Pro Studio 9 would no longer be available on DVD, and would only be sold via the Mac App Store. The price was reduced from $499 to $199.99 for the Logic Pro app, and $29.99 for MainStage. The download was just over 400MB, and 19GB of optional loops were available as in-app downloads. This version of Logic Pro Studio 9 no longer allowed users to access any microtunings in Scala format other than those provided with the software by Apple. Logic Pro X Released as successor to Logic Pro 9 on July 16, 2013, Logic Pro X (10.0.0) included a new, single-window customizable interface, with a design in line with Final Cut Pro X, as well as new features. New tools in this release are Drummer, a virtual session player that automatically plays along with your song in a wide variety of drumming styles and techniques, and Flex Pitch, a Flex Time equivalent for pitch editing in audio recordings.

Further improvements were made to score editing, exporting (now compatible with MusicXML format), and this version introduced MIDI plug-in compatibility. Coinciding with the release of Logic Pro X was the release of a companion iPad app called Logic Remote, which allows wireless control of Logic Pro X, including Touch Instruments for playing and recording software instruments as well as tools for navigating, making basic edits and mixing. Since this release, Logic Pro X runs in 64-bit mode only and no longer works with 32-bit plug-ins. Logic Pro X is capable of transferring most data from previous projects saved in Logic Pro 5 and later, though the transfer to 64-bit only means older 32-bit plugins will no longer work. Logic 10.4 introduced a new reverb called ChromaVerb, and new functionality such as Smart Tempo, as well as the option to
