Physical Modeler


Pianoteq is an award-winning virtual instrument capable of recreating the sound of a wide range of acoustic & electro-acoustic instruments.

What makes Pianoteq superior to other virtual instruments is that the instruments are physically modelled and thus can simulate the playability and complex behaviour of real acoustic instruments. By omitting usage of samples, the file size is just a tiny fraction of that offered by other virtual instruments, perfect for use on any modern laptop.

Steinway & Sons have approved the sound and playability of the Pianoteq virtual instruments Steinway Model D and Steinway Model B, which have gained from the refined physical model. These magnificent virtual grand pianos will appeal to all musicians in search of the most famous piano sound signature.

Vivid: The piano creates the sound in real time while you are playing and takes into account all the complex factors that makes the piano a truly vivid instrument, such as the interaction between strings, the use of pedals, the cabinet resonance and the position of the hammers. It will feel like you have a real piano in front of you... as if you could just lean over and touch the strings!

Versatile: Pianoteq introduces new methods to adjust the piano sound to just the way you like it! Changes that until now could only be made by piano tuners are now possible directly from the interface. Within seconds you can adjust the sound to a particular type of music or playing style. The many choices can be saved as a customized setting which you can share with other Pianoteq users.

Expressive: All the detailed variations of the timbre are there, from the weakest pianissimo to the strongest fortissimo! What you express on your keyboard will also be what you actually hear. The sound of even the weakest pianissimo is absolutely pure without any audible quantization noise.
