Select All ⌘A

Selects all of the “objects” in the currently focused display. All the events. All the regions. Almost all of the channel strips.

Tracks have an entire set of selection commands, with a special case “All” menu item.

Select tracks in Logic Pro — Apple Support

Some track operations, such as duplicating tracks or assigning tracks to a different channel strip, require that you first select the track or tracks.

Channel strips have some different behaviors as well. MIDI channel strips don’t actually contain things, they are simply parameter setting tools.

As long-time Mac user I expect ‘Select All’ to select everything. Clearly in the case of Logic Pro that expectation is unfounded. I must select carefully.

Logic Pro Mixer Question & Click Question Answered | Logic Pro:

I often receive questions from Logic users about various aspects of the program or specific problems. Last week I received two Logic related questions that had straightforward, easily explainable answers that are not immediately apparent unless you know Logic reasonably well. I want to share them here and their solutions, in case they will be of help to others searching for the same information.

As always, Eli Krantzberg’s questions and answers bring nifty tools to light.

  Selection -> Sample Loop

Set the loop points based on the selection.

Selection → Sample Loop: The selected area is used to set the loop start and end points.

Create Loops in the Audio File Editor in Logic Pro — Apple Support

The Audio File Editor Loop commands, available from the Edit menu, are ideal for use with Sampler.

You can also use these functions to generate audio files that contain the loop settings in the file header. This allows you to make full use of these files in any app that can read the loop information in the file header.

  Toggle Hide Group 18

Change the visibility of tracks/channels in group 18.

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.

  Open/Close Audio Insert 10 Plug-in Window of focused Track

Opens or closes the tenth audio insert on the focused track. Unlikely that I would have ten inserts. The key point here is “focused track”. There is no way to toggle the state on all of the selected channels/tracks.

When multiple tracks are selected, the track number of the focused track also appears selected (lighter gray color) on the left edge of the track header, unlike the other selected tracks.
