The P37 (piano-type) and B46 (button-type) digital accordions are modern instruments firmly rooted in a time-honored tradition and culture.

Built from high-quality wood, their keyboards use the same mechanical parts as on an acoustic instrument. Similarly, their bellows needs to be moved and generate the airflow typical of an acoustic accordion in order to produce sound.
These instruments were developed with the most demanding players in mind—conservatory students, professional performers, musicians, and teachers.
Great care was taken to preserve the feel of an acoustic accordion and all those little details that have turned acoustic accordion instruments into coveted classics that appeal to the mind, the hands and the heart.
But make no mistake: the series is quintessentially about technological innovation. These evolved accordions are both special and unique, waiting for you to make them your own and to convey your emotions through your music like never before on an electronic instrument.

The P37 and B46 are perfect for all accordionists, combining tradition, cutting-edge technology, and aesthetics in one instrument.
