Use chord progressions in Logic Pro for iPad
Logic Pro includes a set of chord progressions that you can use on the Chord track and on Session Player regions. Chord progressions appear in the Chord Progressions submenu with roman numerals (I, ii, IV, V, and so on) for chords indicating their relation to the key signature, rather than as key-specific chord symbols. When you add a chord progression, it adapts to the key signature at the position where it is added.

When you add a chord progression to a project, it functions as a chord group and can be moved, copied, or looped. You can ungroup the chords in a chord progression to use or to edit them individually.

When you add a Session Player to a project, if no chords exist on the Chord track, a default eight-bar chord progression is added to the Chord track rather than a single chord. Each Session Player style has a different default chord progression.
