The CEUS Project
Conceived and organised by US Fulbright Scholar Albert Frantz, this recording event took place 2-11 March 2007 at Paul Badura-Skoda's recording studio in Vienna. The aim was to record performances of Peter Phillips' MIDI files of Ampico piano rolls on a 2006 Bösendorfer Imperial grand piano fitted with Bösendorfer's new CEUS (as in Zeus) high-end computerised player system.

Bösendorfer sponsored the event by loaning the piano and having it tuned and voiced each day. Recordings were made in DVD audio format.


The 13 CDs of recordings were issued in 2010 and were made available as downloads through the Naxos Music Library. The recordings are now available through this website.

Some interesting facts
Badura-Skoda pointed out that the Imperial piano used to make these recordings had the same sound qualities as his 1925 Imperial.

• Bösendorfer provides purchasers of a CEUS-equipped instrument with the full set of Phillips MIDI files of Ampico rolls as developed by 2007 (around 1500 files).

• Yamaha now owns Bösendorfer, in a relatively hands-off business arrangement. The Phillips MIDI files are therefore not given to purchasers of Disklaviers.

• The CEUS MIDI player system was developed in Vienna, following a government grant. It replaces the previous arrangement Bösendorfer had with the Stanhke SE system, which is now no longer in production.
