There are a number of ways to improve the beat mapping accuracy of audio regions. When you
choose Analyze Transients, those transients above a certain threshold are displayed. You can
adjust the threshold using the Minus and Plus (–/+) buttons in the Beat Mapping track.
Increasing the number of transients can be useful when beat mapping regions with less distinct
accents—such as soft drums in a loud mix. However, a high setting can result in extraneous
transients, with no real meaning for the rhythmic structure, being displayed. In general, it’s better
to begin with a lower setting, and move to a higher setting only if transients are missing for
obvious rhythmic elements in the music.
Sometimes, your MIDI recordings may contain note events that fall on musically meaningful
positions, and should not be affected by beat mapping applied to audio recordings. In this
case, you can choose the Protect MIDI option to keep existing MIDI events at their current ruler
positions when beat mapping audio regions.
You can also make beat mapping easier by moving one or multiple selected audio regions, so
that the first transient marker in any of the regions is located on the nearest whole beat position.
Change the threshold of transients displayed
Do one of the following:
m
To decrease the number of transients displayed: Click the Minus button (−) in the header of the
Beat Mapping track.
m
To increase the number of transients displayed: Click the Plus button (+) in the header of the Beat
Mapping track.
Protect MIDI events from being beat mapped
m
Click the title “Beat Mapping” in the Beat Mapping track, then choose Protect MIDI from the
shortcut menu.
Move the first transient marker in a region selection to the nearest whole beat position
m
Control-click the beat mapping header, then choose Move Selection with First Transient to
Nearest Beat from the shortcut menu (or use the corresponding key command).
The first transient marker in the region selection is moved to the nearest whole beat position,
with all selected regions moving with it.
