The official list of bug fixes are really dissapointingly short. I hope more than the listed bugs are fixed! Or is Logic X bug fixing already slowing to a halt? Includes a change that allows Logic to properly open GarageBand X projects. Fixes an issue in which the Mixer might flicker when scrolling up or down in OS X Mavericks v10.9. Resolves an issue in which EXS instruments created with third-party applications might exhibit unexpected voice "stealing" when played in Logic Pro X. Resolves an issue in which the Tuner did not display correctly on Retina Displays with OS X Mavericks v10.9. Fixes an issue in which Logic Pro X did not correctly display track icons in projects imported from GarageBand 2 for iOS.
