How it works
- 1 · Share
Share a project
Pick your Live project folder. It stays where it is. Your collaborator clicks Get a copy.
- 2 · Take
Take the set
You get the newest version, and everyone else sees it's your turn.
- 3 · Save
Save a version
Work in Live as usual, write a few words, save. Tandem lists what changed:
tempo 120 → 124. - 4 · Hand back
Hand it back
Tandem checks it plays on their side first. Then it's their turn.
Your
turn.
Take the set before you start. You get the newest version, and everyone else sees it's your turn. One of you at a time: no more "conflicted copy".
Their
turn.
Before you hand back, Tandem checks it plays on their side, and tells you how to fix what won't.
- ✕Your collaborator has Live 12.3.1; the set needs 12.4.3.→ Update Live on their computer.
- !'Strings' uses Kontakt 7, which your collaborator doesn't have.→ Freeze the track before handing over.
- ✓All 46 samples are inside the project.
The
mix.
Every save is a version with who, when and what changed. Compare any two, and bring a track back from last week.
tempo 120 → 124 BPM + track 'Pad': Wavetable ~ 'Vocals' −6 dB − clip 'Riser'
Mac ⇄ PC: Tandem knows which plugins and Live versions each computer has.
Just
you.
No one else needed. Tandem keeps one set per project with every version behind it, and tells you what's named badly before it's a mess.
- ✓One set: Night Drive.als12 versions, each with what changed. No more v3 FINAL mine.als.
- !'1-Audio' and '4-MIDI' still have default names→ Your rules: DRM, BAS, VOX, one colour each
- !Recording 'Audio 0001 [2026-11-10 221503].wav'→ Name it after its track, like VOX Lead take 3
Planned: rename to your rules in one click, bounce names from a template, and new projects that start from a folder and project template.
Bar

Listen to a save without opening Live: the bounce, or every stem. Leave a note right where it happens, and see it ticked off in the save that fixes it.
Our
rules.
Agree at the start how you work: names, who does which part, how long a turn lasts, and what you do before you hand back. Tandem keeps you to it.
- Start124 BPM · F minor · Live 12.4
- Names
DRMBASVOX, one colour each - Your turndrums and bass, up to 3 days
- Before hand backbounce what you touched · freeze · leave a note
- Their turnvocals and arrangement
Right
now.
See who has the set open and what they just changed. Claim your tracks and work at the same time; Tandem brings everyone else's parts into your set.

Before you start
On your own? Install Tandem, add your project, save. That's all.
With others?
- Everyone installs Tandem and has Ableton Live 12.
- One shared folder. Make a folder called Tandem in Dropbox (or Google Drive, iCloud Drive…) and share it with your collaborator. Tandem shows how after you share your first project. Everything you share later goes through it too.
- Make it available offline on every computer, so the files are really there and not only in the cloud.
- Keep your projects outside that folder, for example in Music. Tandem copies saves in and out, so the sync service never touches a set while Live is writing it.
