der to use it in other sessions or share it

click Save. (Do not change the location of
DigiGroove template files and folders or

Swing Content for Generating Groove
Templates
When defining swing content of the selection,
select the Contains eighth-note option if the au-
dio selection has a heavily swung eighth-note
groove. If the audio selection has relatively
straight eighth-notes, use the Contains six-
teenth-note option. This lets the resultant Digi-
Groove template be applied more easily else-
where. Although a groove might be based upon
non-swung eighth-note material, you might
want to apply the template to material that con-
tains sixteenth-notes. If a template only has
eighth-note resolution, but the material being
conformed contains sixteenth-notes, adjacent
sixteenth-notes will be mapped to the same
eighth-note location.
Groove Extrapolation
Beat Detective’s ability to extract tempo data
from a wide range of material is enhanced by its
powerful “groove extrapolation” logic. Groove
extrapolation automatically generates beat trig-
gers for inclusion in groove templates even if a
peak transient is not detected. For example, a
drum loop might not have a hit on beat 3, con-
sequently no peak transient is detected and no
beat trigger is generated. Beat Detective will ex-
trapolate from other beat triggers in the selec-
tion and create a trigger for beat 3 in the groove
template.
In addition, extrapolated triggers preserve the
feel of triggers generated from detected peak
transients. For example, if a bar of kick drum de-
tected three beat triggers, all of which were 20
ticks ahead of the beat, any extrapolated beat
triggers will also be mapped 20 ticks ahead of
the beat.
Extract Groove Template dialog
Use folders and subdirectories to organize
DigiGroove templates. However, be sure
they are always located in C:\
Program Files\Digidesign\Pro Tools\
Grooves (Windows) or Applications/
Digidesign/Pro Tools/Grooves (Mac).
Groove template files located elsewhere will
not be available in either Groove Quantize
or Beat Detective.
