All of the following are ways to suspend automation, except:

• A. Click the Suspend button in the Automation window
• B. Command-click on the Track View Selector (when displaying automation)
• C. Set the track's Automation Mode selector to Off
• D. Command-click on the track's Automation Mode selector

Answer: (D)

Suspending automation makes Pro Tools ignore the automation data during playback, so the track plays without those automated changes until you resume. The suspend function is meant to give you a quick, temporary override of automation.

Using the Suspend button in the Automation window is a direct, explicit way to stop automation from influencing playback. You can also quickly suspend for a specific track by Command-clicking the Track View Selector while automation is displayed, which toggles the suspension for that view. Setting the track’s Automation Mode selector to Off also stops automation from being read or written for that track, effectively suspending it.

Command-clicking on the track’s Automation Mode selector, however, is not a method to suspend automation. This action is used to access or toggle between automation modes directly, not to suspend automation playback.
