• If the selection’s tempo and meter match
the session tempo and meter (see “Calcu-
lating Tempo with Beat Detective” on
page 337), and it aligns correctly with the
session’s bars and beats, click the Capture
Selection button. The correct Time Signa-
ture, and Start Bar|Beat and End Bar|Beat
values will be filled in automatically.
4 To improve Beat Detective’s accuracy in ana-
lyzing swung notes, select the Contains option
that indicates the smallest sub-division of the
beat contained in the selection. The Contains
options include eighth-note, sixteenth-note
(the default setting), thirty-second-note, and
triplet modifier. In Pro Tools 6.x, the selected
Contains option determines the groove tem-
plate grid locations for DigiGroove templates.
