Chapter 24: Beat Detective 549
Separating Multiple Tracks
(Pro Tools HD and Pro Tools LE with Music
Production Toolkit Only)
You can use beat triggers from a single track, or
subset of tracks, to separate a group of tracks.
In the following example, the defined selection
is a drum loop consisting of two bars of 5/4. The
kick, snare, hi-hat, and overhead microphones
are recorded to separate tracks.
Analyzing the loop’s kick drum track, with De-
tection Resolution set to Beats, Beat Detective
places beat triggers at the transients on beats 1
and 4 (see Figure 25).
Extending the selection to the snare, hi-hat, and
overhead microphones tracks, and then per-
forming the separation, results in separated re-
gions in each of the drum tracks at the same lo-
cation, based on the beat triggers from the kick
drum track (see Figure 26).
The separated regions can then be conformed as
a group.
You can also utilize Collection mode (Pro Tools
HD and Pro Tools LE with Music Production
Toolkit only) when working with multiple
tracks. Collection mode lets you analyze and de-
tect triggers on tracks individually, and if you
choose, add only the unique triggers from the
current track to the overall collection. For more
information, see “Detection (Normal) and Col-
lection Mode” on page 554.
Beat Detective LE cannot be used across
multiple tracks without the Music Produc-
tion Toolkit option. When Beat Detective
LE (without the Music Production Toolkit
option) is applied to multiple tracks, only
the top track is edited.
