Quantize 1/8 Note

Set quantization to an eighth note. Selecting a group of notes with the Quantize Tool will adjust them to eighth note positions.

Logic Pro Quantize parameter values — Apple Support

The Quantize parameter is non-destructive. It adjusts the playback positions of notes in MIDI regions when Logic Pro is in playback or record mode. The original positions are kept in the regions, so you can go back to the original timing.

  Separate MIDI Region by Note Pitch

Separates the MIDI region into multiple regions, each with only one note pitch. Each note pitch gets a separate track. Remarkably handy for drum parts.

Demix MIDI regions in the Logic Pro Tracks area — Apple Support

This feature is especially useful for separating drum parts that have been recorded into Logic Pro from a drum machine where all notes are on the same MIDI channel. Each note region can then be assigned to another channel strip, or perhaps some can be deleted, to thin out the original drum pattern.

  Show/Hide Arrangement Track    ⇧⌘A

Show or hide the Arrangement track. The ‘Show/Hide Arrangement Track Only’ command remove all Global tracks from the display, and toggle the visibility of the Arrangement track.

Edit arrangement markers in Logic Pro — Apple Support

After you add arrangement markers to the arrangement track, you can use them to rearrange your project. You can select arrangement markers, move and copy them, replace them, and delete them from the arrangement track.

  Reverse On/Off ⌃⇧R

Toggles the Reverse parameter of an audio region on or off. When it is On the audio is played in reverse.
