On January 28, Apple will release Logic Pro 12 and MainStage 4.0. The update introduces Synth Player, a new AI-powered Session Player for electronic parts, Chord ID, which instantly turns audio or MIDI into chord progressions, an expanded Sound Library, and smarter sound search on iPad. Together with improvements to live performance in MainStage, this release focuses on helping musicians move faster from an idea to a finished track - in the studio and on stage.
Logic Pro 12
One of the most important additions is Synth Player, a new member of Logic’s AI Session Player family. Synth Player can generate musical synth and bass performances that follow your chords and song structure.
Using Synth Player feels like working with a skilled synthesist who can instantly try new ideas when you’re stuck. You can keep things simple or push the performance further using intuitive controls for complexity and intensity. For advanced users, deeper parameters allow more detailed control over articulation and behavior. Importantly, Synth Player is not limited to Logic’s internal instruments - it can also use third-party Audio Units or even control external hardware synthesizers.
Another key feature is Chord ID. This tool acts like a personal music theory assistant inside Logic. You can drop in any audio or MIDI recording, and Logic will automatically analyze it and extract the chord progression. This removes the need for manual transcription and makes it much easier to build songs from demos, loops, or recorded ideas.
Chord ID connects directly to Logic’s chord track, which means it also drives the behavior of AI Session Players like Synth Player. Once your chords are identified, you can quickly audition different players, styles, and musical approaches. This makes experimentation fast and playful — you can explore different vibes without rebuilding your project from scratch.
Logic Pro 12 also expands its Sound Library with new Apple-designed sound packs and Producer Packs. These include hundreds of royalty-free loops, samples, instrument patches, and drum sounds.
For Logic Pro on iPad, Apple brings over Quick Swipe Comping, a long-standing feature from the Mac version. This makes it easy to create clean, seamless vocal or instrument takes by quickly swiping through multiple recordings.
The iPad version also introduces Music Understanding features. Instead of browsing sounds using tags and filters, users can search the Sound Browser using natural language. You can describe the kind of loop you’re looking for, or even use an existing recording to find something similar. Logic uses AI to understand its sound library and return results that actually make musical sense.
Mainstage 4.0
MainStage turns your Mac into a live instrument, vocal processor, or guitar rig. The biggest advantage is continuity: the sound you design in Logic can be the exact sound your audience hears on stage. There’s no need to recreate patches or compromise between studio and live setups.
Apple emphasizes reliability and speed. Setup is fast, teardown is even faster, and the experience in between is designed to be stable and predictable — which is exactly what live performers need. MainStage 4.0 fits naturally into the Logic ecosystem, especially for keyboard players, electronic musicians, and hybrid live setups.
Apple Creator Studio
Both Logic Pro 12 and MainStage 4.0 are also available through new Apple Creator Studio. This subscription gives creators access to Apple’s professional creative tools, including Logic Pro, MainStage, and Final Cut Pro.
Apple Creator Studio is aimed at musicians who also work with video and content creation. You can still buy Logic Pro as a one-time purchase on Mac, but the subscription option offers a unified workflow across music and video inside the Apple ecosystem.
Apple Logic Pro 12 and Mainstage 4.0 will be available on January 28th.
