What is the purpose of the Quantize function in Pro Tools?

The Quantize function in Pro Tools serves the purpose of aligning MIDI notes to a specific timing grid, ensuring that they conform to the desired tempo and rhythmic structure of a project. This is especially useful in music production to achieve a tighter and more cohesive performance, as it corrects any timing discrepancies that might occur during recording. By applying quantization, users can enhance the precision of their MIDI sequences, making it easier to create a polished sound that fits well within the overall arrangement of the track.

While other functions mentioned, like creating a duplicate of an audio track, mixing down audio tracks, and automatically fixing pitch issues, are valuable tasks in Pro Tools, they do not relate to the specific timing adjustments that the Quantize function provides for MIDI notes.
