Chapter 28: Beat Detective 569
Once you are satisfied with the results from Beat
Detective, it is recommended that you flatten
the tracks with the
Consolidate
command. For all
regions selected, Consolidate creates a single,
contiguous audio file to reduce the session’s edit
density. See “Consolidate Command” on
page 506.
Detection (Normal) and
Collection Mode
(Pro Tools HD and Pro Tools LE with Complete
Production Toolkit or Music Production
Toolkit 2 Only)
In some instances, it may be difficult for Beat
Detective to successfully analyze multiple tracks
with the same Detection settings. With Beat De-
tective’s Collection mode, you can collect a set
of beat triggers from different tracks, each with
different Detection settings, and use the collec-
tion of triggers to generate Bar|Beat Markers or
DigiGroove templates, or separate new regions.
Collection mode is the only way to analyze and
create beat triggers on one track, and apply
them to another track.
This method of selectively adding beat triggers
from separate analysis passes on different tracks,
until you get only the triggers you want, is po-
tentially much more effective than manually de-
leting, inserting, or adjusting incorrect or false
triggers.
Drum Tracks and Collection Mode
Suppose you have drum tracks for kick, snare,
hi-hat, and overhead mics. If you analyze a se-
lection across all of the tracks, you may get
many false triggers when you raise the Sensitiv-
ity slider high enough to capture the hi-hat ma-
terial (coming mainly from the tracks for the
overhead mics).
However, if you analyze only the track for the
overhead mics, the resulting beat triggers are
slightly later than the material on the other
tracks (since it will take more time for the sound
to reach the overhead mics). If you then extend
the selection to the other drum tracks and sepa-
rate them, the regions from the kick, snare, and
tom tracks will be cut slightly late (see Figure 31
below).
Using Collection mode, you can analyze each
drum track separately, one at a time, optimizing
the Detection settings for each track until you
get the triggers you want. The triggers for each
track can be added successively to the collec-
tion, or you can choose to collect only the
unique triggers from a track. The collection of
triggers that results can then be used to generate
Bar|Beat Markers or a DigiGroove template, or
separate new regions.
Before consolidating a large selection across
multiple tracks, make sure there is enough
RAM available. See “RAM Requirements for
Beat Detective” on page 550.
Beat Detective LE does not support Collec-
tion Mode without the Complete Production
Toolkit or Music Production Toolkit 2 op-
tion.
