Which aspects does the Playback Engine control in Pro Tools, and where is its settings panel located?

• A. It controls MIDI routing; Setup > Preferences.
• B. It controls hardware I/O, buffer size, CPU usage, and related performance options; Setup > Playback Engine.
• C. It controls clip gain; Edit > Clip Gain.
• D. It controls project tempo; Setup > Tempo.

Answer: (B)

Playback Engine is the part of Pro Tools that governs how the software interacts with your computer’s audio hardware and how much processing power it can use. It centralizes performance-related controls, such as selecting the hardware I/O, adjusting the hardware buffer size (which affects latency versus CPU load), and other CPU/performance settings that influence real-time playback and stability. That’s why this panel is located under Setup > Playback Engine. In contrast, MIDI routing belongs to the MIDI setup, clip gain is edited in the Edit window, and tempo is set in the Tempo settings.
