Apple updates Logic to v9.1.2

Apple has updated Logic to version 9.1.2. This update improves overall stability, provides numerous fixes and improvements, and is recommended for all users of Logic Pro 9.

Performance and Stability:

  • Logic’s performance while playing movies at larger than 300% native size in 64-bit mode has been improved.
  • Resolves an issue that could cause the warning dialog “Memory Getting Low” to appear when simultaneously recording multiple tracks in 32-bit mode.
  • Resolves an issue that could cause the warning dialog “Specified volume doesn’t exist -35″ to appear when simultaneously recording multiple tracks in 32-bit mode.
  • Using the Undo command after a “Bounce in Place” command now correctly reinserts used plug-ins on the channel strip.
  • Performing Undo after using the “Bounce – Replace All Tracks” command now correctly restores all automation.
  • Resolves an issue that sometimes caused Logic to stop responding when loading a setting for a mono plug-in in a multi-mono surround configuration.


  • Improves compatibility with 6- and 12-core Mac Pro systems.
  • Supports iOS control surface apps that utilize the OSC protocol.
  • Supports REX files when running in 64-bit mode.
  • Improves compatibility with select Audio Unit plug-ins.
  • The expanded System Performance window now accurately reflects the number of available real cores on all supported computers.
  • Logic no longer inadvertently reloads the content for third-party sampler plug-ins such as Native Instrument’s Kontakt after tracks are deleted, or after some other edits are performed.
  • Resolves an issue introduced in Logic 9.1.1 that could cause the spacebar to incorrectly trigger playback in Logic while the Melodyne plug-in window had focus.
  • Logic Control or Mackie Control hardware control surfaces no longer switch to plug-in edit view when a plug-in on slots 8-15 is removed.

MIDI Editing:

  • Resolves an issue introduced in Logic 9.1 where using the Marquee tool to trim the end of a MIDI region could extend the number of loops for regions earlier in the same track.
  • The Piano Roll now updates as expected to show the currently selected MIDI take.
  • Resolves an issue in Logic 9.1.1 which could cause the Score to not display all notes from a region that had been split with the Scissors tool.
  • The appearance of downward slurs and ties has been improved in the Score window.
  • When pasting MIDI events into the Arrange area, the playhead no longer jumps unexpectedly to a position far to the right of the end of the pasted content.

Instruments and Effects:

  • Amp Designer now reliably maintains saved non-default EQ settings when a project is reloaded.
  • The Wah Wah stompbox now responds more reliably to expression pedal input.
  • EXS24 loads and plays back instruments that use short AAC or ALAC audio files when Virtual Memory is disabled.
  • Corrects an issue that could cause the “Next Plug-in Setting or EXS Instrument” key command to change settings on the wrong plug-in.

  • Software Instrument tracks with the AUNetReceive plug-in no longer exhibit excessive latency.
  • The Noise Gate no longer creates audible clicks while processing audio with the plug-in GUI open.
  • Double-clicking an insert slot will close the associated plug-in if it is open and set to Link Mode.
  • In the EXS Editor, a mouse roll over of an audio file name now displays the full path for the file.

File Handling and Management:

  • Resolves an issue which sometimes caused the text after a period in a plug-in setting name to be lost on the first save of the setting.
  • Resolves an issue from Logic 9.1.1 which forced exported MIDI files to have a .logic extension rather than the .mid extension.
  • Import of folder tracks from other projects now works reliably.
  • Bank and Patch names in Multi-instruments now import correctly when using the Track Import feature.
  • Resolves an issue which could cause the Track Import window to become non-functional in certain rare cases.

  • The EXS24 now automatically locates samples stored in a folder inside the Project Folder that have any of the following names: “Samples,” “Sampler Files,” “Sampler Instruments,” or “Audio Files.”.
  • When a project is opened from a project folder that has been copied, EXS24 now loads samples from the copied location instead of the original.
  • It is now possible to drag and drop an AIFF audio file copied from a CD into the Audio Bin in the Media area of the Arrange window.
