What are the two types of ruler views in Pro Tools?

The correct answer identifies the two types of ruler views in Pro Tools as Time-based Rulers and Conductor Rulers. Time-based Rulers are essential for providing various timing references, which include factors like hours, minutes, and seconds, as well as samples and bars/beats for musical compositions. These rulers help users navigate through projects by offering a visual representation of time which aligns with audio events or MIDI data.

Conductor Rulers, on the other hand, relate to tempo changes and other tempo-related information throughout the session. This ruler is crucial for working with complex musical arrangements where the tempo may change at different points, enabling musicians and engineers to maintain synchronization across tracks.

Understanding the distinction between these ruler types is fundamental for effectively managing sessions in Pro Tools, especially in projects that require detailed timing control and tempo adjustments. This knowledge allows users to manipulate audio and MIDI data more efficiently, creating a more cohesive musical output.
