Chapter 12 Getting to Know Regions 293
MIDI Regions and Events
MIDI regions actually contain MIDI data events. They are not related to information
stored in external files. MIDI regions can be saved as individual files, but they can also
be, and generally are, stored with the Logic project.
The MIDI data events stored within MIDI regions can include; note, controller, system
exclusive, and other information. These data events represent MIDI performances that
you have recorded or imported into Logic Express. MIDI performances are generally
created with a MIDI keyboard, but can certainly be generated with MIDI controllers,
MIDI guitars, your computer keyboard or the mouse.
MIDI data events can be affected as a group by processing the MIDI region that
contains them. Such processing—which takes place in the Inspector Region Parameter
box—includes; transposition, quantization, timing delays, and more.
You can also edit individual events within a MIDI region. This is achieved by opening
the region in one of the MIDI editors available in Logic Express. These editors allow you
to precisely alter the position, length, and pitch of MIDI note events. Other MIDI event
types can also be altered in various ways. You can also enter MIDI data with your MIDI
keyboard, the mouse, or computer keyboard in these editors.
