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 avail-
able in Manual Tempo mode.
