Dr. Werner Goebl authored a follow-up paper under a slightly different title and updated some information.

The first paper titled, \u201cAre computer-controlled pianos a reliable tool in music performance research?\u201d was referenced below by James Fry and was submitted at the Workshop on current research directions in computer music, November 15--17, 2001.

The next paper was submitted to the Journal of the Acoustical Society of America in 2003 and was titled \u201cMeasurement and reproduction accuracy of computer-controlled grand pianos\u201d

http://www.ofai.at/cgi-bin/get-tr?paper=oefai-tr-2003-16.pdf

Both articles used a Disklavier Mark II. At the end of the article Dr. Goebl writes:

The Disklavier measured in this study is certainly not the top

model produced of the Yamaha corporation. Since then, Yamaha

issued the Mark III series and the high end series, called \u2018Pro\u2019

(e.g., the special \u2018Pro2000 Disklavier\u2019). The latter series uses an

extended MIDI format (with a velocity representation using more

than 7 bits), and additional measures like key release velocity to

reproduce the way the pianist released a particular key. It can be

expected that these newer devices perform significantly better than

the tested Mark II grand piano.

I have still yet to locate a comparable study using a Disklavier Pro.

Interestingly enough, Dr. Goebl was referenced in a June 5, 2005 New York Times article titled, \u201cPlay It Again, Vladimir (via Computer)\u201d where he was asked his opinion about the work of Dr. John Q. Walker, the president of Zenph Studios. Zenph Studios take audio recordings of live music and convert that information into a file that can subsequently be played back on a piano as if it was live.
