Quantize timing in the Piano Roll Editor in Logic Pro
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 non-destructively, 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
1. In Logic Pro, double-click a region in the software instrument track that you want to
quantize to open it in the Piano Roll Editor.
2. Select the regions you want to quantize, or select individual notes you want to quantize
in a region.
3. From the Time Quantize pop-up menu, choose the note value you want to use to
quantize the timing of the selected items.
4. To set the degree of quantization, drag the Strength slider left or right.
5. To set the degree of swing, drag the Swing slider left or right.
