Tempo Operations Window
The Tempo Operations window lets you define tempo events over a range of time (or measures). The time range is specified in the time format chosen for your Main Time Scale. In addition, the Tempo Operations window lets you:
• Fit a specific number of Bars|Beats into a precise time range.
• Create tempos that speed up or slow down, both linearly and over various curves.
• Scale and stretch existing tempos.

The Tempo Operations window is not available in Manual Tempo mode.
The Tempo Operations window has six pages, one for each type of tempo operation.
• Constant
Lets you create a constant tempo over a selected range of time.
• Linear
Lets you create tempos that change evenly over a selected range of time.
• Parabolic
Lets you create tempos that accelerate or decelerate following a tempo curve that changes the tempo more rapidly or less rapidly over the selection time.
• S-Curve
Lets you create tempos that accelerate or decelerate following a tempo curve with a definable breakpoint that determines mid-curve times and tempo values.
• Scale
Lets you scale tempos within the selection by a percentage amount.
• Stretch
Lets you select a clip of tempo events and apply them to a larger or smaller selection area.
