Using the Tempo view

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. To open the Tempo view, choose Views > Tempo or press ALT+SHIFT+5. Click the Tempo List button to display or hide the tempo list.

Figure 95. The Tempo view

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

The Control Bar contains several tools you can use to add or modify tempo changes:

Table 59.  

Tool	Name	What it’s for
	Select	Drag the Select tool in either the Tempo list or graphic display to select tempos to edit
	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	Controls how often you can insert tempo changes—for example, every measure, every eighth note, every 3 samples, etc.

If you make a mistake using any of these tools, you can use Edit > Undo to correct the error. When you use the Freehand 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 Pane has its own tools for editing tempo changes:

	Insert Tempo	Insert a new tempo change
	Delete Tempo	Delete a tempo change
	Tempo Properties	Edit a tempo change
