Use Smart Tempo
Logic Pro Smart Tempo overview
Smart Tempo brings powerful new tempo analysis and editing capabilities to Logic Pro.
With Smart Tempo you can record a performance without the metronome and have Logic
Proadapt the project tempo to match the tempo of the recording, or keep the project
tempo and flex the recording to match it. Smart Tempo also makes it easy to create remixes
using audio files and MIDI regions with different tempos that all conform to the project
tempo, or adapt the project tempo to the tempo of an imported audio file or MIDI region.
To use Smart Tempo, you choose the Project Tempo mode to set the overall tempo
behavior for the project, and use the Flex & Follow setting for individual audio regions to
set how they interact with the chosen Project Tempo mode.
Unlike audio quantization, which identifies transient peaks in an audio file, Smart Tempo
analysis places beat markers based on the musical tempo detection of an audio file. When
used with complex musical material, Smart Tempo analysis can deliver better results
(particularly when Flex & Follow is set to Bars or Beats) than using audio quantization.
Though transients can be edited destructively in the Audio File Editor, you edit Smart
Tempo beat markers and other tempo information in the Smart Tempo Editor.
You can also use Smart Tempo with MIDI regions in a project. MIDI regions always follow
the project tempo, and so behave similarly to flexed audio files with the Flex & Follow
region setting set to On. Because MIDI regions have no source audio file, the Smart Tempo
analysis and any edits you make in the Smart Tempo Editor are saved directly to the MIDI
regions and stored with the project.
