list and the Loops Browser category buttons area.
Describe three ways you can customize the category buttons in Loops tab > Loop Browser > Music view.
1. Drag the button to desired position.
2. Control-click a button and a shortcut menu appears allowing you to choose from categories not currently visible in Music view.
3. Mark a loop as a Favorite and it will appear in the Search Results lists when you click Favorites.
List two advantages that customizing your category buttons provides.
1. You won't have to display as many category buttons.
2. You can resize the buttons area so you can see more loops in the Search Results list.
If you've resized your Category buttons area in the Music or Sound Effects view of the Loop Browser, how can you access the hidden buttons?
Click the button on the lower right with the >> icon.
If the result of your creation is a blue Apple Loop, what have you used to create it?
. . . you've used an audio region
What is the use restriction concerning Blue Apple Loops?
Blue Apple Loops can be used only as audio regions on audio tracks.
When creating a blue Apple Loop, there is a restriction on region length. What is it?
The region length in bars must be a whole integer.
After you've chosen Region > Add to Apple Loops Library and completed entries in the dialog and pressed Enter. Two Progress indicators appear one after the other. What are they telling you?
1. The Apple Loops file has been created.
2. The loop is indexed in the Loop Browser.
Once an audio file has been converted to a blue Apple Loop, it will have three advantages. What are they?
1. It can be accessed from any project as you can any other Apple Loop.
2. It can be previewed and played in different keys.
3. It will match the key and tempo of the current project.
How are green Apple Loops created?
. . . by using MIDI regions on a software instrument track
What types of audio file formats are green Apple Loops?
AIFF [Audio Interchange File Format]
or
CAF [Core Audio File]
In what sense are the green Apple Loops similar to blue Apple Loops?
They can be used as audio regions on an audio track.
Green Apple Loops are unique in that they can be used in two ways. How?
1. They can be used as audio regions on an audio track.
2. They can be used as MIDI regions on software instrument tracks.
Name three things that occur when you drag a green Apple Loop to [bar 1] the Arrange area.
1. A new software instrument track is created.
2. The loop's channel strip setting is loaded.
3. The loop's MIDI region is inserted on the new track.
Once a green Apple Loop is inserted into a software instrument track, green Apple Loops have one advantage over blue Apple Loops. What is it?
You can still edit the MIDI region or tweak the channel strip setting.
That fact that you can still edit the MIDI region or tweak the channel strip setting once a green Apple Loop is inserted into a software instrument track gives you some flexibility over blue Apple Loops. How so?
You could use the new software instrument channel strip settings, and program or record a new MIDI region that might work better with the song.

When previewing green vs. blue Apple Loops, what's the basic difference in how each can be utilized?
With green Apple Loops, you can use the software instrument channel strip setting and/or its MIDI region.
With respect to tempo, how does the behavior of audio files differ from that of all Apple Loops and MIDI regions?
Audio files won't follow tempo changes or variations unless you force them to do so.
Explain the meaning of "4 Selected" at the top of the Inspector's Region Parameter box.
You must have clicked on a track header of a track that contains four regions. [When you click a track header, you select all the regions on that track.]
Where is the "Follow Tempo" checkbox located?
. . . at the top of the Region Parameter box
You've recorded an audio file and added it to your project. You later decide that the project tempo should be changed. What's the potential problem and the solution?
Problem:
Audio recordings won't follow along unless you force them to do so.

Solution:
1. Select the region(s) on the audio track.
2. Click the Follow Tempo checkbox on the Inspector's Region Parameter box.
In order to make a region Follow Tempo, which region parameter does Logic adjust?
It adjusts the region's length.
Visually, how can you tell a region has had its tempo adjusted so it follows the project tempo?
The icon next to the region's name turns into a double arrow.
The drawback to having regions "Follow Tempo" is that . . .
. . . you can't apply crossfades.

Crossfades you previously created between regions disappear.
Inserting tempo changes and tempo curves throughout a project can be accomplished by using . . .
. . . the Global Tracks > Tempo track
How does the Tempo track within Global Tracks display tempo changes?
. . . as nodes
You're in Global Tracks > Tempo track and see a node followed by a horizontal line for the remainder of the project. What does this signify?
. . . that the project plays at one tempo.
How do you adjust the tempo in Global Tracks > Tempo?
Position the pointer over the tempo line. The pointer turns into a Hand tool. Drag tempo line vertically to adjust tempo.
How many Alternative tempo maps does Logic provide in Tempo track?
Nine
Which tool is used to insert tempo changes in Global Tracks > Tempo?
Pointer tool
What's the advantage of using only the Pointer tool to create a tempo change in Global Tracks > Tempo?
It lets you insert the tempo change and change its value in one operation.
How do you create a tempo curve between two nodes?
1. Position the Pencil tool over the deep blue node, which will be located above or below the second of the two nodes. The Pencil tool will change into a pointer.
2. Drag the deep blue node toward the left and up.
With respect to tempo variations, do some types of musical material react better than others?
Percussive material reacts better than melodic or harmonic material.

Explain how (A) "Matching the Project's Tempo to an Audio Region's Tempo" can be looked at as the reverse of (B) "Time Stretching an Audio Region."
In type (A) situation, the tempo of an audio file is being used to form the basis of a new project, whose default tempo is 120 bpm. Therefore, the project tempo must be adjusted to match the tempo of the audio file.

In type (B) situation, an audio file is being added to an existing project whose tempo has already been set. Therefore, the tempo of the audio region must be adjusted to match the project tempo.
When an audio file is imported into an existing project, why might it have to be time stretched?
If that tempo doesn't match the project tempo, the audio file has to be time stretched. [Unless it's an Apple Loop, audio files always play at their original tempos.]
How do you time stretch an audio or MIDI region?
1. Select the region
2. Local Arrange menu > Audio > Time Machine Algorithm > [choose one of three]
3. Place pointer over lower right corner and it turns into a Resize tool.
4. Option-drag to time stretch region to desired length.
Being that time stretching is a destructive operation, what does Logic do to the region begin stretched?
It makes a copy of the original audio file and appends a ".1" to its filename. You'll actually time stretch the copy, leaving the original file intact.
How do you bypass a Setting plug-in?
Option-click it
Which three region types will always follow the project's tempo map?
1. MIDI regions
2. Apple loops
3. audio regions set to follow tempo
How do you match the project tempo to an audio file's tempo?
1. Drag a cycle of the same number of bars as the audio file.

2. In the main menu,
Options > Tempo > Adjust Tempo using Region Length and Locators.
How do you insert a tempo change?
In the Global Tracks > Tempo, double-click above or below the tempo line.
