Close Project ⌥⌘W — Logic Pro keyboard command of the day

  Close Project    ⌥⌘W

Close the current project. If there are any unsaved changes Logic will prompt you to save the changes.

‘Close Project without saving’ is ⌃⌥⌘W

Save Logic Pro projects — Apple Support

Logic Pro autosaves your work so that you don’t lose important changes if the app quits unexpectedly. Logic Pro shows a dialog when you reopen the project, asking if you want to use the autosaved version. If you choose not to, Logic Pro opens the last manually saved version of the project.

Toggle Hide Group 39 — Logic Pro keyboard command of the day

  Toggle Hide Group 39

Toggle between showing and hiding channels in group 39. This command is defined, but does not exist. There are currently only 32 groups possible (Logic Pro 10.6.1)

Overview of groups in Logic Pro — Apple Support

Prior to mixing, you may find it useful to define some logical channel strip groups. You could, for example, group all drum channel strips under one drum group. This would allow you to control the group meters (volume, pan, mute, solo, sends, and so on) using a single control, while still maintaining the relative parameter values of each channel strip.

Rename Track Alternative by Selected Region — Logic Pro keyboard command of the day

  Rename Track Alternative by Selected Region

Name the current track alternative with the name of the selected region.

Handy way to keep the arrangement window clear and informative.

Track alternatives were not available when I first started using Logic. Not being a person to “comp tracks” the whole process seemed opaque. I need to investigate the use of track alternatives as opposed to alternative versions of a project.

Use track alternatives in Logic Pro — Apple Support

You can create and edit track alternatives and switch between them. Each alternative can contain different regions or arrangements, while sharing the same channel strip and plug-ins. Track alternatives are like “playlists” for individual tracks that can be used to try out different ideas or archive tracks at different stages of development.

Set Nudge Value to Sample ⌃⌥S — Logic Pro keyboard command of the day

  Set Nudge Value to Sample    ⌃⌥S

Sets the nudge value to a sample.

This allows for extremely fine adjustment to the location of audio. One practical application would be to adjust bass tracks that were recorded with a DI and with a microphone on the amplifier. The DI signal will sound sooner than the amped signal. This typically doesn’t sound so good. Adjusting the DI track forward by a few samples (or move the amped track backward) can make the sound much better.

If multiple instruments were captured by microphones at the same time I would move the DI forward. If it’s only the bass tracks it doesn’t matter which one you move.

NB check the phase of the two signals. Flipping the phase can make an enormous difference in the sound.

Move regions in the Logic Pro Tracks area — Apple Support

You can nudge regions (move them in small increments) left or right using key commands. To nudge regions, you first set the nudge value, then move selected regions by this value. Alternatively, you can nudge regions by a set value.

Rotate Left by Nudge Value ⌃⌥⌘← — Logic Pro keyboard command of the day

  Rotate Left by Nudge Value    ⌃⌥⌘←

Rotate the contents of the selected region to the left.

Rotating an audio region seems like such an odd thing to do, unless you’re making beats or constructing music. It certainly can make for some interesting sounds,

Move regions in the Logic Pro Tracks area — Apple Support

You can also rotate regions. Similar to slipping, rotating moves the region content left or right by the nudge value, but with the difference that content that extends past the region border on one side reappears on the other side, as though the region were a loop.

When an audio region is rotated, it is converted to a one-track folder (indicated by a folder icon in the upper-left corner of the region) containing two regions. If it is rotated multiple times, the number of regions in the one-track folder stays the same, but the junction point between the two regions moves through the folder, reflecting the extent of the cumulative rotation. You can unpack the one-track folder, or unpack and merge it to a single region, by clicking the folder icon and choosing corresponding commands from the menu that appears.
