Adapt Project Tempo mode
In Adapt Project Tempo mode, Logic Pro adapts the project tempo to a recording or an
imported audio or MIDI file. When you choose Adapt mode in the Tempo display, the Tempo
track opens so you can see how the project tempo changes after recording, importing
files, or moving regions in the Tracks area. When you make a recording in an empty project
with the metronome off, the project tempo adapts to the recording. During recording, red
lines in the newly recorded region show detected tempo changes. If the metronome is
on, it is used as the tempo reference and the project tempo does not change. The project
tempo does not adapt to subsequent recordings in that part of the project, because the
previous recording provides the tempo reference. If a recording extends beyond that part
of the project, the project tempo adapts to the portion of the region extending beyond the
borders of the first recording.
The project tempo does change to adapt to imported audio or MIDI files. When you move
recorded or imported regions to a different time position, the project tempo at their original
position “follows” them to the new position.
Adapt mode is mutually exclusive with Cycle mode. If the Cycle mode is on when you
choose Adapt in the Tempo display, it is turned off, and the recording starts at the
beginning of the Cycle region.
Important: In general, Adapt Project Tempo mode should be used only temporarily when
making a free recording, when adding a file you want the project tempo to conform to, or
when you specifically want the Tempo track to follow region edits you are making. Because
it results in changes to the project tempo, it should be used with some caution.
Automatic mode
In Automatic mode, Logic Pro determines whether to use Keep or Adapt behavior based
on whether a musical tempo reference is present in the part of the project to which you
record or add audio or MIDI. When a musical tempo reference exists, Logic Pro maintains
the project tempo (Keep mode behavior). When no musical tempo reference exists, Logic
Pro adapts the project tempo to the tempo of audio recordings or imported audio files
(Adapt mode behavior).
When you make an initial recording in an empty project with Auto mode active, the
metronome state determines which behavior is used. If the metronome is on, the project
tempo is preserved as in previous versions of Logic Pro (Keep mode behavior). If the
metronome is off, the project tempo changes to match the recording (Adapt mode
behavior). The project tempo is not changed for any subseqent recordings in the same
range as the first recording, or if files are added or moved in that range, because a musical
tempo reference now exists in that part of the project.
When Auto mode uses Keep behavior, there is no conflict with Cycle mode. When Auto
mode uses Adapt behavior and the Cycle mode is on, it is turned off, and the recording
starts from the beginning of the Cycle region.
