Chapter 24: Beat Detective 543
◆ Consider whether lengthy selections should
first be broken down into smaller selections,
which could be more easily managed. For exam-
ple, working in 8- or 4-bar sections might yield
better results more quickly.
◆ Beat triggers are preserved when switching be-
tween audio and MIDI modes. This allows using
MIDI triggers for editing audio, or collecting
triggers from combinations of MIDI and audio
tracks (Pro Tools HD only).
◆ For selections across multiple tracks, consider
whether it may be easier to work with them in-
dividually, or in Collection mode (Pro Tools HD
and Pro Tools LE with Music Production Toolkit
only). See “Detection (Normal) and Collection
Mode” on page 554.
Editing Beat Triggers
Even though Beat Detective offers a great deal of
flexibility in how transients are detected, there
may be times when beat triggers must be de-
leted, moved, or manually inserted. Addition-
ally, triggers can be promoted so they are re-
tained at lower sensitivity settings.
Deleting Beat Triggers
False triggers, which do not represent an actual
beat or sub-beat in the source material, may ap-
pear when raising the Sensitivity slider to detect
quiet material. In these instances you can locate
and manually delete any false triggers.
To delete a beat trigger:
1
With the Beat Detective window open, select
any Grabber tool in the Edit window.
2
Locate the false trigger you want to delete.
Transients for false triggers usually have smaller
peaks than the other trigger points, and typi-
cally fall between the sub-beats.
3
Alt-click (Windows) or Option-click (Mac) the
trigger to delete it.
Moving Beat Triggers
You can adjust the placement of triggers to al-
low for the attack of their transients, or to com-
pensate for an individual transient that is
slightly ahead of or behind the beat.
To move a beat trigger:
1
With the Beat Detective window open, select
any Grabber tool in the Edit window.
2
Locate the beat trigger you want to move and
drag it left or right.
Beat Detective LE does cannot be used
across multiple tracks. When Beat Detec-
tive LE is applied to multiple tracks, only
the top track is edited.
