a player for the players.
Take any song apart. Slow it down, loop any part, change the key,
split it into stems and a whole lot more.
See it work.
Drop a song in and Lio maps it: key and tempo detected on your Mac, sections marked on the waveform, any part loopable, speed from 50 to 150 percent without changing pitch, and stems you can mute or solo. The interactive demo needs JavaScript, but that is the whole trick.
A rehearsal tape, split into songs.
Drop in one long recording (a whole rehearsal, a practice session) and Lio finds the breaks and splits it into separate songs.
Nudge any split that's off, then they land as a setlist: each take its own track, ready to loop and slow down.
Your library, your sets.
Import a folder of songs, or pull from your Music app library. Every track lands with its key, tempo, and beats worked out automatically on your Mac, the moment it's added.
Browse by Songs, Recents, Setlists, or your own Tags. Long lists sort A→Z (Hebrew too), so any song is a glance away. Pull tracks into a setlist, reorder with a drag, switch sets in one click.
In step on every Mac.
Turn on iCloud sync and your whole library follows you — songs, sections, loops, charts, and where you left off. Mark a chorus on the studio Mac, and it's on your laptop at rehearsal.
It all travels through your own private iCloud. Nothing is ever stored on our servers, and sync is free on every plan.
Send & receive setlists.
Hand a song (or an entire setlist) to another Lio user. It lands as an imported setlist, your loops, sections, detected key, and edits all intact.
Or save a copy to share however you like: AirDrop, email, a shared drive. And if a song shows up without its audio file, Lio marks it "No audio" and lets you point at the file on your Mac.
Record from your Mac.
If you can hear it on your Mac, Lio can record it. Pick the app that's playing, watch the level meter, and hit record. What you capture lands as a brand-new song, with its key and tempo detected automatically. Free covers three a month; Pro lifts the cap.
Your chart, a glance away.
Keep each song's chord chart, lead sheet, or sheet music right next to it — any PDF or image works. Drag it onto the player and it's attached.
Charts open in their own window that can float above everything, and it always shows the chart for the song you're practicing. Share the song, and the chart travels with it.
Questions? We've got answers.
Still stuck? Email support@lioplayer.com.
Is there a free version?
Yes, and it's a real one, not a teaser. Download it and you can open any song, slow it down, and loop sections for as long as you like. Pro adds key changing, stem separation, the section editor, song charts, unlimited recordings and rehearsal splits, and the full library + setlists.
How much is Pro?
$36 a year, or $126 once and you're done. Both cover Pro on up to 2 Macs.
Does it work on Intel Macs?
Lio is built for Apple Silicon Macs (M1 and later) running macOS 14 Sonoma or newer. Intel Macs aren't supported.
Where do my files go?
Nowhere, unless you say so. The app runs entirely on your Mac, stem separation included. If you turn on iCloud sync, your library is copied into your own private iCloud so your other Macs can pull it down — we never see your files and run no servers of our own. Getting Pro takes a quick sign-in with Google or email; after that it works offline.
Does it sync between my Macs?
Yes. Flip on "Sync library with iCloud" in Settings and your songs, sections, loops, charts, and practice state stay in step across your Macs — automatically, through your own iCloud. It's free on every plan, and you can turn it off anytime.
What formats does it read?
mp3, m4a, wav, flac, aac, and aiff. Drag a file onto the window or import a folder. Apple Music subscription tracks (DRM) aren't supported.
What can I record from?
If you can hear it on your Mac, Lio can record it: any app, any website. Pick the one that's playing, hit record, and it lands as a new song with its key and tempo detected. It records just that one app, so notifications and other sounds stay out. You're responsible for having the right to use what you record. Free covers three recordings a month; Pro removes the cap.
Refunds?
