Oct Range/Inversions button: Switch between two modes: Octave Range or Inversions. The four-position Oct Range/Inversion switch below the buttons is used to determine the octave range or the chord inversion pattern.
Oct Range/Inversion switch: Determine the octave range or the chord inversion pattern. See Logic Pro Arpeggiator MIDI plug-in note order inversions for details on the four switch position behaviors in Inversions mode.
In Octave Range mode:
Position 1: The arpeggio repeats without transposition.
Position 2: The lowest note is transposed by one octave. Once repeated, the arpeggio restarts in the original octave.
Position 3: The first repetition is transposed by one octave, and the second repetition is transposed by two octaves. Once the second repetition is played, the arpeggio restarts in the original octave.
Position 4: The first repetition is transposed by one octave, the second by two octaves, and the third by three octaves. Once the third repetition is played, the arpeggio restarts in the original octave.
In Inversions mode:
Position 1: The arpeggio repeats without inverting the held notes.
Position 2: The arpeggio is inverted once during the first repetition. Once repeated, the arpeggio restarts.
Position 3: The arpeggio is inverted twice, once each during the first and the second repetition. Once the second repetition is played, the arpeggio restarts.
Position 4: The arpeggio is inverted three times, once each during the first, second, and third repetitions. Once the third repetition is played, the arpeggio restarts.
