Quantize the timing of notes in the Score Editor
You can quantize, or automatically correct, the timing of individual MIDI notes in the Score Editor. This is useful when regions in the track contain the right notes, but are not perfectly in time with the project. When you quantize the timing, items are adjusted to the selected note value. You can quantize the timing of regions with drums, single-note instruments, and chordal or polyphonic instruments.
The Time Quantize controls quantize notes and other items nondestructively, for playback only. The original timing is never lost, and can be recalled by setting the value to off.
Time quantization in the Score Editor works in the same way as time quantization in the Piano Roll Editor. In the Score Editor, you can also visually quantize the display of notes (independent of their MIDI time quantization) in the Region inspector. For information about visual quantization, see Quantize.
