m Click at the desired position with the Pencil tool.
Keep an eye on the help tag when using the Pencil tool, and don’t release the mouse
button until the intended tempo and position are indicated. No help tag appears when
the Pointer double-click method is used.
m Hold Control-Option-Command and click at the desired position in the Tempo track.
A text field opens, allowing you to type in the desired bpm value. Press Return, and a
tempo event of this value will be created.
To delete a tempo change, do one of the following:
m Select it, by either clicking the node itself or the line to the right, then choose Edit >
Delete (or press Backspace).
m Double-click on the node with the Pointer Tool.
m Click on the node with the Eraser tool.
Creating Tempo Curves
To create a continuous transition between two tempi, click-hold and drag the tip of the
right angle line (the corner) above or below the second node.
A curve or diagonal line will result (a Move Curve Node help tag is shown), which can
be dragged as desired—horizontally and vertically—to alter the curve shape. You’ll find
that this is quite similar to drawing track automation curves with the mouse.
To make a tempo curve more, or less, precise:
m Choose the desired 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.
