Intro to editing regions and cells in Logic Pro for iPad

The main area in Logic Pro for iPad for editing regions is the Tracks area; for editing cells, it’s the Live Loops grid. Most of those tasks are for arranging regions and cells in your project. In the Editors area, which you show or hide by tapping the Editors button in the view control bar, you edit the content of a region and cell. In the inspector, you can view and edit the parameters of elements you select in the Tracks area, Live Loops grid, or Editors area.

Editors area

The Editors area in Logic Pro can display any of the five editors, depending on the type of region, cell, or track you select. For example, selecting an audio region displays the Audio Editor, and selecting a Session Player region displays the Session Player Editor. Each editor has a different interface and provides editing tasks specific to the cell or region type.

Audio Editor: Shows the track lane of an audio track with all the audio regions on that track. See Overview of the Audio Editor.
Piano Roll Editor: Shows the track lane of a software instrument track with all the MIDI regions on that track, where you edit the MIDI notes inside the MIDI regions. See Overview of the Piano Roll Editor.
Session Player Editor: Shows controls and settings of the currently selected Session Player region. If no region is selected, it shows the button Create Region at Playhead to create a new Session Player region at the playhead position on that track. See The Session Player Editor.
Step Sequencer: Shows the Step Sequencer pattern of the currently selected pattern region. If no region is selected, Step Sequencer is empty, and tapping a step creates a new pattern region at the playhead position on that track. See Intro to Step Sequencer.
Cell Editor: Shows the content of the selected cell. Depending on the region type in the cell, it displays one of the four editors. See Work in the Cell Editor.

If no region is selected, the Editors area shows the corresponding editor based on the region type of the selected track. See Create tracks.

Note: In the Track inspector, you can change the Default Region Type parameter of a software instrument track to MIDI, Pattern, or Session Player.

Region automation

The Editors area is the only place to view and edit region automation. See Show region automation.

Open and close the Editors area

Tap the Editors button in the middle of the view control bar.
You can also tap a selected region to open its menu and choose Edit > Show in Editor.

Show an editor in the Editors area

Tap the Editors button in the view control bar to show the Editors area.
Do any of the following:
- In the Tracks area, tap a region to select it to show its corresponding editor.
- In the Live Loops menu bar, tap the Cell Edit button , then tap a cell to select it to show the Cell Editor.
- Tap a track icon to select that track and automatically select all the regions on that track.
  Note: Select Regions on Track Selection has to be turned on in the General settings.

Choose a Catch Playhead option

The ruler in the Audio Editor, Piano Roll Editor, Session Player Editor, and Cell Editor automatically scrolls to always show the playhead. You can turn off that default behavior to concentrate on a section regardless of the playhead position.

Tap the More button on the right side of the Editors area menu bar, tap Catch Playhead, and then choose one of the following options:
- Off: The playhead position does not scroll the working area.
- Automatic: The working area automatically scrolls to always keep the playhead visible.
- Catch Now: This option is only available if the playhead is not visible in the working area. Tap to scroll the working area to the playhead position. This action doesn’t affect the selection of Off or Automatic.

Note: Selecting Off or Automatic in one editor applies that behavior to other editors, including the Session Player Editor, which doesn’t have the Catch Playhead submenu in its More menu.

Tip: Tap the More button on the right side of the Tracks area menu bar, then choose Catch Playhead to set the option independently from the Editors area.
