Create tempo curves in the Tempo track
You can create a continuous transition, or tempo curve, between two tempi using a tempo curve.
Create a tempo curve between two tempi
1 Select the two tempo control points.
2 Click-hold and drag the tip of the right angle line (the corner) above or below the second control
point.
A curve or diagonal line results (a Move Curve Node help tag is shown), which can be dragged—
horizontally or vertically—to alter the curve shape. The process is similar to drawing track
automation curves with the pointer.
Change the resolution of a tempo curve
m Choose a value from the Resolution pop-up menu in the Tempo track to define the number of
tempo changes that are actually performed when using curves.
When set to 1/16, there are four tempo changes per quarter note; 1/1 only generates one tempo
change per bar, which will result in a more abrupt transition. A different resolution can be
defined for each tempo curve.
Delete a tempo curve
m Click the curve node (at the tip of the right angle) with the Eraser tool, or double-click it with the
Pointer tool.
