Chapter 19 Quantizing MIDI Events 483
Event and Note Quantization
The menu bar of the Piano Roll Editor and Event List offer a Quantization menu and
Quantize button. This is a separate quantization function, which can be applied to
selected events, rather than entire regions.
The Piano Roll Editor also offers a Quantize tool.
Further quantize operations are also available in the Transform window. These can be
applied to events in one or more selected regions that match very specific criteria.
Details in Chapter 20, “Editing MIDI Events in the Transform Window.”
Note: Event-level quantization irreversibly alters the positions of all event types, with
the exception of notes. Note events can be returned to their original record positions.
To quantize events in a region (Piano Roll and Event List):
m Choose the desired quantization value in the Quantization menu.
This menu provides the same grid values available in the Quantization menu of the
Region Parameter box, shown in the Arrange window.
m Do one of the following, dependent on the options available in the window:
 Choose Functions > Quantize Selected Events, or use the corresponding key
command (Score, Piano Roll, and Event List Editors).

A Special Note About Quantization in the Score Editor
The primary purpose of the Score Editor is to produce readable (and printable)
notation. While you can certainly edit MIDI note data in the Score Editor, and quantize
it with the Quantize tool (or Functions > Quantization menu commands), it is best to
perform individual note quantize operations in the Piano Roll or Event List editors.
The Quantize parameter shown in the Inspector of the Score Editor serves a purely
graphical function. It alters the way notes are displayed, but does not affect note
playback in any way.
