Apple just pushed out updates to Logic Pro 9 and Logic Express, bringing both up to version 9.1.8 and introducing a ton of fixes and performance enhancements. The update is also for the Mac App Store version of Logic Pro.

Release notes for both below:

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
