How can you switch the Tempo ruler display between tempo events and Bar|Beat Markers? What happens to existing tempo events when you change to Bar|Beat Markers display?

• A. Use Command-click the add tempo change button (+); existing events convert automatically.
• B. Use Edit > Tempo > Display; existing events are preserved as is.
• C. Use Right-click on tempo ruler and pick the display; existing events are deleted.
• D. Use Preferences > Tempo; existing events are moved to a separate track.

Answer: (A)

You switch the Tempo ruler display by using the tempo-change control and holding the Command key to toggle modes. Specifically, Command-clicking the add tempo change button (+) switches the ruler between showing tempo events and showing Bar|Beat Markers. When you switch to Bar|Beat Markers, any existing tempo events are automatically converted into Bar|Beat markers at the same positions, so the musical timing stays exactly the same even though the representation changes. If you switch back later, the markers convert back into tempo events with the same values.
