When it announced the long-awaited Mac Pro relaunch onstage at WWDC last week, Apple settled on creative pro software as the best way to illustrate the desktop’s power. Along with Final Cut, Logic was one of the centerpieces of that introduction.

Today the company issued the update to Logic Pro X illustrated onstage. Version 10.4.5 of the pro-level music production software supports up to 56 processing threads, and up to 1,000 audio tracks and software instrument tracks.
