Given this behavior, you should avoid making changes in the Tempo track after using<br />

Beat Mapping functions. If you do so, the timing derived from the Beat Mapping functions<br />

will be destroyed. For more information about the Beat Mapping track, see Beat Mapping<br />

Recording Tempo Changes in <strong>Logic</strong> <strong>Pro</strong><br />

All tempo changes made when <strong>Logic</strong> <strong>Pro</strong> is in record mode are automatically stored as<br />

tempo events on the Tempo track. These events can be created with external MIDI<br />

controllers, the Environment tempo fader, or external synchronization signals. You can<br />

edit recorded tempo events in the Tempo track or using one of the tempo editors—Tempo<br />

List, Tempo Operations window, Tempo Interpreter window, or Tempo fader.<br />

To enable tempo change recording<br />

1 Open the Recording project settings by doing one of the following:<br />

• Choose File > <strong>Pro</strong>ject Settings > Recording (or use the Open Recording <strong>Pro</strong>ject Settings<br />

key command, default assignment: Option-*).<br />

• Click the Settings button in the Arrange toolbar, and choose Recording from the pop-up<br />

menu.<br />

• Control-click (or right-click) the Record button in the Transport bar, and choose<br />

Recording Settings from the pop-up menu.<br />

2 Select the “Allow tempo change recording” checkbox.<br />

Adjusting the Tempo to Fit Audio Regions<br />

The Options > Tempo > Adjust Tempo using Region Length and Locators command<br />

adjusts the project tempo by creating a tempo change event at the start point of the<br />

selected audio region. This ensures that the length of the selected audio region matches<br />

exactly the distance between the locators.<br />

For more information on this function, see Setting the <strong>Pro</strong>ject Tempo to Match an Audio<br />

Region.<br />
