Logic Pro for Mac tempo overview
Every project has a tempo, which is expressed in beats per minute (bpm). You can set the tempo in the Project Chooser when you create a project, and change it later while you are working. You can set the project tempo in the LCD in the control bar. By default, the tempo for new projects is 120 bpm.
When Enable Complete Features is selected in Logic Pro > Settings > Advanced, you can add tempo changes and control the tempo of a Logic Pro for Mac project in a variety of ways:
Use Smart Tempo to conform audio recordings and imported audio files to the project tempo, or adapt the project tempo to an audio file.
Make quick tempo changes, edit beat markers, and make other tempo edits in the Smart Tempo Editor.
Create tempo changes using the Tempo track or the Tempo List.
Use tempo sets in Logic Pro for Mac to switch between different tempo changes.
Match audio recordings to the project tempo, or match the tempo to an audio region.
Use the Tempo Operations window and Tempo Interpreter window for more complex control of the project tempo.
Control tempo changes using the tempo fader in the Environment.
