Clean up Project…

I would start with the ‘Consolidate Project’ command –

Consolidate assets in a Logic Pro project — Apple Support

Using the Consolidate command, you can create a “consolidated” copy of a project, and select which types of assets are copied into the consolidated project.

Clean up project files

1. In Logic Pro, choose File > Project Management > Clean Up.
2. In the dialog that appears, select the checkboxes for the cleanup options you want to apply to the current project.
   • Delete Unused Files: Files not used in any project alternative are deleted from the project, and removed from the Project Audio Browser.
   • Note: Selecting Delete Unused Files will also select Delete Backups.
   • Delete Backups: Backups for all project alternatives are deleted from the project.
3. Click OK.
4. A dialog appears, showing all of the files to be deleted from the project. To keep any individual files from being deleted from the project, deselect the Delete checkbox for those files.
5. Click OK.

  Delete Selected Audio File Group(s)

Remove the grouping of the audio files. The files are not deleted. The group is deleted.

You cannot delete a group that is based on file attributes or selected regions, choose a different grouping mechanism.

Sort, group, and rename audio files in Logic Pro — Apple Support

Select the files you want to group, choose View > Create Group, enter a name in the Name field, then press Enter.

Select the files you want to group, then choose one of the following from View > Group Files by:

• Location: Creates groups that are alphabetically sorted by the names of the parent folders of selected files. Folder names are automatically used as group names.
• File Attributes: Creates groups based on the attributes of selected files (file type, stereo/mono, bit depth). Group names are displayed as a summary of the file attributes—16 bit Mono AIFF, for example).
• Selection in Tracks: Creates groups based on regions selected in the Tracks area. Group names are based on the first of the selected regions.

  Create Lane    ⌥⌘N

The comparison between lanes in the Step Editor and tracks in the Tracks area is helpful.

The Step Editor should not be confused with the Step Sequencer.

The Step Editor allows you to create detailed editing windows for MIDI events that can contain lots of details that need to be attended to.

Logic Pro Step Editor Overview — Apple Support

Lane: Each MIDI event type, be it a note or MIDI controller, is arranged from top to bottom in horizontal lanes much like the track lanes shown in the Tracks area. The type of event shown, and controlled, on each lane is freely configurable. You do this by setting Lane parameters (for each lane) in the inspector. For more information, see Logic Pro lane parameters overview.

  Enharmonic Shift: #    ⇧3

Change the notation for the current note(s) to the enharmonic spelling using sharps. A rare occurrence, but sometimes necessary.

Change how accidentals appear in a score in Logic Pro — Apple Support

By default, the display of accidentals depends on the chosen key signature. Using note attributes, you can change flats to sharps, and vice versa. For information about setting the key signature, see Add key and time signature changes to a score in Logic Pro.
