What a tempo map is and why you need one

A tempo map is a set of instructions that tells your recording software to play back at different speeds at different points in a song. Instead of locking everything to one tempo — say, 120 beats per minute for the whole track — a tempo map lets you slow down for a bridge, speed up for a chorus, or follow a live drummer who drifts slightly. PreSonus Studio One stores these tempo changes on a single track that runs alongside your audio and MIDI, so every instrument follows the same map.

You need a tempo map when you are working with a live recording that was not metronomically perfect, when you want intentional tempo shifts for musical effect, or when you are syncing to video that requires specific timing at specific moments. Without a tempo map, you would have to either accept the timing as-is or manually stretch and compress individual tracks — which takes much longer and sounds worse.

Key Takeaways

  • Open the Tempo track by clicking the tempo display in the transport bar at the top of Studio One, then click "Edit Tempo Map".
  • Click on the tempo curve in the editor to add a tempo point, then drag it up or down to change the speed at that exact moment in the song.
  • Use the pencil tool to draw smooth tempo curves instead of clicking individual points, which is faster for gradual tempo changes.
  • Test your tempo map by playing back the song and listening for places where the grid no longer matches the audio, then add or adjust points as needed.
  • Lock the tempo map when you are finished so accidental clicks do not shift your tempo points.

Opening the tempo track and editor

The tempo track lives at the very top of your arrange window in Studio One, above all your audio and MIDI tracks. If you do not see it, right-click in the track list area on the left and select "Show Tempo Track" from the menu. The tempo track shows a blue line that represents your current tempo across the entire song.

To edit the tempo map, click the tempo number in the transport bar at the top of the window — it usually shows something like "120.00" in the upper left. A small menu appears. Click "Edit Tempo Map" and the tempo editor opens in a new panel below your arrange window. This editor shows the same blue line but with a grid and zoom controls so you can see and adjust individual tempo points.

Adding tempo points by clicking

In the tempo editor, click anywhere on the blue line to add a tempo point at that location. The point appears as a small circle on the line. Once you have placed a point, you can drag it up to increase the tempo or down to decrease it. The number in the top left of the editor updates in real time to show you the exact tempo at that point.

Each point you add becomes a waypoint that Studio One uses to calculate the tempo between points. If you add two points and drag one higher than the other, Studio One automatically creates a smooth ramp between them — the tempo gradually speeds up or slows down across that section. This is useful for ritardando (gradual slowdown) or accelerando (gradual speedup) effects.

To remove a point, right-click on it and select "Delete" or straightforward click it while holding Alt (or Option on Mac). Be careful not to delete your starting point — Studio One needs at least one tempo point to function.

Using the pencil tool for smooth curves

If you need to make many small tempo adjustments across a section — for example, to follow a live drummer who speeds up and slows down slightly throughout a verse — the pencil tool is faster than clicking individual points. Select the pencil icon in the tempo editor toolbar, then click and drag across the section you want to adjust. As you drag, you draw a curve directly onto the tempo line.

The pencil tool creates multiple points automatically as you draw, so you can shape the tempo curve freehand. This is much quicker than placing points one at a time, especially if you are trying to match a performance that has natural micro-timing variations. You can always go back and clean up the curve by deleting unnecessary points or adjusting individual ones.

Matching the tempo map to your audio

The real work of tempo mapping is listening and adjusting. Play back your song and watch the grid in the arrange window. Where the grid lines up with the beats in your audio, your tempo is correct. Where the grid drifts ahead of or behind the audio, you need to add or adjust a tempo point.

A common workflow is to zoom in on a section where the grid is drifting, add a tempo point at the moment the drift starts, then drag that point up or down until the grid realigns with the audio. Then move to the next problem area and repeat. This is tedious but necessary if you are working with a live recording or a performance that has intentional tempo changes.

Use the playhead (the vertical line that moves across the editor as the song plays) to pinpoint exactly where a tempo change needs to happen. Pause playback, position the playhead at the exact beat where the timing shifts, then add a point right there.

Locking the tempo map when finished

Once your tempo map is complete and tested, lock it so you do not accidentally move a point while editing other parts of your session. Right-click on the tempo track header and select "Lock Tempo Track" from the menu. The track turns gray to show it is locked, and you can no longer click or drag points.

If you need to make changes later, right-click again and select "Unlock Tempo Track". This is a safety measure that takes one second but prevents hours of frustration if your hand slips while you are scrolling or selecting regions.

Common mistakes and how to avoid them

The most common mistake is adding too many tempo points. Every point you add is a calculation Studio One has to make, and too many points can create an unnatural, jittery sound. Start with the minimum number of points needed to match your audio, then add more only if the result sounds wrong.

Another mistake is forgetting that the tempo map affects everything in your session. If you add a tempo point in the middle of a song, all your MIDI tracks, audio stretching, and automation will shift to match. This is usually what you want, but it means you cannot use the tempo map to fix timing on just one track — you have to fix the source audio or use time-stretching on individual tracks instead.

Finally, do not assume your tempo map is finished after one pass. Listen to the whole song at least twice, with fresh ears if possible. Tempo drifts that sound fine at first often become obvious on a second listen.

Frequently Asked Questions

Can I use a tempo map with a click track?

Yes, but the click track will follow your tempo map exactly, which means it will speed up and slow down with your song. If you want a steady click to help you stay in time while you record, turn off the tempo map or use a fixed tempo instead. You can always add the tempo map after recording is finished.

What if I want different tempos in different tracks?

You cannot — the tempo map applies to the entire session. If one track needs a different tempo, you have to time-stretch that track individually using Studio One's time-stretch tool, which is found in the audio editing panel. This is slower than using a tempo map but necessary when tracks were recorded at different tempos.

How do I export a song with a tempo map?

The tempo map is baked into your session, so when you export audio, the exported file will play back at the tempos you set in the map. You do not have to do anything special — just export normally. The tempo map only affects playback within Studio One; it does not change the actual audio file.

Can I copy a tempo map from one song to another?

Not directly, but you can export the tempo map as a text file and import it into another session. Right-click the tempo track and look for export or save options. The exact steps depend on your version of Studio One, so check the manual if you cannot find the option in the menu.
