Correct tempo analysis results using beat markers in Logic Pro for Mac

When the Smart Tempo Editor is in Beat Marker mode, detected beats are shown as editable beat markers in the main display. Beat markers for downbeats are more prominent than those for other beats. Instead of adding hints to improve the tempo detection as in Hint mode, in Beat Marker mode you can fine-tune the tempo analysis results by editing beat markers directly. In most cases, it is recommended that you first use Hint mode and see whether adding hints gives satisfactory results, then use Beat Marker mode if more precise edits are needed.

Each beat marker has several handles, each with a different function. When you hold the pointer over a handle, it displays a tag showing the handle’s function. You can make a selection before clicking a handle; if there is no selection, Logic Pro for Mac makes a default selection of the beats affected by the edit. Depending on the selection, not all editing functions may be available.

Because beat marker edits modify the tempo analysis results and aren’t affected by the analysis, they are ignored the next time a tempo analysis is performed. Before switching from Beat Marker mode to Hint mode, you may want to lock the range containing beat marker edits so that it won’t be affected by a new tempo analysis.

Note: When you tap the D or T keys on your computer keyboard while in Beat Marker mode, the Smart Tempo Editor switches to Hint mode, and the tapped keys add downbeat hints and beat hints.

Turn on Beat Marker mode

  • In the Logic Pro Smart Tempo Editor, click the Hint Mode button in the control bar to turn it off.

When you press the D key on your computer keyboard while in Beat Marker mode, the Smart Tempo Editor switches to Hint mode so that you can add hints using the D and T keys.

Edit beat markers

When you hold the pointer over a beat marker, a set of circular handles appears along the length of the beat marker. Holding the pointer vertically over each handle shows a tag describing the function of that handle. Press and hold the Command key while dragging a beat marker to have it snap to significant analysis points.

  • To set a beat as the downbeat: Place the pointer over the beat marker and click the Set Downbeat handle.

    Setting a beat as the downbeat also moves the region, unless the project tempo is set to Keep and Smart Tempo is set to Off. This handle isn’t available for beat markers already on a downbeat.

  • To move an individual beat: Click and hold the Move Marker handle and drag the beat marker to a new position.

  • To scale beat markers in a selection: Make a selection, click and hold the Scale Selection handle for a beat marker in the selection, then drag to scale the selected beat markers.

    If you drag a Scale Selection handle when there is no selection, Logic Pro automatically selects the bar in which the beat marker is located. If the beat marker is a downbeat, the preceding and following bars are selected.

  • To scale preceding beat markers and move following beat markers: Make a selection, click and hold the Scale Left, Move Right handle for a beat marker, then drag the beat marker. The selected area is scaled, and beats to the right of the selected area are moved. If you click and hold the handle on a downbeat, the preceding bar and the following part of the file are selected. This is useful for correcting tempo detection where the music temporarily slows down or speeds up.

  • To scale all beat markers in the file or region (or in a selection): Click and hold the Scale All handle for a beat marker, then drag the beat marker.

  • To move all beat markers in the file or region (or in a selection) by the same amount: Click and hold the Move All handle for a beat marker, then drag the beat marker left or right.

Apply tempo actions to the file or region in Beat Marker mode

In Beat Marker mode, you can choose the following tempo actions from the Edit menu in the Smart Tempo Editor menu bar:

  • Set Average Tempo for Selection: Sets a single average tempo for the selected area of the file or region.

  • Set Average Tempo within Each Bar: Sets an average tempo within each bar of the selected area of the file or region.

  • Extend First Tempo in Selection to Beginning: Sets the part of the region preceding the selection to use the first (leftmost) tempo in the selection.

  • Extend Last Tempo in Selection to End: Sets the part of the region following the selection to use the last (rightmost) tempo in the selection.

Change the time signature

In Logic Pro, do one of the following:

  • To change the time signature of the audio file or selection: Click the Signature display, then choose a new time signature from the pop-up menu.

  • To add a time signature change at a downbeat: Place the pointer next to a downbeat in the main display, then choose a new time signature from the Signature pop-up menu that appears next to the downbeat.

Changing the time signature replaces any time signature stored in the audio file.

Double or halve the file or region tempo

In Logic Pro, you can change the tempo of the file or current selection:

  • To double the tempo: Click the X2 button in the Tempo display.

  • To halve the tempo: Click the /2 button in the Tempo display.
