Apple has just released minor updates for both Logic Pro and Logic Express, bringing them to version 9.1.8. While no new functionality was added to either application with this update, a lot of persistent compatibility issues with OS X Mountain Lion and Lion have finally been fixed. If you’d like to view the release notes, we’ve embedded them after the break.

About the Logic Pro 9.1.8 Update:

General

  • Additional content downloads now behave correctly when installing on OS X Lion and OS X Mountain Lion.
  • Resolves an issue in which the Save As command sometimes resulted in an alert dialog in Logic 9.1.7.

Audio

  • Fixes an issue that caused an Airplay dialog to repeatedly appear.
  • Relaunching the audio driver now reliably applies changes made to the buffer size.

Performance and Stability

  • Resolves performance issues when using plug-ins that provide frequent graphic feedback.
  • Resolves an issue that could cause an abnormally large monitoring delay after a computer wakes from sleep.

Plug-ins and Instruments

  • Fixes an issue with ES2 that could create distortion when a sidechain was used as the modulation source.
  • Tuner now responds consistently when used in a channel strip that also contains plug-ins which introduce latency.
  • The MIDI channel for a multi output software instrument is no longer changed when adding Aux outputs when there are regions on the track.

Compatibility

  • Logic now properly maintains Aux assignments for multi-output instances of Kontakt that are migrated from earlier versions to Kontakt 5.
  • Resolves an issue in which deleting tracks took longer than expected if Melodyne Editor was inserted on a track.

If you’re unaware, Logic is Apple’s pro level recording and audio editing software for the Mac. Logic Express is currently aimed for the self recording amateur musician while Logic Pro is used in many recording studios worldwide. Both of these apps are available via the Mac App Store.
