MIDI events appear where they sound in the Edit window and the MIDI Editor. However, MIDI events are not actually written to their modified locations until you write the Real-Time Properties to the track or clip. When moving MIDI events, the actual locations (pitch or time) move by the amount the events are dragged, but the effect of Real-Time Properties is displayed. When inserting an event in a track or clip with active properties, Pro Tools takes the properties into account and edits or inserts the event in a different place if necessary to match the effect of the Real-Time Properties.
