Apple has updated Logic to version 9.1.4.

Compatibility:

• Logic can now open songs created by GarageBand for iPad.

Performance and Stability:

• Logic now provides more specific messaging when playback is stopped because of hard drive performance issues.
• Resolves an issue in which Logic sometimes performed very slowly after a project that was saved without assets was consolidated.
• Logic no longer quits unexpectedly when copying, pasting, or swapping voices between slots in Ultrabeat.

64-bit Mode:

• Resolves an issue in 64-bit mode in which a generic interface for some 32-bit plug-ins was displayed.

Automation:

• Resolves an issue in which moving a region to a different Arrange track assigned to the same channel strip could cause automation to be deleted.
• Drag-copy of automation curves now works as expected on grouped tracks.
• Moving an automation node that lies between two other nodes of the same value to the left or right no longer causes it to decrease by -0.1 db in value.
• Resolves an issue introduced in Logic 9.1 in which performing Undo after using the "Move Visible Track Automation to Region" command would delete the automation.

Audio Editing:

• Resolves an issue in which performing Undo after creating an alias for a region would shorten the region in No Overlap mode.
• Audio Regions that contain slashes in the name can now be successfully merged using the Glue Tool or Merge command.
• Quantization of audio regions that have stretched or compressed and contain tempo information now works reliably.
• Quantize and Q-Strength now work properly on regions created by exporting a Comp from a Take Folder.
• Resolves an issue where lengthening an audio region could sometimes cause the audio to unexpectedly stretch.
• Performing Undo after flattening Takes on a group of flexed tracks now works as expected.
• Takes no longer sometimes display as soloed when their parent Take folder is disclosed but not selected.
• Resolves an issue in which moving a take region with Quick Swipe Comping disabled sometimes did not move the corresponding take region(s) in tracks within the same Edit Group.
• Fixes an issue in which dividing a take region that had been created by merging several take regions together could cause the area to the right of the edit to disappear.
• Resolves an issue in which moving a take region with Quick Swipe Comping disabled sometimes did not move the corresponding take region(s) in tracks within the same Edit Group.
• Fixes an issue in which dividing a take region that had been created by merging several take regions together could cause the area to the right of the edit to disappear.
• Resolves an issue in which importing a Take folder into a project with a matching track could cause existing takes to be removed from Take folders in the original track.

Control Surface Support:

• Resolves an issue introduced in Logic 9.1.2 in which pickup mode for generic control surfaces did not work as expected.

General:

• Resolves an issue in which the key commands Next Screenset and Previous Screenset were reversed.
• If the Startup Action preference is set to “Ask,” it is again possible to open a project by dragging it onto the Logic icon while the Startup window is open.
• The default region quantize setting is now maintained after importing channel strips from another project.
