How to tempo map in Ableton Live.
Ableton Live has no built-in tempo detection and cannot export tempo maps. But it does import tempo data from MIDI files — with one condition: the file must contain notes spanning the tempo changes. TempoSync's MIDI export includes click events across the whole track, so it meets that condition. Here's the full workflow.
The built-in way
Warp markers and manual tempo automation.
Live gives you warp markers and a tempo automation lane on the Master track, but nothing automatic — you detect and draw tempo changes by hand, and the result stays locked inside the set.
- 01
Warp the recording
Drop the audio into Arrangement view and let Live warp it. Fix the warp markers so transients sit on the grid.
- 02
Draw tempo automation
Open the Master track in the Mixer and choose Song Tempo. Draw tempo automation that follows the recording's changes.
- 03
Check against the click
Play back with the metronome and adjust the automation until the grid follows the performance.
The fast way
Import a MIDI tempo map instead.
Live imports tempo and time-signature data from MIDI files — as long as the file contains notes spanning the full length of the tempo changes.
- 01
Export the tempo map from TempoSync
The MIDI file contains the tempo map plus click events (notes) across the whole track — exactly what Live needs.
- 02
Drag the MIDI file into Arrangement view
Live asks whether to import tempo and time signature data. Click Yes — the tempo automation appears on the Master track under Mixer → Song Tempo.
- 03
No prompt? Restore the warnings
If Live doesn't ask, the dialog was hidden earlier. Go to Preferences → Look and Feel and restore the "don't show again" warnings, then re-import the file.
If a MIDI file with tempo changes but no notes doesn't import, that's expected — Live ignores bare tempo maps. TempoSync's export always includes click notes spanning the track, so it imports correctly.
The TempoSync workflow
From recording to tempo track.
1. Upload your recording — a live take, a drum recording, or anything recorded without a click.
2. Export the MIDI tempo map, along with a WAV click track if you want one.
3. Import the MIDI file using the steps above. Your tempo track follows the recording.
Comparison
Built-in tools vs TempoSync.
| Built-in | TempoSync | |
|---|---|---|
| Availability | No tempo detection, no tempo map export. | MIDI tempo map import works in all Live editions. |
| Effort | Warp markers plus hand-drawn automation per song. | Automatic detection on upload. |
| Output | Tempo automation inside the current set only. | Tempo map, WAV click track, and MIDI file reusable anywhere. |
| Learning curve | Warping is powerful, but entirely manual. | Upload, export, import. |
FAQ
Tempo mapping, answered.
Can Live export a tempo map?
No — Ableton's documentation confirms Live has no tempo map export. The reverse direction (import) works through MIDI files, which is why TempoSync exports one.
Why didn't Live ask about importing tempo?
The dialog was hidden with "don't show again". Restore warnings in Preferences → Look and Feel, then re-import the file.
The MIDI imported, but the tempo is missing?
Live ignores MIDI files that contain tempo changes but no notes. TempoSync's export includes click notes spanning the track, so it imports correctly.
Can I use the WAV click track in Live instead?
Yes — drop the click-only WAV into Live for practice or overdubs. For a tempo-synced grid, use the MIDI import.
Get the tempo map Live can't make on its own.
Upload the recording, export the MIDI tempo map, and drag it into Live. The grid follows the performance in minutes.
