Apple’s previous Logic update brought OS X Lion compatibility. The twist is that one shipped way back in May. Now, the mothership’s back with a fresh batch of tweaks and fixes — come inside for the details.

Apple has shipped Logic Express 9.1.5 (Download) and Logic Pro 9.1.5 (Download). Both products arrive with the same bullet points in the update summary:

• All instrument and effect plug-ins that use LFO’s synced to the beat now behave correctly
• The Toggle Zoom key command now returns to previous zoom level as expected
• Improved compatibility with Apogee’s Duet 2
• Full Logic Pro, Express 9.1.5 release notes
