Create Backup ⌃B – Logic Pro keyboard command of the day

  Create Backup ⌃B

Create a backup copy of the current audio file. The Audio File Editor performs destructive edits which cannot be “undone”. Reverting to the backup copy is the only way to undo the edits.

The Project Audio Browser has a command – Backup File(s) – which uses the same keyboard mapping. Files backed up have the same ‘.dup’ extension as they do when backed up in the Audio File Editor.

In Logic Pro, choose Audio File > Create Backup from the Audio File Editor menu bar (or press Control-B).
A copy of the audio file (with the extension .dup) is created in the same folder as the source file.

Set Region Anchor to Playhead – Logic Pro keyboard command of the day

  Set Region Anchor to Playhead

It is difficult to find a definition of “region anchor”. The simplest visible sign is the anchor indicator that you see in the Project Audio Browser. Typically a region anchor is at the start position of the region, but it can be moved.

The anchor can be used when regions are moved. If I set the region anchor to the middle of a region I can move the region to a different location typically placing the region anchor position at the playhead position.

If more than one region is selected, all subsequent regions are moved. For audio regions, the region anchor is placed at the current playhead position.

I have still not found a decent description of “the Anchor” and how it is used…the best that I can discover is that the anchor is what gets aligned to the playhead when adding regions to tracks.

Someday I will edit audio in Logic.

 Map performance patches in Logic Pro – Apple Support

Performance patches can also exhibit interesting characteristics that differ when playing live and when playing back a region. When you play a note live on the keyboard, the sample is played from the sample anchor—a marker that represents the musical focus of the sample, or the position that should land on a beat. When you play back recorded MIDI events, however, the full sample is played, even if it starts before the note on event. This behavior leads to more natural-sounding instruments—for example, the sound of a tambourine that is generated before the actual palm hit.
