Nothing less than 1:1

Welcome to a new dimension of recording and reproducing playing, practice sessions or concerts on a grand piano.

CEUS-Musical emotions and virtuosity are authentically reproducible

Invite and Impress Pianists at Home

For the first time, a pianist can experience himself “live” from the listener’s standpoint thanks to the CEUS reproducing system. Artists can record anywhere, without studio stress, without taking into consideration the entire musical span of a work. For the first time, direct live recordings are possible from a concert hall without disturbing background noise. Compositions and improvisations can be recorded and documented.

Unmatched Precision

A scientific study by the Vienna University of Technology showed that differences in sensation between “mechanical” and “human” interpretations lie primarily in the precision of reproducing the moment the key is struck.

Bösendorfer therefore set the goal of attaining unprecedented recording and playback quality, to be able to reproduce authentically the entire depth of feeling of interpretations.

CEUS features the ability to record every key movement, including the resultant dynamics, and reproduce it 1:1. It is thereby possible for musical works played once on CEUS to be played back in their original quality. The Bösendorfer CEUS is an ideal instrument for practicing, as well as for preserving important musical events for posterity.

When may we demonstrate the CEUS to you?

Technical Data

Precision of reproducing the moment the key is struck:
Under 2 milliseconds!
Hammer movement before key is struck:
The time for the 3.7 mm distance to the string is measured directly on the hammer head at a precision of 0.001 milliseconds.
Key motion after key is struck:
8 mm are sampled in 250 steps per millisecond.
Pedal movements:
The entire path is sampled in 250 steps per millisecond. Dynamic levels:
Continuous (infinite)!

CEUS Library

It consists of 1500 historical recordings (classical music, dinner music, opera etc.) of famous pianists like Vladimir Horowitz, Artur Rubinstein, Sergei Rachmaninoff (to name but a few) that you can listen to on your CEUS.
