Use Smart Tempo with remixes
When creating a remix, you often work by combining files recorded at different tempos,
and that may contain tempo changes. With the Project Tempo mode set to Keep, imported
files do not affect the project tempo.
Imported audio files conform to the project tempo, as long as their Flex & Follow parameter
is not set to Off. By setting the Flex & Follow parameter for the audio regions to Bars or
Bars and Beats, beat markers are additionally used to conform them at the bar or beat
level. The audio regions from the files can be transposed as needed so they play back in
the same key. Any audio regions with their Flex & Follow parameter set to Off keep their
original tempo, and do not conform to the project tempo. MIDI regions always follow the
project tempo.
Use Smart Tempo with existing projects
You can use Smart Tempo with existing projects, including projects created in an earlier
version of Logic Pro. For most projects, the workflow described in Use Smart Tempo with
mulitrack audio files in Logic Pro is recommended, because it allows you to define which
audio files contribute to the Smart Tempo analysis, and allows the analysis results to be
shared between all audio files. In cases where you do not want the Smart Tempo analysis
results to be shared across audio files, and in which the project contains a single region
having a clearly audible and consistent rhythmic pattern throughout (for example, a stereo
recording of the overhead mics of a drum kit), you can use the following workflow:
After opening the project, make sure the Project Tempo mode is set to Keep, and open
the audio file corresponding to the rhythmic region in the Smart Tempo Editor. Turn on
the Smart Tempo Editor metronome and audition the file to verify that the Smart Tempo
analysis is correct, making any needed edits. After verifying and correcting the region,
choose Apply Region Tempo to Project Tempo from the Edit pop-up menu (or Control-click
the region in the Tracks area and choose the corresponding command from the shortcut
menu). In the dialog, make sure both the “Align downbeat to nearest project downbeat” and
“Maintain relative position of all other regions” checkboxes are selected, then click Apply.
This writes the analyzed tempo from the selected region to the Tempo track, aligns the
selected region to the downbeat, and maintains the relative positions of the other regions
(as well as other data such as automation curves) to the analyzed region. Using this
workflow, tempo-synced regions (such as Apple Loops or Drummer regions) and effects
added to the project also conform to the project tempo.
Choose the Project Tempo mode in Logic Pro
The Project Tempo mode determines whether the project tempo is maintained, or adapts
to the tempo of recordings and imported audio or MIDI regions. Each mode is useful for
different situations, as described in the following sections:
Keep Project Tempo mode
In Keep Project Tempo mode, Logic Pro maintains the project tempo. When you make a
recording or move regions to a different time position, the project tempo does not change.
You can use Logic Pro functions, including the metronome and Cycle mode, the same as
with earlier versions of Logic Pro. Audio recordings and imported audio files conform to the
project tempo as long as their Flex & Follow parameter is set to On, On + Align Bars, or On
+ Align Bars and Beats.
