Automatically beat map regions in Logic Pro
Logic Pro can automatically beat map audio or MIDI regions using the Beats from Region
command. You can select the note value to use for automatic mapping, and select the
beat-mapping algorithm.
Apply automatic beat mapping
1. In Logic Pro, select the region you want to beat map.
2. Click the title “Beat Mapping” in the Beat Mapping track, and choose Beats from Region
from the shortcut menu.
3. In the Set Beats by Guide Region(s) dialog, choose the note value to use for beat
mapping in the Note Value pop-up menu.
The note value defines the timing resolution used to create the map.
4. Select one of the following algorithms:
Tolerate missing or additional events: Only tempo-relevant transients are used for
beat mapping (based on the project time signature). This avoids drastic tempo
changes, which are usually undesirable.
Note: This algorithm gives the best results when used with material with a regular
beat, and a fairly constant tempo. However, it can also be used with material that
features changing rhythmic divisions, and some degree of tempo change.
Use exactly all existing events: Every detected transient is used for beat mapping.
For usable results, the regions should have an event for each tempo-significant
transient.
5. Click OK to perform the automatic beat-mapping process.
Regions with more complex or irregular musical patterns may not initially produce useful
results with automatic beat mapping. If your first attempt produces an alert saying that
the required tempo would be too low, undo the beat mapping, then set the first downbeat
manually before choosing Beats from Region. If the alert reappears, undo again, and set
both the first and second downbeat manually before choosing Beats from Region. If this
method fails, you can record a MIDI region containing synchronized regular notes, and use
this as a guide region for beat mapping.

Logic Pro and Use beat mapping on audio regions in Logic Pro.
