How to Use Smart Tempo in Logic Pro

Here is how to use Smart Tempo in Logic Pro: choose a project tempo mode — Keep, Adapt or Automatic — so Logic either holds your set tempo, follows the tempo of what you play, or detects and matches it on the fly. Smart Tempo lets you record without a click and still end up with everything in time.

This guide assumes you have Logic Pro open and either want to record freely, or you have an existing recording or loop whose tempo you need to work with.

What Smart Tempo solves

Traditionally you record to a fixed click and everything lines up to that grid. Smart Tempo adds flexibility: it can detect the tempo of a freely played performance and bend the project to follow it, or conform an imported loop to your project tempo. That means you can capture a take that breathes naturally, then still edit and quantise it later.

The three Smart Tempo modes

The project tempo mode is the master switch:

• Keep: the project tempo stays fixed. This is classic behaviour — you play to the click and the grid does not move.
• Adapt: the project tempo follows the tempo of your recordings, so Logic reads the feel of what you played and adjusts the tempo map to match.
• Automatic: Logic decides per recording whether to keep or adapt, based on whether you recorded to the click or freely.

Set this in the LCD/tempo display area before you record so Logic handles the take the way you intend. Getting the mode right up front saves a lot of cleanup, because trying to switch a project from Keep to Adapt after recording can shift the timing of material that was already in time.

Recording without a click

1. Set the project tempo mode to Adapt (or Automatic).
2. Turn the metronome off and record your part — play with natural feel.
3. Logic analyses the take and creates a tempo map that follows your performance.
4. Now the grid lines up with what you played, so later overdubs and edits stay in time.

Conforming audio to the project tempo

For loops and imported audio, Smart Tempo can detect the file’s tempo and stretch it to your project. Each audio region has a Smart Tempo setting controlling whether it keeps its own tempo, conforms to the project, or follows. This is closely related to Logic’s Flex tools — for surgical timing edits use Flex Time in Logic Pro, and for pitch correction Flex Pitch in Logic Pro. The general principles of stretching audio without artefacts apply across DAWs — see how to time-stretch audio in a DAW.

When to use Keep vs Adapt

Use Keep for click-based, electronic or sample-driven projects where a rock-solid grid matters. Use Adapt for live, expressive performances — a solo piano take or a band jam — where the feel should drive the tempo. Automatic is a safe default if you switch between both. Whatever you choose, a reliable reference click helps when you do want to play in time; see how to make a click track in a DAW. For more Logic tutorials, visit the mixing and mastering hub.

Frequently asked questions

What does Adapt mode do in Smart Tempo?

Adapt makes the project tempo follow your recordings. Logic analyses the feel of what you played and builds a tempo map to match, so the grid lines up with a freely played performance instead of forcing it onto a fixed click.

Can Smart Tempo match an imported loop to my song?

Yes. Set the region’s Smart Tempo behaviour so it conforms to the project tempo, and Logic detects the loop’s tempo and time-stretches it to fit your song.

Will Smart Tempo change a recording I made to the click?

In Keep mode, no. In Automatic mode, Logic recognises that you recorded to the click and keeps that tempo. Adapt is the mode that actively moves the project tempo to follow your playing.
