Object Width +1 Pixel  ⌥⇧→

Change the size of the selected object — make it one pixel wider.

In the days of retina displays and massive numbers of pixels it remains unclear about how useful this is. A 19 inch screen that is 1024×768 pixels has a pixel count of approximately 100 per inch. My Retina 5K iMac (5120×2880) is closer to 320 pixels per inch. My eyesight can’t distinguish a single pixel difference in dimension anymore.

Adjust position, size of objects in the Logic Pro Environment — Apple Support

Objects can be freely placed, which allows for flexibility, but can lead to overlaps or misalignments—particularly when pasting between layers. Fortunately, you can quickly clean up object positions.

  Make Alias

Create an alias to the currently selected MIDI region(s). Some days commands come back to back. Yesterday was ‘Delete All Orphan Aliases’.

Create MIDI aliases in the Logic Pro Tracks area — Apple Support

If several regions are selected, their relative time and track positions are retained. The selected track is the destination track for the first region along the Tracks area.

  Delete All Orphan Aliases

Deletes orphaned aliases. An orphaned alias is an alias (looks like a MIDI region) to a MIDI region. If the original region is deleted, and you have Logic keep the aliases around, you will have orphaned aliases.

I created an alias, deleted the original region, then unsure the ‘Delet All Orphan Aliases’ command. There is, apparently, no undo of this action.

Create MIDI aliases in the Logic Pro Tracks area — Apple Support

You can create an alias for a MIDI region or a folder. An alias is a reference to a region, and looks similar to a normal region in the Tracks area. If you alter the original region, all aliases of the region are similarly altered.

Aliases can be useful when you want to repeat a phrase or riff in different parts of an arrangement. If you make changes to the original region after creating aliases from it, the changes apply to all its aliases throughout the project. If you want to edit one of the aliases without changing the others, you can turn that alias into an independent region (a region copy) and edit it independently.

Aliases do have some differences from their “parent” region: you can give each alias its own name, and edit region parameters for each alias independently.

Alias names appear in italics to distinguish them from normal regions. If you name an alias, its parent region name is shown below the alias name (provided that the zoom level is adequate).

  Toggle Fix Value

Toggle the use of fixed value when creating steps.

Create steps in the Step Editor in Logic Pro — Apple Support

You can assign a fixed value when creating event steps. When enabled, the Fix Value item in the Lane Set pop-up menu prevents any event value from being altered with the Pointer or Pencil tool.

It might be useful to read some of the Logic Pro 9 manual describing the Hyper Editor (Step Editor in X) for a discussion of ‘fix value’ and other nuanced behaviors…

You can also assign a fixed value when creating events. The Fix Value checkbox in the Inspector, when selected, prevents any event value from being altered with the Pointer or Pencil tool.
