This update improves overall stability and addresses some minor issues including the following:
- 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.
This update is recommended for all users of Logic Pro 9.
