  Transpose -1 Octave    ⌥⇧↓

Transpose the rows in the sequencer down an octave.

Logic Pro Step Sequencer overview — Apple Support

Step Sequencer is inspired by classic hardware step sequencers that have rows of configurable switches or knobs used to generate repeating musical patterns. In Step Sequencer, you create patterns by editing multifunctional steps in the step grid. Each row controls either a sound (which can be a drum kit piece, a note on an instrument, or a range of notes) or an automation parameter (letting you create automation changes over time in the pattern). Each step represents a definable length of musical time–by default, steps are of equal length, but you can change the length for individual rows or steps. You can adjust a wide range of parameters for individual steps, including velocity, pitch, gate time, and more; and edit pattern and row settings including pattern length, row loop start and end points, playback position, and rotation.

  Open/Close Instrument Plug-in Window of focused Track

This command replaces the need to click on the Instrument slot of the channel strip to open the instrument. It also saves the need to click the close box to make the window vanish.

Assigning this command to a keypress is highly useful. I have combined it with corresponding ‘Open/Close Audio Insert n of focused track’ so I can quickly pop open the plug-ins.

In Logic Pro, click the center area of the plug-in slot.

  Clean up Project…

I would start with the ‘Consolidate Project’ command –

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.
