Tempo view

Open the Tempo view by using the Views > Tempo command, or by pressing ALT+SHIFT+5.

Figure 679. The Tempo view.

The Tempo view shows the tempo of your project. You can use the mouse to draw tempo changes directly onto the graph.

The Tempo view provides both a graphic display of the tempo and a list of all tempo changes in your project. In the graphical display you can use your mouse to draw tempo changes directly onto the graph. In the tempo list, you can insert, edit, and delete individual tempo changes. Click the Tempo List button to display or hide the Tempo list.

If an entire project has a single tempo, the Tempo view shows a straight horizontal line, and a single tempo in the list.

If you want audio clips to stretch with any tempo changes you introduce, you need to enable Groove clip looping on any audio clips that you want to follow the tempo changes. Do this by selecting one or more clips, right-clicking a selected clip, and choosing Groove Clip Looping from the pop-up menu. Each clip that has Groove clip looping enabled has beveled edges instead of sharp corners. The same command disables Groove clip looping on any selected clip that has Groove clip looping enabled.

Use the global tools to add or modify tempo changes:

Tool	Name	What It’s for
	Select	Drag the Select tool in either the graphic display or the tempo list to select tempos for editing.
	Freehand	Draw a custom curve indicating changes in tempo.
	Line	Draw a straight line indicating a steady increase or decrease in tempo.
	Erase	Eliminate tempo changes already in place for some portion of a project.
	Snap grid	When the Snap to Grid button is depressed, any new tempo changes will only be entered as often as the duration value in the Control Bar’s Snap module.

If you make a mistake using any of these tools, you can use Undo to correct the error. When you use the Draw tool, the speed with which you drag the mouse determines the density of tempo events. To insert a larger number of relatively small tempo changes, move the mouse slowly. To insert a smaller number of relatively large tempo changes, drag the mouse quickly.

The tempo list has its own tools for editing tempo changes:

Tool	Name	What It’s for
	Tempo List	Displaying a list of all tempo changes in the project.
	Insert	Inserting a new tempo change
	Delete	Deleting a tempo change
	Tempo Properties	Editing a tempo change
