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.

From the Time Quantize pop-up menu, choose the note value you want to use to quantize the timing of the selected items.
To set the degree of quantization, drag the Strength slider left or right.
To set the degree of swing, drag the Swing slider left or right.
