A milestone of the Seiler engineering team is the patented Super Magnetic Repetition (SMR) Action, permitting unsurpassed repetition speed on Seiler’s upright pianos. This innovative patented technology, unrivaled worldwide, replaces the spring-action repetition of the traditional upright action with two magnets. This permits repetition even in the lower third of the key travel, thus providing pianists with a new dimension to their interpretations of allegro and prestissimo musical passages.
