Apple released a new version of Logic Pro X, its professional music production software, with performance updates for all users and optimizations that take advantage of the power of the all-new Mac Pro. 

Making full use of the Mac Pro hardware, Logic Pro X 10.4.5 will now support up to 56 processing threads, allowing pro music producers and film composers to work through demanding music projects with unprecedented ease, Apple says.

With the new Mac Pro — due later this year — Logic can now run up to five times the number of real-time plug-ins compared to the previous generation Mac Pro. 

Logic Pro X 10.4.5 increases the available track and channel count for all users, now supporting up to 1,000 audio tracks and 1,000 software instrument tracks, providing four times the number of available tracks. Additionally, Logic Pro X now supports 1,000 auxiliary channel strips, 1,000 external MIDI tracks, and 12 sends per channel strip. 

Users can also expect improved responsiveness of the Mixer and Event List when working with large sessions, and projects with numerous Flex Time edits and tempo changes perform more efficiently than ever, according to Apple.

Additional new features in Logic Pro X 10.4.5, include:

The loop browser can filter by loop type and allows drag and drop of multiple loops into your project simultaneously.

The redesigned DeEsser 2 plug-in provides more options to reduce sibilance on audio tracks.

MIDI beat clocks can be sent to individual ports, each with unique settings like timing offset and plug-in delay compensation.

Logic Pro X 10.4.5 is available today as a free update for all existing users, and is available on the Mac App Store for $199.99 for new customers. For more information, visit apple.com/logic-pro.
