MIDI Regions and Events MIDI regions, by comparison, 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 as part of the project. MIDI region MIDI note events MIDI controller events The MIDI data events stored within MIDI regions include note, controller, program change, and other information. These data events represent MIDI performances that you have recorded into Logic Express. MIDI performances are generally created with a MIDI keyboard, but can also 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 includes: transposition, quantization (timing correction, which is similar to the spell checker of a word processor, when dealing with the language of music), timing delays, and more. You can also edit individual events within a MIDI region. You do this by opening the region in one of the MIDI editors. These windows 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 freely enter MIDI data with your MIDI keyboard, the mouse, or computer keyboard in these editors.
