Quantize the timing of notes

Quantize the timing of notes in the Piano Roll Editor

You can quantize, or automatically correct, the timing of notes in MIDI regions. This technique 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, chordal or polyphonic instruments, and other material.

You can select and quantize complete MIDI regions, or quantize only selected notes in a MIDI region, using the Time Quantize pop-up menu.

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.
