  Change Gain…   ⌃G

You can adjust the gain of the audio file, destructively. I use this command whenever I get an audio file that has a maximum gain of 0.0 dB — Logic can’t (or won’t) manipulate this audio in a non-destructive fashion, so I reduce it by .1 dB.

The key command is shared with “Normalize Region Gain” which I use all the time to adjust tracks to have peak values of -9 to -6 dB. The only time this would be counter-productive is when I get multi-tracks of a live performance. In these cases the peaks are performance coordinated. Use the Gain plugin across every track to lower the gain of everything equally — turn down the recording.

  Show/Hide Output Track    ⇧⌘M

Toggles the output track in the Arrange window. I haven’t had an occasion where I thought that I needed this.

  Snap Mode: 1/32 Note

This command only appears to work in the Piano Roll editor. If the command is entered in other editors, or the Arrange window where “Snap” is available the display of the setting will become blank, but the selection doesn’t change. In Arrange Snap will change from ‘Smart’ to ‘Snap to Grid’. In the Piano Roll Snap will change to ‘Snap to Grid’ and the setting will change to 1/32.

I don’t think this is proper behavior, but what do I know?

  Remove DC Offset    ⌃D

I don’t recall ever seeing an audio file with DC on it, but I know how to remove it. Removing DC offset will present a dialog box indicating how much offset is found, and requiring you to confirm removal. In my case all I ever see is 0.00%, so I cancel.

Play audio files in the Audio File Editor — Logic Pro X

Some audio interface hardware can layer direct current (DC) over the audio signal. This results in a vertical shift of the waveform position that can be clearly seen in the Audio File Editor. It can also cause crackling sounds at the start and end of the audio region during playback. Choose Functions > Remove DC Offset to center the waveform around the zero amplitude line.

  Append Track to Track List

Add a new track at the bottom of the Track List (the tracks in the Arrange window).

I can’t find any specific documentation about this.

Experimentally I find that appending a track in a project with MIDI (software instruments, etc.) I get an Instrument track. If I append in a project with strictly audio files I get an audio track.
