Arturia KeyStep Pro Keyboard with Advanced Sequencer and Arpeggiator - Manual (Page 84)

5.3.1.6. Scales, Chords and the Sequencer
The KeyStep Pro gives you a lot of control over the tonality of your sequence. Once you've
programmed a sequence, you can change its root note and the scale it plays in.
To define a new root note for your sequence, hold down 'Shift' and press the Root key (F in
the upper octave), then press a key in the lower octave of the keyboard. The LED above the
currently active root note will light up.

♪ : You will only hear a pitch change when your sequence is already running in a scale other than
chromatic.
