Quantize the timing of notes in the Piano Roll Editor
You can quantize, or automatically correct, the timing of individual MIDI notes in the Piano Roll
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.
