Sudden Motion Sensor: Advanced Tips

Thu, 20 Jan 2005 11:58:42 -0600

Beginning with the PowerBook G4 (12-inch 1.5GHz), PowerBook G4 (15-inch 1.67/1.5GHz), and PowerBook G4 (17-inch 1.67GHz), PowerBook G4 computers feature a Sudden Motion Sensor.

Apple has adjusted this feature carefully to provide the best balance between protecting the hard drive and preventing unwanted activation of the Sudden Motion Sensor. Most PowerBook G4 owners will never need to turn this feature off, and Apple suggests that you not modify the settings unless absolutely necessary.

In some environments, such as live concert halls, recording studios, or dance clubs, external vibrations may be major enough to cause the module to unexpectedly park the hard

Logic: CoreAudio System Overload Messages

Thu, 11 Jan 2007 08:38:45 -0600

When you work with Logic, you may occasionally see this error message:

System Overload. The audio engine was not able to process all required data in time.

The following is a discussion of what this message means, and some strategies to help avoid it.

When you work with audio in Logic, several areas of your computer are put to work. When Logic records and plays back audio tracks CPU power and hard disk I/O capacity is needed. Audio DSP effects and software instruments require CPU power and RAM. No computer has infinite capacity in any of these areas,

Logic Pro: How to use the XSKey Updater

Tue, 12 Jul 2005 13:20:22 -0500

Logic Pro and WaveBurner Pro require you to attach a USB device, called an XSKey, to your computer to use the applications. The XSKey is programmed to know if you're authorized to run a particular version of the software. However, sometimes the contents of its built-in memory may get inadvertently changed, leaving you unable to use the software.

The XSKey Updater, an easy-to-use tool that can analyze your XSKey, can correct these issues in most cases. Please note that if your XSKey is physically or electronically damaged, the XSKey Updater will not work.

You can download the XSKey

Logic Pro and Logic Express: No sound with Mac Pro

Mon, 4 Jun 2007 22:36:55 -0500

Issue or symptom

Logic does not output sound when you use the built-in audio hardware on the Mac Pro.

Products affected

Logic Pro
Logic Express

Solution

Versions of Logic prior to 7.2.3 are not compatible with the built-in audio hardware on the Mac Pro — they do not allow the outputs to be assigned in Logic's Audio > Audio Hardware & Drivers window.

Logic Pro and Logic Express 7.2.3 provides access to all three outputs available on the Mac Pro:

Built-in Line Output (the line out

Some software DVDs may fail to mount in SuperDrives

Thu, 24 Feb 2005 05:38:40 -0600

Some SuperDrive-equipped Power Mac G5, Power Mac G5 (June 2004), and eMac (USB 2.0) computers may not consistently mount all of the DVD discs included in some Apple software packages. Sometimes the DVD-ROM media will mount; other times it will be rejected (the optical drive will eject the disc with no error message).

The issue does not consistently affect all of the included media, and may occasionally be seen with non-Apple software products.

Some of the discs that may cause this issue include the following Apple retail software (released since May 2004):

Final Cut Pro HD
Production Suite
Logic 7

Mac OS X 10.4: How to change an application's language to be different from the primary system language

Tue, 26 Jul 2005 15:07:52 -0500

In Mac OS X "Tiger" versions 10.4 to 10.4.2, you can't deselect an application's primary system language in the Info window (the window you see after selecting an application in the Finder and choosing File > Get Info). For example, if you have German set as your computer's primary system language, the "German" checkbox in the Languages section of the Info window will be dimmed.

To resolve this issue, update to version 10.4.3 or later. After updating, you'll be able to deselect the primary system language as long as at least one other language box remains checked. When only

Logic Pro: Using multiple outputs with Ultrabeat

Mon, 14 Feb 2005 11:16:10 -0600
Logic Pro can route audio from various software instruments to different destinations. This allows you to process different voices of the same instrument with independent DSP plug-ins, or to route different streams of audio to different outputs on your audio hardware.
Logic's integrated drum machine, Ultrabeat, is one instrument that can greatly benefit from this feature, allowing you to process each drum voice (kick drum, snare, toms, cymbals, and other percussive sounds) within a kit individually. Here's how to set up Ultrabeat to use multiple outs:

Logic 7: Changes to preference location, file name, and troubleshooting practices

Mon, 4 Jun 2007 21:51:01 -0500

Logic Pro 7 and Logic Express 7 both have different preference file names, compared to earlier versions. Additionally, these preferences are now set apart in a Logic subfolder of your Preferences folder. The new preference files are stored as follows:

Logic Pro 7: ~/Library/Preferences/Logic/com.apple.logic.pro
Logic Express 7: ~/Library/Preferences/Logic/com.apple.logic.express

If Logic 7 detects that the current preference file is missing (if you moved it for troubleshooting, for example), it will seek and load an older preference file if one exists on your computer. If you have an older version of Logic installed, its preference file is stored here:

Logic Pro 7: How to export songs for earlier versions of Logic

Mon, 4 Jun 2007 21:05:20 -0500

Any song¹ that you create in Logic Pro 7 can be opened in Logic Pro 6.4.3 but not in earlier versions. However, you can export songs that will be compatible with versions as early as Logic 4.8 if you have Logic Pro 6.4.3.

To do this, open a song in Logic Pro 6.4.3 and save it from there to use in Logic 6. Logic Pro 6.4.3 also allows you to export a song in Logic 4.8 format for use in Logic 5 and Logic 4.8:

Exporting to Apple Lossless from Logic 7

Fri, 10 Dec 2004 05:59:18 -0600
Logic Pro 7 and Logic Express 7 cannot export files directly to Apple Lossless. Instead, you'll need to first export your project to AIFF, and then convert the AIFF file to Apple Lossless using iTunes.

Export your project as an AIFF file from Logic Pro 7 or Logic Express 7.
Open the AIFF file in iTunes (version 4.6 or later).
From the iTunes menu, choose Preferences.
Click the Importing tab.
From the Import Using pop-up menu, choose Apple Lossless Encoder.
Click OK.
Select the AIFF file in iTunes

Logic Pro 7: "Error while Trying to Synchronize Audio and MIDI" with 48kHz

Wed, 13 Oct 2004 13:10:48 -0500
After switching the sample rate for DAE to 48kHz, you get this message each time the playback is started:
"Error while Trying to Synchronize Audio and MIDI. Sample Rate 48000 recognized"
This happens because the sample rate was changed to 48kHz within the Digidesign Hardware Setup panel in the local options menu of the Audio window. This changes the sample rate of the TDM hardware but does not change the sample rate in Logic Pro as the front-end application. So, Logic Pro still expects a sample rate of 44.1kHz while the audio hardware is running at 48kHz.
To prevent

Logic Pro/Express 7: Core Audio driver cannot be selected

Wed, 16 Mar 2005 13:48:53 -0600

In some situations, the Driver selection menu and other settings in the Core Audio preference pane of Logic Preferences (from the Logic Pro or Logic Express menu, choose Preferences, then Audio, click the Drivers tab, then click the Core Audio tab) may appear dimmed (unavailable).

This happens if Core Audio is disabled, which can occur after you remove your Logic preferences or install Logic on a fresh system without running the Setup Assistant.

To select a driver:

Logic Pro and Logic Express 7: How to create an Autoload Song template file

Fri, 11 Feb 2005 14:15:24 -0600
In earlier versions of Logic, if you saved a file named Autoload in the same directory as the Logic application, that file would be used as the default song template whenever you launched Logic or created a new song. You can still use this method in Logic Pro and Logic Express 7, but the location for storing your Autoload template has changed.
With Logic's expanded Templates feature, you can create an unlimited number of templates. To create an Autoload Song:

Open an existing song file that you'd like to use as the default template, or create a new one and configure

Logic Pro/Express: How to send audio to Soundtrack Pro

Tue, 30 Aug 2005 21:19:31 -0500

Soundtrack Pro can be a very useful addition to your Logic Pro or Logic Express workflow. While Logic doesn't have a dedicated feature that sends audio directly to Soundtrack Pro, you can edit audio from Logic projects in Soundtrack Pro by way of a Logic key command that opens an external sample editor, which you can set to open Soundtrack Pro. Here's how to do this.

Assign the key command first

By default, Logic doesn't have a key assigned to this command, so the first step is to assign one:

Logic Pro 7: Using effect plug-ins with MIDI input

Wed, 6 Oct 2004 10:35:03 -0500
Learn how to use audio effect plug-ins which have an additional MIDI input, such as Antares Auto-Tune, vocoder plug-ins, or Logic Pro's EVOC20.
Audio tracks don't accept MIDI input, which is why an effect plug-in that has been inserted in an Audio track, Bus, or Aux channel does not respond to MIDI input. Only Audio Instrument tracks accept MIDI input.
To use the MIDI input of these plug-ins, insert the plug-in into the first insert (the instrument insert) of an Audio Instrument track, just as with any other software instrument.

Logic Pro/Express 7.1: Adding loops to the Loop Browser

Wed, 6 Apr 2005 12:33:21 -0500

Logic Pro and Logic Express come with a large number of Apple Loops for you to use in your music compositions, but you can also turn any audio region—up to one minute in length—into an Apple Loop, or add loops to the Loop Browser from the Finder.

To turn a region in the Arrange window into an Apple Loop, simply highlight the region and choose Region > Add to Apple Loops Library. In the resulting dialog, you can assign search tags to the loop for better sorting. The loop file will be stored at ~/Library/Audio/Apple Loops/User Loops/SingleFiles.

Logic Pro 7: Latency when playing software instruments

Wed, 6 Oct 2004 06:11:54 -0500
When playing a software instrument from the MIDI keyboard, you might get undesired delay between actuation of the instrument and the resulting sound from the computer. There are several reasons this might happen.
The audio buffer size is set to a high value
The audio data produced by a software instrument is temporarily stored in a buffer. This audio buffer must be completely filled before it is transferred the sound card and your speakers. The larger the buffer, the longer it takes until you actually hear a sound after pressing a key on your MIDI keyboard.

Logic Pro 7: Using the External Instrument

Wed, 9 Mar 2005 15:33:13 -0600
One of the little known but most useful new features in Logic Pro 7 is the External Instrument. This is a special instrument plug-in that allows you to route MIDI information to an external MIDI hardware module and, utilizing your audio interface, feed that module's audio output directly into Logic. This allows you to treat the MIDI module like a software audio instrument in Logic; you can add plug-ins, bounce it as part of your mix, and so on.
Here's how to set up an External Instrument track for your MIDI device:

Logic Pro/Express: Digital input not available

Tue, 21 Jun 2005 15:02:01 -0500

Logic Pro and Logic Express cannot access the digital input on certain computers. The affected systems will list the digital input as a separate device in Audio MIDI Setup. To check your system, follow these steps:

Open Audio MIDI Setup (located in /Applications/Utilities).

Click the Audio Devices tab.

Open the Default Input pop-up menu.

If your system shows more than one built-in input source, it will be affected by this issue.

Logic cannot access devices that offer only an input, and therefore cannot use the digital input. On systems with Mac OS X 10.4 or later, you can work

Logic Pro: Using multiple outputs with EXS24

Tue, 15 Feb 2005 13:01:39 -0600
Logic Pro can route audio from various software instruments to different destinations. This allows you to process different voices of the same instrument with independent DSP plug-ins, or to route different streams of audio to different outputs on your audio hardware.
The Logic Pro integrated software sampler, EXS24, is one instrument that can greatly benefit from this feature, allowing you to process sampler instrument groups individually. Here's how to set up EXS24 to use multiple outs:

Logic Pro 7.1: Follow Tempo setting changes without explanation

Tue, 12 Apr 2005 09:32:32 -0500

In some situations, regions that you haven't explicitly set to "Follow Tempo" will have this feature enabled. In other cases, regions that had been previously enabled to Follow Tempo are no longer enabled.

Although the Follow Tempo parameter for elastic audio can be enabled and disabled in the Region Parameter box, it's actually a property of the audio file. This means that if you enable Follow Tempo for a region, all other regions derived from the same audio file will also have Follow Tempo enabled. Likewise, if you disable Follow Tempo for a region, all other regions derived from the same

Logic: You can mix PowerPC and Intel-based systems in Logic Node setups

Sun, 12 Mar 2006 22:00:00 -0600

When configuring a group of computers as a Logic Node setup, it does not matter whether the master system and nodes use the same processor architecture. A PowerPC-based system running Logic Pro may connect to any combination of nodes running on PowerPC and Intel processors (the nodes must not all be the same). Likewise, an Intel-based system running Logic Pro may connect to nodes running on either processor architecture.

However, you must be sure that all nodes are running the same version Logic as the master, such as 7.2.0.

Logic Pro 7.2 not compatible with ProTools 6

Wed, 1 Feb 2006 13:10:09 -0600

Logic Pro 7.2 does not work under DAE/TDM with ProTools 6; DAE/TDM stops working after upgrading to Logic Pro 7.2.

For technical reasons, you can't run DAE/TDM with Logic Pro 7.2 and ProTools 6. If you are running a ProTools HD or HD Accel system, upgrading to ProTools HD 7 will resolve the issue. If you have earlier ProTools hardware that does not work with ProTools HD 7, then you will need to reinstall Logic Pro 7.1 from the original disc and use that version with DAE/TDM.

Before reinstalling, you need to delete the file /Library/Receipts/Logic Pro.pkg. You might also want

Logic Pro/Express: Plug-ins from old songs not available

Tue, 15 Mar 2005 20:32:11 -0600

When you load an old song into Logic Pro or Logic Express, sometimes the plug-ins won't appear on the inserts or if they do, they appear crossed out with a diagonal line. This happens when you load a song that was created with a different type of audio driver (for example, you created the song in Mac OS 9 with an ASIO driver). Logic will often offer to automatically convert the song to Core Audio, but here are some situations where this will not occur:

The Universal Track Mode setting for the current audio driver does not match the setting

The update is rounded out by a host of optimizations and refinements that significantly improve the performance and stability of both Logic Pro and the included,

Logic Pro 7: Audio file not found when loading GarageBand instrument

Wed, 18 Jan 2006 16:16:35 -0600

On a custom installation of Logic Pro, loading certain GarageBand instruments may invoke an alert message that says some audio files can't be found.
This can happen if you do not select the option for Logic Pro Bonus Sound Library or GarageBand 2 Sound Library. Rerun the Logic Pro Installer, and select both of those options this time.

Logic Pro/Express 7: Converted Apple Loops don't play at song's tempo or key

Mon, 4 Jun 2007 22:15:49 -0500

When an Apple Loop is converted into an audio file, the resulting file may not play at the song's current tempo and key settings. Instead, the new audio file will play at the original Apple Loop's tempo and key.

This happens when you select an Apple Loop region and choose Audio > Convert Regions to New Audio Files from the Arrange window menu and you change the "file format" parameter in the resulting dialog window from "Original file type" to either Wave or SDII. This creates a copy of the original Apple Loop file, but without the

Logic Pro 7: Ultrabeat, EXS24 or Audio Unit instrument not triggered by virtual keyboard

Tue, 5 Dec 2006 09:54:30 -0600

Under certain circumstances, clicking the virtual keyboard in the Ultrabeat, EXS24 or Audio Unit instrument interface won't produce any sound. In this situation, the virtual keyboard in the Matrix window also fails to produce sound.

This issue only occurs when using multi-channel instances of instrument plug-ins on sounds that are assigned to outputs other than Main. If this happens, put Logic into play. Another solution is to play a MIDI note into the instrument, either from an external MIDI controller or the Caps Lock Keyboard in Logic, to resolve the issue.

This document will be updated as more information becomes available.

Logic Pro 7: Keyboard shortcuts don't work in floating windows

Wed, 6 Oct 2004 09:01:57 -0500
Logic lets you open any window as a floating window. These windows will stay on top of all other windows, regardless of the currently active window, and they don't accept any keyboard shortcuts. Tip: You can open a window as a floating window by holding down the Option key while choosing the window type from the Window menu.
Floating windows are normally used as informational windows which don't get covered by selecting another one. This can be useful for an Event List, an Environment, or a Mixer window, for example.
When a window is opened as as floating window, it does

Logic Pro 7: Set song folder permissions to read and write

Tue, 19 Oct 2004 11:33:48 -0500
When loading a GarageBand song, Logic quits unexpectedly. This can happen because the song is inside a folder that has permissions set to read only.
To prevent this, set the folder to read-and-write permissions.
This issue will be resolved when you upgrade to Logic 7.1. If the folder containing the GarageBand song is read only, Logic will display a dialog box instead of quitting. You will still need to to set the folder to read and write before opening the song in Logic.

How to identify audio file types and formats of regions in Logic

Wed, 12 Dec 2007 23:58:32 -0600

Logic Pro/Express supports several audio file types and formats. These fall into three general types:

PCM audio files (such as AIFF, WAV and SD2).

Logic Pro, Logic Express: Instrument not triggered as expected

Mon, 14 Feb 2005 11:28:15 -0600
Sometimes you won't be able to trigger an instrument on an Audio Instrument or MIDI track as expected. This can happen if you inadvertently disable the Record-Enable button on the selected track. (Normally, a track's Record-Enable button will be enabled when you select the track.)
In order to monitor Audio Unit instruments, MIDI instruments, or incoming signals, this button must be turned on. When turned on, the button will be red.
When the button is turned off (it appears gray) on a selected Audio Instrument track, then incoming MIDI from your controller will not be able to trigger the instrument. You

Logic Pro/Express 7: Undo command unavailable after using Quantize Engine

Mon, 5 Dec 2005 19:11:39 -0600

After you quantize audio in the Sample Edit window by selecting Factory > Quantize Engine, Undo becomes unavailable in the Edit menu.

For technical reasons, Undo is not possible for audio quantize. Before using the Quantize Engine, create a backup of the audio file by choosing Audio File > Create Backup. If you change your mind after quantizing, choose Audio File > Revert to Backup.

Logic Pro, Logic Express: Error -40 when bouncing a session or freezing a track

Mon, 14 Feb 2005 15:14:16 -0600
Sometimes when you try to freeze a track or bounce a session in Logic, a dialog appears with this alert message:
Attempt to position before start of file. Result code = -40

Logic has a maximum audio file size of 2 GB when freezing tracks or bouncing sessions. If the file to be created by the bounce or freeze operation will exceed that size, you will get this error message. In practical terms, this will only occur with very long sessions or tracks.
The actual time limit is determined by the bit depth and sample rate in use. Frozen tracks are always stored

Logic Pro 7: Nodes could not be found or failed to connect

Wed, 6 Oct 2004 10:26:44 -0500
Even though the computers are switched on and connected to gigabit Ethernet with the Logic Node application running, some Logic Nodes may not be found on the network.
When starting Logic Pro or relaunching the audio driver, you get one of these messages:

"The following selected node failed to connect: nodename" followed by the node name, or
"None of the selected Nodes could be found on the network."

There are several possible causes for this, so you need to review each of the following to determine which affects your configuration.

Logic Pro 7: Instruments open up in Controls view after double-clicking

Thu, 11 Nov 2004 08:30:07 -0600
When double-clicking an instrument in the Input slot, the plug-in opens in the Controls view instead of the Editor view.
This can happen after dragging a software instrument loop (e.g. "70s ballad drums") from the Loop Browser onto an Audio Instrument track.
When this happens, switch to Editor view manually via the Editor menu at the top of the plug-in window.

Logic Pro versions earlier than 7.2 are not compatible with Pro Tools 7

Thu, 27 Oct 2005 22:00:00 -0500

Pro Tools version 7 contains significant changes to the Digidesign Audio Engine that make it incompatible with current versions of Logic Pro 7 using TDM. If you plan to use Logic Pro 7 with your TDM system, it is strongly recommended that you continue to use Pro Tools version 6.9.x.
To use Pro Tools 7 on the same system as Logic Pro, it would be necessary to create a separate startup partition, maintaining Pro Tools 6.9.x on one partition for use with Logic Pro, and installing Pro Tools 7 on the other.

Logic Pro 7: "XSKey driver too old!" message during launch

Thu, 21 Oct 2004 17:36:34 -0500
Symptom
When you try to open Logic Pro 7, you get a message that the XSKey driver is too old and has to be updated.
This happens only on systems which have had Logic 5 installed but not Logic 6. In this case, the XSKey driver cannot be updated by the Logic 7 installer.

Products affected

Logic Pro 7.0.0
Solution
Update the XSKey driver to resolve the issue. Follow these steps:

Download the installer.
Run the XSKey.pkg Installer.
Restart your computer when the installation is complete.

Logic Pro 7: No audio recording when using the "tape" icon

Fri, 22 Oct 2004 12:46:20 -0500
When the tape recorder icon is used as symbol on an audio track in the arrange window, audio cannot be recorded.
To prevent this, do not use the tape icon on an audio track. Using a different symbol will resolve the issue.

Additional information
MIDI tracks that have the tape icon and are located in first position at the upper edge of the arrange window are reserved for arming tracks on external tape recorders (ADAT machines or similar) over MMC.
The record ready switch of these tracks will in this case toggle record ready for the external tape recorder

Logic Pro 7: No format change for Freeze files

Fri, 3 Dec 2004 12:04:37 -0600
The Logic Pro 7 Reference Manual misleadingly states that the Freeze file format can be changed to 16 or 24-bit in Preferences > Audio. This information is no longer true for Logic 7.
If you used the Freeze function for exporting audio tracks in Logic 6, you can now use the superior feature of "Export Track as Audio File."

Choose File > Export > Track As Audio File or Export All Tracks As Audio Files.

This opens a file selector which allows to set the bit depth and audio file format. The first

Logic Express 7: Audio tracks won't record as expected in Cycle Record

Wed, 8 Dec 2004 06:39:44 -0600
The "Auto Create Tracks in Cycle Record" option does not work with audio recordings in Logic Express 7. Logic Express supports this option with MIDI tracks only. Although you can activate the option, audio will only be recorded during the first cycle. With MIDI recordings, the tracks are created as expected.
Logic Pro 7 supports the recording of audio tracks with this feature.

Logic Pro/Express, Soundtrack, Soundtrack Pro: Plug-in window text not localized

Thu, 19 May 2005 14:31:07 -0500

The text displayed in Logic Pro, Logic Express, Soundtrack, and Soundtrack Pro plug-in windows is always in English, no matter what language you selected.

For technical reasons, the text found in the various interface elements of plug-ins is always in English. Many of the terms derive from universal audio vocabulary that would not make sense in other languages.

Logic does not recognize REX files

Mon, 19 Jun 2006 14:29:42 -0500

Logic does not recognize ReCycle (REX) files if the required library is not installed.

Products affected

Logic Pro 7: Volume fader does not control the recording level

Thu, 21 Oct 2004 12:08:57 -0500
The volume fader does not change the recording level when an audio track is armed for recording. Logic always records with the same level, regardless of the volume fader setting.
The volume fader adjusts the level of the monitoring signal, not the input signal. The recording level remains the same, since it has no relationship with the level of the monitoring signal.
To decrease or increase the recording level, you have to adjust the gain of the signal source in your audio interface or mixing console.

Logic Pro/Express: Faders or Buttons on Control Surface trigger MIDI notes instead of expected functions

Thu, 1 Mar 2007 12:05:39 -0600

Issue or symptom

When you use buttons or faders on a control surface with Logic, the controls may not act as expected. If a Software Instrument or MIDI track is selected, the faders and buttons may trigger MIDI notes.

Products affected

Logic Pro

Logic Express

Solution

This can happen if a MIDI interface or USB keyboard is disconnected while Logic is running. Avoid changing your physical MIDI setup while Logic is running. If this does happen, reconnect the missing device, or quit and relaunch Logic.

Logic Pro 7: Audio artifacts when using Pitch Correction

Wed, 6 Apr 2005 13:12:49 -0500

When you use the Pitch Correction plug-in on audio tracks that have sudden large changes in pitch, the plug-in may introduce audio artifacts if the Pitch Correction "Response" parameter is set to respond too fast. To resolve this issue, try lowering the Response setting until the artifacts are no longer audible.

Logic: Defining custom bank messages

Sun, 19 Feb 2006 22:00:00 -0600

Logic offers several preset bank select message formats, but in some cases you will need to define a custom message format to change banks on a particular synthesizer. Most synthesizers use a combination of Control 0 (Bank MSB) and Control 32 (Bank LSB) events to trigger bank changes. MSB and LSB stand for "most significant byte" and "least significant byte," respectively. Consult the MIDI implementation chart for your synthesizer to determine the particular combination it requires for bank changes.

Here's how to set Logic up to send custom bank messages:

In the Environment, select the Multi Instrument for the

Logic Pro/Express quits when launched on an Intel-based Mac

Fri, 24 Feb 2006 18:38:35 -0600

Logic Pro or Logic Express version 7.2 may unexpectedly quit during launch on an Intel-based Macintosh.

This happens if the control surface preference file located at ~/Library/Preferences/Logic/com.apple.logic.pro.cs (Logic Pro) or ~/Library/Preferences/Logic/com.apple.logic.express.cs (Logic Express) is copied from a PowerPC-based Mac to an Intel-based Mac.

To resolve the issue, delete the file and then launch Logic.

Logic Pro, Logic Express: Unable to bounce QuickTime Music Synthesizer tracks

Mon, 14 Feb 2005 14:13:33 -0600
If you have tracks that trigger the internal QuickTime Music Synthesizer in a Logic project and then select them as part of a bounce, these tracks will not be included in the audio output. This is because it's not possible to directly bounce the audio output from the QuickTime Music Synthesizer within a Logic Pro or Logic Express session.
As a workaround, assign the affected track to the AU-Audio Instrument DLSMusicDevice. This uses the same QuickTime synthesizer, including the ability to listen to program changes. Like any Audio Instrument, you can bounce it both realtime and offline.

Logic Pro 7.1: Changes to AAF support

Tue, 12 Apr 2005 09:32:22 -0500

Logic Pro 7.1 uses an implementation of the Advanced Authoring Format (AAF) specification, which may affect its exported file compatibility with certain applications.
Due to changes in the AAF specification, AAF files exported from Logic Pro 7.1 will not work with ProTools 6.4 or 6.4.1, though they will work with ProTools 6.7. However, Logic can open AAF files exported from ProTools 6.4, 6.4.1, or 6.7.

Logic Pro 7: Wrong time signature position in Score

Thu, 21 Oct 2004 11:59:48 -0500
When viewing a score in layout view mode, some sequences may show a time signature change at the beginning of the stave line instead of the actual position of the time signature change. Additionally, double bar lines at these positions are not drawn through all staves. When looking at the single sequence in the Score editor, the bar position is correct.

This may happen if:
An automatic multi rest had been inserted manually into the sequence which shows the wrong time signature position.
The multi rest is placed in the bar before the time

Logic Pro 7: Use QuickTime DV format to get smooth playback over FireWire

Wed, 6 Oct 2004 07:53:33 -0500
Logic Pro can send video over FireWire to a video converter or DV camera. If movie playback stutters and some frames seem to be dropped after doing this, then the video may not be in the QuickTime DV format.
This happens because video that isn't QuickTime DV format must be converted in real time before it is transferred to the FireWire DV converter. This conversion is a very CPU intensive task and may lead to dropouts if the processor cannot handle the stream in real time.
Thus movies output to a FireWire video converter or a

Logic: JazzText font displays as black squares

Logic Pro 7: Surround joystick may not work reliably for surround automation

Wed, 24 Nov 2004 08:29:15 -0600
When using a mixing console (such as the Roland SI-24) for surround panning in Logic, you may experience erratic behavior when using the console's surround joystick--the surround position in Logic doesn't always change.
To resolve this issue, update to Logic Pro 7.0.1 or later.

Logic Pro 7: Freeze files will not play before the first bar

Tue, 12 Oct 2004 13:10:41 -0500
After using the Freeze function, all material that was located before bar 1 will not play.
Symptom
If the song start is set before the first bar, and a track containing regions before bar 1 is rendered with the Freeze function, then the material before bar 1 remains silent when playing back the song.
Products affected

Logic Pro 7.0.0
Solution
Set the song start to bar 1 and move all regions to a later position.

Logic Pro 7: How to fix the position of a marker

Wed, 3 Nov 2004 17:40:26 -0600
Learn how to fix the position of a marker on the timeline.
Markers are by default linked to their bar position, not to a time based position. This means that a marker will move in time when changing the tempo of the song. As an exception, markers that have been created by analyzing the scene cuts of a movie are automatically linked to their SMPTE time position.
Markers can also manually be linked to the SMPTE time position rather than the bar position. Use the "Lock SMPTE Position" command for this:

Logic Pro 7.1: Progress bar stops progressing when loading Elastic Audio tracks into RAM

Wed, 16 Mar 2005 19:36:03 -0600

A new feature in Logic Pro 7.1 is Elastic Audio, which enables your recorded tracks to follow any tempo changes you make after you've recorded them. However, the progress bar that displays when Logic loads Elastic Audio tracks into RAM may stop progressing if there isn't enough RAM to load the files.

If this happens, abort the process by pressing Command-period (.).

So how much audio can you load into RAM at any given time? This will depend on the following:

The amount of physical RAM in your computer

The number of other open applications

The amount of RAM being used

Logic Pro 7: Bouncing a DAE output creates an empty audio file

Fri, 10 Dec 2004 06:16:56 -0600
After clicking the Bounce button on a DAE output channel and confirming the Bounce dialog, you may come across a situation in which no progress bar appears and the bounce seems to be performed faster than usual (it's done in a few seconds). The resulting audio file contains only silence.
This will happen if the bounce mode for Direct TDM tracks is set to Offline. In this case, the bounce mode setting for Direct TDM is taken into account although the bounce process is triggered in DAE. Thus, Logic tries to perform an offline bounce for DAE, which is not possible.

Logic Pro/Express: 7.0: Applying fades to Apple Loops makes them play in their original key

Wed, 16 Mar 2005 19:32:51 -0600

If you apply a fade to an Apple Loop in the Arrange window, the portion of the loop encompassed by the fade will play at the loop's original key and tempo, rather than the key and tempo of the song. This issue occurs with Logic Pro 7.0 and Logic Express 7.0.

The core issue is that Apple Loops do not support fades, so you shouldn't assign a fade directly to one. If you'd like to achieve the effect, export the Apple Loop (in the Arrange window, choose File > Export > Region as Audio file). Then bring the exported file

Logic Pro 7: Apple Loops transpose to the wrong octave

Wed, 6 Oct 2004 06:23:51 -0500
Transposing an Apple Loop to a higher pitch may result in the Loop being played back at a lower pitch, and vice versa.
Example: If an Apple Loop is transposed to sound 7 semitones higher, it will sound 5 semitones lower instead. So the Loop is harmonically correctly transposed, but not to the intended octave.
Transposing audio material is a technically complicated process which always implies a certain loss in quality. The higher the amount of transposition applied, the higher the quality loss. This is why Apple Loops are always transposed to the smallest possible

Logic Pro 7: MIDI clock is always sent to all ports

Thu, 21 Oct 2004 12:08:16 -0500
Even if you choose a specific port for MIDI clock transmission (File > Song Settings > Synchronization... > MIDI), the MIDI clock signal is still sent to MIDI port 0 (all ports).
MIDI Clock is always sent globally to the MIDI interface which then distributes it to all ports. This works similarly with all multi-port MIDI interfaces. This method has the advantage that the MIDI clock signal is sent only once to the interface and not multiple times for each output port, thus reducing the MIDI data stream.
Depending on your MIDI interface, you may filter MIDI clock

Logic Pro 7: No panorama information in the send signal

Wed, 20 Oct 2004 07:53:18 -0500
An audio signal routed via Send to a Bus remains unaffected by the pan setting of the Track.
When an audio track is panned hard left or right, the signal that is routed via a Send to a Bus does not reflect the original panning of the track. The signal is always sent as if it was panned to the center. Sends are always routed pre-pan (before the pan pot). Therefore the panning of the audio track does not affect the panning of the Send signal. This does not mean that stereo sends are mono. They carry a real stereo

Logic Pro/Express 7: Logic stores opened GarageBand files in the same location as the original

Wed, 16 Mar 2005 19:59:06 -0600

When you open a GarageBand song in Logic Pro or Logic Express, a folder is created at the same location as the original GarageBand song to hold the corresponding Logic song and all audio files that are needed to play it back. For example, if you have a GarageBand song named "My Hit Song" stored in your GarageBand folder (~/Music/Garageband), Logic will create a folder named "My Hit Song" in that same folder.

If you would rather store the song at another location, choose File > Save as Project in Logic to save the song and all audio files to

Logic Pro/Express 7.1: Bass Amp presets not available

Tue, 4 Oct 2005 17:31:47 -0500

After installing Logic Pro 7.1 or Logic Express 7.1, you may find that there are no presets available for the Bass Amp plug-in.

To resolve this issue, update to Logic Pro or Express version 7.1.1 or later, available at Apple Downloads.

Note: If the issue still isn't resolved, please run the Logic Installer again to ensure that the "GarageBand 2 Sound Library" is installed correctly.

Logic Pro 7: SMPTE time code is not written from within Logic Pro

Thu, 21 Oct 2004 12:06:13 -0500
When setting the SMPTE mode to "Generate" (File > Song Settings > Synchronisation... > Unitor), the Unitor8 does not start writing SMPTE time code. The Write LED on the Unitor8 does not light up, and no SMPTE signal is created.
You can generate SMPTE time code from within Logic Pro with the MIDI interface Emagic Unitor8, but not if if a daisy chain of Unitor8 and AMT8 interfaces is connected to the computer and the first interface is an AMT8.
The Unitor8 should always be the first interface in the chain. AMT8 interfaces should be cascaded from the Unitor8. Otherwise, the

Logic Pro 7: Tracks are not processed on a Node

Thu, 30 Sep 2004 19:12:24 -0500

Some tracks which have the Node button activated are not processed on a Node computer.
Although the Node button of some tracks has been activated, the tracks are not processed on the Node computer. This is indicated by the track Node button not turning blue like on other Node tracks.
This could happen for several reasons:
An Audio Instrument with multiple outputs is sent to a Node Audio
Instruments with multiple outputs cannot be processed on a Node. Only mono and stereo is possible. The Node does not have enough processing power to process the track

Logic appears to stop responding ("hang") while scanning Audio Units

Mon, 12 Jun 2006 12:57:05 -0500

Logic can appear to be unresponsive or stuck while scanning Audio Units.

This happens because a plug-in will sometimes generate a dialog box that must be dismissed before scanning can continue. In some cases, this dialog may be hidden behind the Logic splash screen. Click the AU Manager icon in the Dock to reveal the dialog, then dismiss it.

Logic Pro 7: Incorrect beat grouping in the Score editor

Thu, 21 Oct 2004 12:07:38 -0500
Symptom
The beat grouping setting in the time signature setting of the Score editor has no effect.
When the beat grouping default in a 7/8 measure is set to e.g. 3+4 or 3+2+2, the notes are beamed as 3+3+1. Other combinations of grouping settings and time signatures may also lead to incorrect results.
Products affected

Logic Pro 7.0.0
Solution
If the default beat grouping does not lead to the desired result, the notes can be beamed manually. Select the notes to be beamed and use the local menu function Attributes > Beaming> Beam selected (or the corresponding keyboard shortcut).

Logic Pro/Express 7.1: US-2400 control surface detected incorrectly

Wed, 16 Mar 2005 19:35:57 -0600

If you have a Tascam US-2400 connected to your computer, it will be detected incorrectly when Logic initially scans for control surfaces. The Tascam US-2400 should be detected as if it were a Logic/Mackie Control and two Logic/Mackie Control XTs. Instead the unit is detected as if it were a Logic/Mackie Control and two Mackie C4s. Additionally, the fader banks are in the wrong order. As a result, the control surface will not operate properly with Logic.

To resolve this issue, delete the control surfaces that Logic has automatically scanned and manually rescan the US-2400 by doing the following:
