Preface New Features in Logic Express 7.2 This document describes features not covered in the Logic Express 7 manuals. It contains detailed information about the improvements and changes found in the Logic Express Updates that have been released since Logic Express 7. Important: The descriptions in this document supersede the relevant sections of the Logic Express 7 manuals! For late-breaking information about Logic Express 7.2, please refer to the Late-Breaking News document.
Logic Express 7.2 Features Overview This section provides a summary of the Logic Express 7.2 features. For more information on these features and their use, see the corresponding chapters in this document. Playback of compressed file formats Logic Express 7.2 allows the direct playback of compressed file formats, such as AAC. These files no longer need to be automatically converted when imported. For detailed information, see “Direct Playback of Compressed Audio Files” on page 23.
Key command changes The Logic Express 7.2 Update features the following key command changes:  Go to Song Start—New  Remove Movie—New  Save as Performance—New  Go to Selection End—New. This Sample Editor key command sets the SPL to the end of the selected audio file section. The Goto Selection key command has been renamed as Go to Selection Start. For a complete list of all key command changes since the Logic Express 7.0 release, please read about the “Key Command Enhancements” on page 15.
Enhanced AAC Sound Settings Window Logic Express 7.2 features an improved, unified AAC Sound Settings window that simplifies the creation of this compressed file type. For more information, see “Streamlined AAC Sound Settings Window” on page 33. Support for up to 32 mono outputs for Audio Units instruments Logic now supports up to 32 mono outputs for multi-channel Audio Units instruments. For further information, read about “Audio Units Multi-Channel Instrument Support” on page 83.
1 General Improvements 1 This chapter describes all general enhancements that have been made since Logic Express 7. These changes streamline and simplify the use and setup of Logic. They include:  Plug and play of audio interfaces  Interface enhancements  Preference and song setting enhancements Plug and Play of Audio Interfaces Logic Express supports plug and play for audio interfaces, making it possible to connect and switch on a new/additional audio interface while Logic is running.
Dialog Enhancements A number of changes have been made to the following Logic dialogs: Â Sample Editor: Audio File > Save Selection As, Audio File > Save a Copy As. Both dialogs allow you to set the desired sample rate, stereo conversion and dither type for the destination file. The dialogs also feature an “Add resulting files to Audio window” option. Some file dialogs feature additional file conversion settings.
Parameter Boxes All parameters that only have two states (on/off, for example) are enabled/disabled with checkboxes. Simply click on the box to activate (checked) or deactivate (unchecked) the parameter.
New Auto Hide Dock Preference The General pane of the Display preferences in Logic Express 7.2 offers the Auto Hide Dock option. Auto Hide Dock preference Activation of this preference automatically hides the Dock while Logic is running, maximizing onscreen space for Logic windows. To activate the Dock Auto Hide preference: 1 Choose Logic > Preferences. 2 Click the Display button. 3 Activate the Auto Hide checkbox in the Dock section of the General pane.
2 Editing Enhancements 2 This chapter outlines the editing enhancements made since Logic Express 7. These changes encompass a number of new or altered key commands, new track creation facilities and improved marker handling, among others. Key Command Enhancements The following section outlines all key command enhancements made since the release of Logic Express 7.
Key command Function/Explanation Project Settings Opens the Project Settings window. Clean Up Project Displays all unused audio files or EXS instruments in your project folder, allowing you to delete them. Consolidate Project Moves all files associated with a project into one folder. Rename Project Opens a dialog that allows you to rename your project. Save as Project Saves a song or project. If the open song isn’t already a project, the song is assigned project status.
Key command Function/Explanation Create Hyper Set For Current Events A Hyper Set is created, based on controller information that exists in the selected Region(s). Clear Hyper Set Removes all controller definitions from a Hyper Set. Track Mixer All Filter buttons can be switched on and off via key commands. Key command Function/Explanation Toggle MIDI Instruments Shows/Hides MIDI instrument channel strips. Toggle Audio Tracks Shows/Hides audio track channel strips.
Sample Editor The Sample Editor offers the new Go to Selection End key command, which moves the SPL to the end of the selection (within an audio file). The Goto Selection key command has been renamed as Go to Selection Start. New Key Command Warning In circumstances where an existing local key command combination is used while assigning a new global key command, the following warning message will appear: You have three options: Cancel, Replace, or OK. Â Cancel does not alter existing assignments.
Loop Length Editing The Loop feature of Logic 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 half of the Region. 2 Click-hold and drag the end of the Region to the desired length.
 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.
Newly created markers are automatically named “Marker ##”. The “##” value indicates their order of appearance in the timeline, which will be displayed in the Bar Ruler as “Marker 1,” “Marker 2” and so on. The number always refers to the actual order of all markers in the song, including renamed markers. To edit a marker name: 1 Double-click on the marker while holding down Control-Command. 2 A text entry field opens, allowing you to edit the marker’s name.
Select If you choose this option, you can use the Automation tool to rubber band any selection (of nodes) in the automation data. A click on a Region selects all currently visible automation events within the Region borders. Once an area of (or the entire) Region is selected, you can freely move the selection to the left or right. With Option pressed, you can copy the selection to a different location. Please note that both operations will delete all nodes in the destination area.
3 Working With Audio 3 Many audio editing facilities have been enhanced since the release of Logic Express 7. Logic Express 7.2 introduces direct playback of compressed audio files and split stereo file renaming enhancements, among others. Direct Playback of Compressed Audio Files Logic Express 7.2 allows you to directly play back the following compressed audio file formats: Â AAC Â Apple Lossless files These files are no longer automatically converted when imported into Logic.
The Project Manager can organize these compressed audio file types. The Audio File category in the Browse view now offers the Compressed subcategory. The Find mode Audio File filter also includes a new Compressed checkbox: Activate it to search for all compressed AAC and Apple Lossless audio files.
2 Enable the Follow Tempo option in the Region Parameter box. All audio files that follow the song tempo and first key signature are indicated by the following symbols in Logic: Note: Follow tempo is actually an audio file tempo operation, not a Region function, but was included in the Region parameter box for convenience. It is synchronized for all Regions that make use of the same audio file.
Faster Overview Creation The Overview Creation dialog features an additional option which accelerates overview creation. This makes overview creation as fast as the “foreground” overview creation of Logic 6 (at the cost of slowing down other operations, but not blocking user interaction completely). Logic remembers the state of the “Faster overview calculation” option. Renaming Split Stereo Files You can now independently rename disconnected stereo files.
4 Working in the Mixer Windows 4 Logic Express 7.2 allows you to switch between Channel Strip settings by sending MIDI program change messages. It also allows you to toggle the bypass status of Insert slots with one controller value. The following chapter outlines all mixing and bouncing enhancements made since the release of Logic Express 7.
2 Open the Channel Strip Settings menu by clicking the word Insert on any channel strip, then choose “Save as Performance”. 3 In the ensuing dialog, enter a Performance name, choose a program change number and click OK. You can also set the program change number by sending it from your MIDI controller. Note: By default, the dialog will suggest the lowest, unused program change number. An alert will advise you of any attempt to insert a program change number that is already assigned.
All saved Performance settings appear in the Performances folder of the Channel Strip Settings menu. Multiple Selection of Channel Strips The Multiple Selection of channel strips function (in the Mixer windows) has been enhanced: Clicking a channel background (without Shift held) also allows you to select further channels by dragging over them (in the background).
Automating the Bypass Status Logic Express 7.2 allows you to toggle the bypass status of Audio Object Insert slots with a single controller value: namely controller value 64. The addition of this feature results in the following behaviors for controllers 56 to 60: Â A value of 0 switches bypass off. Â Values 1 to 63 and 65 to 127 switch bypass on. Â Repeated use of value 64 switches between the two bypass states.
Note: ReWire is a system from Propellerhead Software that allows you to stream audio data between two audio applications in real time. You can use ReWire to stream audio data from Propellerhead‘s Reason software into Logic, for example. Further information about ReWire is found in the Logic Pro 7 Reference Manual. To use stereo ReWire Objects in Logic Pro 7.2: 1 Start Logic, then start your ReWire application. Logic displays the audio returns of ReWire-connected applications as Audio Object channels.
Hand Tool in Track Mixer and Arrange Channel Strip The Track Mixer Hand tool is used to move and copy plug-ins between channel strips. To move a plug-in between two Insert slots: 1 Click the Hand tool in the Track Mixer Toolbox. 2 Select the (source) plug-in label and drag it to the desired target slot. During the drag and drop operation, the potential destination is displayed as an orange rectangle (empty slot) or line (when placing an effect between two Insert slots—see below).
Bouncing Enhancements The Bounce facilites in Logic have been enhanced in the following areas since the release of Logic Express 7: Â AAC bounce options are now available in a single Sound Settings window. Â The Bounce dialog‘s Device menu allows you to choose between any recognized CD burners connected to your system. Â The default values for bounce start and end positions take a wider selection range into account.
 Show Advanced Settings: Activate this checkbox to show further AAC settings in the area below.  Quality (Sample Rate Converter): Sets the quality of the sample rate conversion. Reducing the quality accelerates the conversion process, but at the expense of audio quality. Keep this set to Best whenever possible.  Bit Rate Format: You have a choice of Constant or Variable Bit Rate: Variable Bit Rate (VBR) encoding compresses simpler passages more heavily than passages that are (more) harmonically rich.
5 Importing Files 5 The importation of MIDI file data has been improved since Logic Express 7. These enhancements make it easier to import event-based MIDI data into Logic Express. Importing MIDI Files Opening and importing MIDI files behaved in a similar fashion in earlier Logic versions. Both the Import and Open commands loaded all data (including global information, such as tempo events) into a new song.
To open a MIDI file: 1 Choose File > Open from the main menu bar (or use the Open key command), then select the desired MIDI file in the ensuing file selector box. If a song is loaded, a dialog will ask if you want to create a new environment or copy the current environment for the MIDI file. 2 Do one of the following: Â Click Copy to replicate the existing environment. The tracks of the MIDI file are automatically assigned to suitable instruments.
6 Control Surface Support 6 The extensive support for control surfaces has been further enhanced since the release of Logic Express 7. Direct support for a number of control surfaces has been added, and several key usability and assignment facilities have been improved. These include the track control bar and key repeat functions.
Working With the Track Control Bar When a control surface is connected to Logic Express 7.2, the Track Control Bar is displayed in the Arrange window. This bar indicates the tracks that are currently being accessed by your control surface. This bar is available for all control surface devices connected to your system. The Track Control Bar of each control surface can be assigned a different color. The bar color is set in the Device parameter box.
New Key Repeat Function Logic Express 7.2 provides updated control surface plug-ins that support the Key Repeat function (if useful and/or applicable to the device). When active, the key command function being triggered via a controller assignment is continuously executed for as long as the button or switch is held down. The length of time before Logic begins to repeat the assignment is determined by the Key Repeat Rate—set in the Mac OS X Keyboard & Mouse preferences.
 All buttons (push buttons, including Enter/default and Cancel, as well as checkboxes and radio buttons, but not pop-up buttons) are shown in the display’s lower row (if applicable to the device). Pressing a control surface button below the display triggers the appropriate button/function in the dialog, where relevant. Following use of the Enter/Cancel button on the control surface (or with the mouse), the dialog will disappear, and all controls and displays will return to their previous state/mode.
7 Using Apple Loops 7 The support of Apple Loops in Logic Express brings a range of flexible options to your music-making palette. This chapter covers their use in Logic Express, information on Apple Loop creation and further material that will aid you in making the most of the facilities available. Logic Express ships with a number of Apple Loops, as does GarageBand. Apple Loops are AIFF format audio files that contain PCM audio data.
Green and blue Apple Loops can be added to audio tracks. They look like normal Audio Regions, but can be easily identified by the Apple Loop symbol in the upper right corner. They follow the song key and tempo. Stereo Apple Loop symbol Mono Apple Loop symbol Apple Loops that feature the green icon can also be placed on Audio Instrument and MIDI tracks. On such tracks, these files can be edited just like other MIDI Regions, including individual note editing.
Adding Apple Loops There are several ways to add Apple Loop files to your Logic song. Logic Express offers a special Loop Browser that enables you to search for Apple Loops, using key words for instrument, genre, mood, and other descriptors. You can also import Apple Loops in the same way as audio files. To add an Apple Loop to your arrangement, do one of the following, m Open the Loop Browser by choosing Audio > Loop Browser (or use the Loop Browser key command).
Working With the Loop Browser The Loop Browser is designed to make finding Apple Loops an intuitive and fast process. You can search for loops by using keywords, perform text searches, preview loops, view information about loops, and limit the display to loops from a specific Jam Pack or loop library. To open the Loop Browser, do one of the following: m Choose Audio > Loop Browser. m Use the Loop Browser key command.
The View buttons at the top left switch between three view types. The first button from the left, featuring the three rectangles, switches to a standard Mac OS X column file menu that is hierarchically separated into All, By Genres, By Instruments, By Moods, and Favorites search criteria. The second button from the left (featuring the note icon) switches to the “normal” Matrix view mode, showing musically-related categories.
The Scale pull-down menu offers Any, Minor, Major, Neither and Good For Both options. Use of these options limits the search for Apple Loops to the selected Scale type, within the chosen category. As an example, if Country, Acoustic and Relaxed categories were selected, you would be presented with twenty or so files that matched your choices.
Adding Apple Loops to the Loop Browser Logic Express must index Apple Loops before they are shown in the Loop Browser. Loops can reside in any directory, but you need to tell Logic Express where to find them. To add Apple Loops to the Loop Browser: 1 Open a Finder window alongside Logic Express. 2 Navigate to the folder that contains the Apple Loops. 3 Select the Apple Loops in the folder and drag them into the Loop Browser. The loops are added to the Apple Loops library and indexed.
Working With Favorites The Fav (Favorites) column in the list at the bottom of the Loop Browser offers a checkbox for every displayed loop. Simply check this box to add the loop to the Favorites category. This facility is ideal for compiling a collection of Apple Loops that you use regularly. As a producer of dance-floor music, you may often construct songs by starting with drum loops.
Note: The Apple Loops Utility does not allow you to create SIALs. Which tool to use, and when to use it? As mentioned above, Logic Express offers Apple Loops creation facilities, and the separate Apple Loops Utility also allows you to construct your own Apple Loops. You have a fairly simple decision path to follow: Â If you want to create an Apple Loop from an audio file that matches the song tempo, use the Apple Loop creation utilities available in Logic Express.
 Set the file type, which can be One-shot or Looped. If the length of the audio file is not precisely trimmed to contain a number of whole bars, One-shot is selected automatically, and the file type buttons are dimmed. Note: One-shots do not follow the song tempo and key. This is useful if you want to add discrete, non-musical sounds (such as sound effects) to the loop library, which should not be altered by the tempo and key properties.
If you want to create a looped Apple Loop from an audio file that does not match the song tempo, you should use the Apple Loops Utility. The Apple Loops Utility allows you to define the intended length of the loop, regardless of the song tempo, by setting the Number of Beats and Time Signature tag manually. Please note that the utility only works with Audio Regions—not with MIDI regions on Audio Instrument tracks.
You can use one of the following options to ensure that loops created from Audio Instrument Regions will sound the same as the original Regions: Â Drag your SIAL (the original of which was assigned to bus sends) to an audio track instead of an Audio Instrument track. When you create an Audio Instrument loop, the audio file that is rendered will include any bus processing. This will sound identical to the original.
The Apple Loops Utility Interface The Apple Loops Utility window consists of the Tags and Transients panes. The bottom of the window includes a set of playback controls and file management buttons. The Apple Loops Utility also includes an Assets drawer, located to the right of the main window, where you can manage open files.
Tags Pane The Tags pane is divided into four areas. In three of the sections, you edit different types of tags. In the fourth area, you view information (that cannot be edited in the Apple Loops Utility), such as the length and location of the file. The more metadata (tag) information you include with your files, the more accurate your searches will be in the Loop Browser.
Provided that the audio file matches the song tempo, and that its length fits a whole number of beats (or you entered the correct length in the “Open Audio File in Apple Loops Utility” dialog), the Apple Loops Utility sets the correct default value for the Number of Beats field. Note: If you open an audio file directly in the Apple Loops Utility this information is not available. In this situation, the Apple Loops Utility uses different assumptions to set the Number of Beats value.
The Scale Type tag identifies the file’s scale type. It only serves as a search tag and has no effect on the sound of the loop. Changing a loop’s Scale Type does not affect the scale of the loop. Again, this defaults to the information Logic Express provides, courtesy of the Signature track. Music uses various scale types. The main types are the major and minor scales. Musical loops in the same key (with the same root note) may not sound appropriate when played together, if their scale type differs.
Descriptors The Loop Browser in Logic Express allows you to search for files using descriptors. Descriptors are complementary pairs of keywords that describe the musical mood or character of the file. Each pair of keywords offers a row of radio buttons, allowing you to choose either one keyword from the pair, or neither keyword. Tagging Files To tag a file, select it in the Assets drawer, then edit the file’s tags in the Tags tab. You can change the tags of multiple files at the same time.
The Transients pane contains a large waveform display, a beat ruler and a horizontal scroll bar. Markers indicate the position of transients in the file. Typically, transients correspond to the (vertically) widest parts of a sound’s waveform (the peaks in the waveform, in other words). The Transient Division pop-up menu and the Sensitivity slider determine the placement of transient markers in a loop. The Transient Division menu sets the beat value used by the Apple Loops Utility for transient detection.
You should also keep the following guidelines in mind: Â Each transient marker in the audio file should be labelled by a transient marker in the Apple Loops Utility. You should also add a transient marker at all points of musical significance, including the beginning and end of notes, pitch bends or glissandos. Â During playback, Logic Express speeds up or slows down the tempo of loop areas without transient markers.
Playback and File Management Controls The bottom of the Apple Loops Utility window contains a set of playback controls, allowing you to audition the selected file. These controls do not affect the file’s tags. Go to Beginning button Play button Stop button Volume slider Key menu       Tempo slider Go to Beginning button: Starts playback from the beginning of the selected file. Play button: Plays back the selected file. Stop button: Stops playback of the selected file.
2 Choose the Render to Apple Loop option in the Fix menu of the ensuing ReCycle File Import dialog. The ReCycle loop is converted to an Apple Loop (the slice points are converted to transient positions) and copied to the ~/Library/Audio/Apple Loops/User Loops/Single Files folder. The Apple Loop is added to your Logic song. Global Tracks and Apple Loops You can use the Global tracks to change global events such as tempo, time signature and key during a song.
Converting Apple Loops to Audio Files When you convert an Apple Loop into an audio file, the resulting file may not play at the song’s current tempo and key settings. Rather, the new audio file will play at the original tempo and key of the Apple Loop. This happens when you select an Apple Loop and choose Audio > Convert Regions to New Audio Files from the Arrange menu, and change the File Format parameter in the ensuing window from “Original file type” to either “Wave” or “SDII”.
Note: If a new Apple Loop is created, it will need to be indexed to make it visible in the Loop Browser. Loops can reside in any directory, but you need to tell Logic Express where to find them.
8 Updated File Paths 8 The location of all files (preferences, plug-in settings and so on) associated with Logic Express have changed. Unlike earlier 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).
Plug-in Settings Logic Express scans for a folder named after the plug-in (“PlugInName/”) in the following folders, and order: Â ~/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. The “Save Setting as” command defaults to this level. “Save Setting” only works on settings located at this top level (otherwise a “Save Setting as” is performed).
Channel Strip Settings Logic Express scans for a folder named “Channel Strip Settings” in the following folders, and order: Â ~/Library/Application Support/Logic User-defined or edited Channel Strip settings are stored here. Â /Library/Application Support/Logic Factory settings are always stored here. Logic Express also scans the following folder path for Track and Instrument Audio Objects: /Library/Application Support/GarageBand/Instrument Library/Track Settings.
User Icons Logic Express scans for user-definable track icons in the following folder: ~/Library/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. Control Surface Plug-ins Control Surface plug-ins are installed (and searched for) in the application bundle.
9 Plug-in Enhancements 9 The following chapter outlines the plug-in enhancements that have been made since Logic Express 7, superseding the information in the Logic Express 7 Plug-in Reference.
Note: Logic Express automatically quits before the Logic AU Manager is launched. Logic will automatically restart after you quit the Logic AU Manager. 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.
Working With Plug-in Delay Compensation Logic Express includes plug-in delay compensation for instruments, tracks, busses, auxes, outputs and ReWire Objects.
As an example: Imagine a simple song with a few bass, guitar, vocal, and drum tracks. The bass track is played through an Audio Object that contains a plug-in that introduces a latency of 100 ms. All guitar tracks are routed to a Bus Object that contains several inserted plug-ins. The combined latency introduced by these plug-ins is 300 milliseconds (ms). The vocals are routed through another Bus Object that has a set of plug-ins that introduce 150 ms of latency.
Dealing With Latency Issues To avoid these potential pitfalls, try to complete any audio and audio instrument recording before inserting latency-inducing plug-ins. If you find it necessary to record an audio instrument or audio track after setting up a latency-inducing signal routing, the following procedure will help you to get around any possible problems.
If you are recording audio, another strategy would be to disable the Software Monitoring checkbox in the Logic > Preferences > Audio > Drivers pane. This would necessitate monitoring your recording via an external mixer. When Logic is not providing software monitoring of incoming audio, it can correctly position audio recordings—even when full delay compensation is active. Obviously, you can’t use external monitoring when recording audio instruments.
EXSP24 mkII The following information supplements the EXSP24 mkII section in the Logic Express 7 Plug-In Reference. Vel Offset parameter The Vel Offset parameter—found towards the top left of the EXSP24mkII GUI—offsets the incoming MIDI note velocity value by ±127. This limits or expands the dynamic response of the EXSP24 mkII to incoming note events.
GarageBand Instruments Two additional GarageBand 2 instruments are included in Logic Express. These are the sample-based Hybrid Basic and Hybrid Morph synthesizers. Both synthesizers are limited to a few powerful, but easy to use parameters, outside of the common ADSR, cutoff and resonance options. Experiment with these controls to discover how simple it is to create spectacular sounds. Of note are the Wave pop-up menus, which allow you to choose the sample set used to generate the basic synthesizer sound.
In the Hybrid Basic synthesizer, you can use the Wheel to Vibrato and Wheel to Cutoff sliders to determine the parameters controlled by the modulation wheel. Bass Amp The Bass Amp plug-in simulates the sound of several famous bass amplifiers. You can process bass guitar signals directly within Logic and reproduce the sound of highquality bass guitar amplification systems. You can also use the Bass Amp for experimental sound design.
 Top Class DI Warm: Famous DI box simulation, well suited for reggae and pop recordings. Mids, in the broad frequency range between 500 and 5000 Hz, are deemphasized.  Top Class DI Deep: Based on the Top Class DI Warm model, this setting is well suited for funk and fusion: its mid frequency range is strongest around 700 Hz.  Top Class DI Mid: Based on the Top Class DI Warm model, this setting does not emphasize any frequencies, but features a more or less linear frequency range.
The Ducker plug-in provides a simple means of performing this process. It can even reduce the music level before the speaker starts (but this introduces a small amount of latency). To use the Ducker plug-in: 1 Insert the Ducker plug-in into an Audio Output or Bus Object. 2 Assign all track outputs that are supposed to “duck” (dynamically lower the volume of the mix) to a bus. 3 Select the buss that carries the ducking (vocal) signal in the Side Chain menu of the Ducker plug-in.
New Speech Enhancer Plug-in Logic Express 7.2 includes the new Speech Enhancer plug-in. This plug-in is designed to improve speech recordings made with your computer’s internal microphone (if applicable). It combines denoising, advanced microphone frequency remodeling and multiband compression. The plug-in offers the following controls: Â Denoise: The value of this slider determines your estimation of the noise floor in your recording, and therefore, how much noise should be eliminated.
The Enhance Timing plug-in is designed to “tighten up” loose playing (of recorded audio) in a production. It can be used on a variety of material, and works in realtime. Obviously, this type of real-time quantization has some limitations. It will not work well on recordings of performances that have been played too far off the beat. The same is true for very complex, layered drum tracks.
Enhance Pitch Effect Logic Express includes the Enhance Pitch effect, that non-destructively corrects the tuning of audio recordings. The Response slider determines how quickly the audio recording reaches the corrected destination pitch. If the Response is too slow, the pitch of the output signal won’t change quickly enough. The Response of pitch changes is indicated in milliseconds. The optimum setting for this parameter depends on the tempo, vibrato, and quality of the original performance.
Audio Units Multi-Channel Instrument Support Logic Express 7.2 supports up to 32 mono outputs from multi-output Audio Units instruments (previous Logic versions supported 16 mono channels). To access the individual outputs of an Audio Instrument: m Click the Instrument slot of the Audio Instrument Object and choose the desired Audio Units instrument from the Plug-in menu’s Multi Channel submenu.
Appendix Corrections to Logic Express 7 Documentation 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. You may freeze such tracks.
