This digital saxophone is a fusion of two technologies: acoustic and digital. It is a new saxophone with the latest acoustic resonance technology yet gives you the natural sense of expressive musicianship you'd expect from an acoustic saxophone. The mouthpiece, key layout, and variety of preset voices provide realistic feedback for your music to move with you. Further personalize the settings, sound adjustments, fingerings, and other controls of the instrument to your liking with the dedicated smartphone app.
