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.
Quantize the timing of notes in a MIDI region
Do one of the following:
In the Tracks area, select the MIDI regions you want to quantize.
In a MIDI region, select the individual notes you want to quantize.
From the Time Quantize pop-up menu, choose the note value you want to use to quantize the timing of the selected items.
Drag the Strength slider to the left to decrease the strength of quantization.
The Strength slider is available when MIDI regions are selected, but not when individual notes are selected.
