Understanding the Quantize Grid Options

You can quantize selected audio or MIDI regions, including a selection of both, by changing the value of the Quantize parameter in the Region Parameter box of the Inspector. This parameter determines the division of the quantization grid.

Important: The region Quantize parameter is nondestructive. It adjusts the playback positions of notes in the region on-the-fly when Logic Express is in Playback or Record mode. It does not actually move the notes permanently.

The settings in the Quantize pop-up menu in the Region Parameter box of the Inspector can be roughly grouped into the following categories:

The Swing settings delay the position of every second point in the quantization grid by a fixed percentage, as follows:
