When dragging a Bar|Beat Marker:
• Its BPM value is recalculated along with the
Bar|Beat Marker to its immediate left. Bar|Beat
Markers to the right of the dragged marker re-
main unchanged.
• Its bar and beat location is dragged with the
Bar|Beat Marker. If the Bar|Beat Marker was
originally placed at 3|1|000, it remains there
(unless it is edited).
• Its sample and SMPTE locations change, as
calculated for by the new tempo for the
Bar|Beat Marker.
• Neighboring MIDI events, along with the
Bars:Beats ruler, shrink or expand as necessary
to adjust for the new tempo.
Editing Bar|Beat Markers
A Bar|Beat Marker can be edited to redefine its
bar and beat location, which also redefines the
start or end point of the range being analyzed
for tempo. This is different from dragging a
Bar|Beat Marker.

Inserting Bar|Beat Markers One at
a Time
Sample-Based Material with Varying Tempos
You can insert Bar|Beat Markers one at a time by
setting an Edit insertion point (instead of mak-
ing a selection) before using the Identify Beat
command. The ability to identify each beat, one
at a time, is especially useful when working with
sample-based material with varying tempos.
For instance, if you have a measure that acceler-
ates slightly, you could insert a Bar|Beat Marker
on each beat (see Figure 15) so the tempo is ac-
curately reflected.
Figure 15. Bar|Beat Markers on each beat
After the Bar|Beat Markers are inserted, further
adjustments in the tempo map are possible by
dragging each of the Markers, as necessary, to
align with the associated beat within the audio.
