Intro to regions in Logic Pro for iPad
Regions are the building blocks of a project. When you record an instrument, drag a loop to the Tracks area, or add an audio file, a region is created containing the content of the recording, loop, or audio file. Regions appear as rounded rectangles in the Tracks area, with different region types having different default colors.

You can arrange and edit the following types of regions in the Tracks area:
Audio regions (blue) from audio recordings, audio Apple Loops, and imported audio files on audio tracks. Audio regions show an audio waveform representing the audio data.
MIDI regions (green) from software instrument recordings, software instrument Apple Loops, and imported MIDI files on software instrument tracks. MIDI regions contain MIDI note events and other MIDI data such as modulation or pitch bend data.
Session Player regions (yellow) created using the Session Player Editor and Session Player Apple Loops on software instrument tracks. Session Player regions contain performance instructions that you can edit in the Session Player Editor.
Pattern regions (violet) containing Step Sequencer patterns on software instrument tracks. Each step represents either a MIDI note event or automation data.
You can edit regions in the Tracks area in a variety of ways. For example, you can:
Note: When selecting or editing regions on tracks that are members of a Mixer group, the same selection or edits apply to the corresponding range of all tracks in the group.
