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
deleting, 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 21
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.
Using Collection Mode
Collection mode is available in Bar|Beat Marker
Generation, Groove Template Extraction, or Re-
gion Separation mode, and is accessed by click-
ing the Collection Mode button in the Detec-
tion section.
To use Collection mode:
1 In the Edit window, make an audio selection
on a single track. Make sure the selection’s start
and end points fall cleanly on the beat.
2 In the Beat Detective window, select one of
the following modes:
• Bar|Beat Marker Generation
• Groove Template Extraction (Pro Tools 6.x
only)
• Region Separation
