The Blüthner Model 1 Grand Piano Add-On from Pianoteq features a modeled version of the famous Blüthner grand piano, an instrument revered by many of the great Classical and Romantic composers. The virtual representation is capable of producing everything from tender pianissimos to thunderous fortissimos, from bright treble notes to powerful bass. The add-on requires Pianoteq version 4.2 or above.
In 1873, Julius Blüthner, the creator of the original piano, invented a stringing system that added a fourth string to each note of the top three octaves. The additional string is not struck by the hammer but instead creates a sympathetic vibration that enhances the tone of the note. This Aliquot system is faithfully reproduced in this software version and in the standard and pro version of Pianoteq, it is possible to modify this specific parameter in order to decrease or increase the effect.
