View multiple regions in the Piano Roll Editor in Logic Pro for Mac

You can view the contents of several selected MIDI regions, all MIDI regions in a folder, or all MIDI regions in a project using Link modes.

When multiple MIDI regions are displayed in the Piano Roll Editor, you can freely select note events from different MIDI regions, and edit them. A help tag indicates the number of selected events and their parent MIDI regions. For example, 8/2 means that eight notes are selected from two MIDI regions.

When viewing multiple MIDI regions, you can temporarily display only the region of a note by double-clicking the note.
