Which of the following is a type of cursor available in the Edit Window of Pro Tools?

The playback cursor in Pro Tools is a critical element within the Edit Window, serving as the visual representation of the point in time where audio playback is occurring. This cursor helps users navigate through their sessions, allowing them to monitor the progress of their project in real-time. It moves along the timeline as the session plays back, giving a clear indication of where the audio currently is and providing a frame of reference for editing or making adjustments.

While other cursor types like the paint cursor and automation cursor serve specific functions related to their respective tools, they do not provide the same fundamental playback functionality that the playback cursor does. The mix cursor, on the other hand, is not a standard tool or representation used within the Edit Window, further highlighting the unique role of the playback cursor in the Pro Tools environment. This essential functionality of the playback cursor makes it a pivotal tool for users during mixing and editing processes.
