Overview of MIDI region editing in the Tracks area in Logic Pro for iPad
The parameters you change when editing MIDI regions in the Tracks area are playback parameters. That means the MIDI notes inside the regions are not altered, and only an offset value is applied while playing back the region.
Basic editing tasks for MIDI regions
The basic editing tasks for regions in the Tracks area also apply to MIDI regions:
MIDI region–specific editing tasks
The basic region editing tasks performed in the Tracks area only affect the region (that contains the data), and the editing tasks performed in the Piano Roll Editor affect the “content,” the MIDI data inside the region. However, the following parameters (available in the Region inspector when you select a MIDI region in the Tracks area) change the data inside the MIDI region, the MIDI notes. The Transpose parameter, for example, will not change the pitch of the note events and only applies a pitch offset during playback, but other parameters in the Region inspector, such as Quantize, will overwrite any edits you have made in the Piano Roll Editor.
