Tempo Operations
Pro Tools provides several commands for defin-
ing tempo events over a range of time (or mea-
sures).
Tempo Operations Window
This command opens the Tempo Operations
window. This window lets you define tempo
events over a range of time (or measures) by
choosing any of the following commands from
the pop-up menu at the top of the window:
•Constant
•Linear
• Parabolic
•S-Curve
•Scale
•Stretch
Constant
This command lets you create a constant tempo
over a selected range of time.
Linear
This command lets you create tempos that
change evenly over a selected range of time.
Parabolic
This command lets you create tempos that accel-
erate or decelerate following a tempo curve,
which changes the tempo more rapidly or less
rapidly over the selection time.
S-Curve
This command lets you create tempos that accel-
erate or decelerate following a tempo curve with
a definable breakpoint that determines mid-
curve times and tempo values.
Scale
This command lets you scale tempos within the
selection by a percentage amount.
Stretch
This command lets you select a group of contig-
uous tempo events and expand or compress
them into a larger or smaller selection area.
