Select Next Take or Comp   ⇧⌘↓

Selects the next take or comp from a take folder.

Preview take recordings in Logic Pro — Apple Support

In order to create and edit comps, you first need to preview the take recordings in a take folder. The simplest way to preview take recordings is to open the take folder. You can then select the individual takes for playback. You can also select and preview takes in a closed take folder.

  Convert Repetitions to Loops

If you have multiple, identical MIDI regions in sequence you can convert them to be a loop with multiple repeats.

If you copy an audio region and repeat it multiple times in a row you can convert them to be a loop. I’m not sure if this is useful or not.

Loop regions in the Logic Pro Tracks area — Apple Support

You can loop regions so that they play repeatedly, and extend them to fill any amount of musical time in the Tracks area. When you play the project, the region repeats the number of times you have extended (looped) it.

  Import Audio File…    ⇧⌘I

Add a new file to the project. I should experiment with deleting unused sections from audio files. I have lots of tracks that are less than 30% “populated”.

Add and delete audio files in Logic Pro — Apple Support

When you add an audio file to your project, Logic Pro automatically creates a region that encompasses the entire file length. You can create as many regions as you like from the same audio file. There are no length limitations to regions, as long as they don’t exceed the length of the source audio file. Creating multiple regions from the same audio file is beneficial for many tasks—using different portions of a vocal take that spans the length of the project, for example.

You can delete audio regions and audio files in the Project Audio Browser. In addition to deleting unused audio files, you can also delete unused portions of audio files. This usually frees up a lot of space on the hard disk.

  Move Selection with First Transient to Nearest Beat

Align selections to the beat.

Use beat mapping on audio regions in Logic Pro — Apple Support

In Logic Pro, Control-click the beat mapping header, then choose Move Selection with First Transient to Nearest Beat from the shortcut menu (or use the corresponding key command).

The first transient marker in the region selection is moved to the nearest whole beat position, with all selected regions moving with it.

Logic Pro beat mapping overview — Apple Support

When Advanced Editing Options is selected in the Advanced preferences pane, you can access the Beat Mapping track. Beat mapping lets you map notes that don’t follow a strict tempo with beats in the ruler. When you play the project, the project tempo adjusts so that the beat-mapped notes are aligned with beats in the ruler.

  Select And Operate using Transform User Preset 27

Select the MIDI events and transform them using preset 27. Lots of un-named programs.

Use MIDI transform sets in Logic Pro — Apple Support

Depending on your needs, it may be worthwhile to create your own transform sets. These can be configured and saved as part of a project. (Doing this in your template projects makes your transform sets available in all projects.) Your transform sets are shown at the bottom of the Presets pop-up menu.
