Reactivate Upbeat Event Playback — Logic Pro X keyboard command of the day

  Reactivate Upbeat Event Playback

Nothing in the documentation…zip

Closest thing I found was in a Reddit conversation –

– There is a new menu item “Reactivate Upbeat Event Playback” to allow MIDI notes that are ¼ note or less before the start of a region to play, in cases where the left edge of the region has been edited.

but I should have read the release notes — the reddit post is the release notes.

The command is in the contextual MIDI menu in the tracks area. If you modify a MIDI region the command becomes active.

My assumption is that if I modify a region causing an upbeat event to be “removed” this command will cause the region to include the upbeat if it is there.
