You can view video footage from Ray Chen's Semi-Final performance at the 2009 Queen Elisabeth International Competition here:

Select "Ray CHEN" in the 'Candidate' box, then "16/05/2009" within the 'Date' box, and finally "Semi-Final" in the 'Sessions' box.

Ray Chen used an HP Tablet PC running MusicReader to view the full score (violin and piano, as opposed to just the solo violin part) of the fiendishly difficult contemporary work, "V..." for violin and piano (2008) by Claude Ledoux.

Here are some screenshots from the video, where you can see Ray placing his HP Tablet PC on the music stand, and some terrific closeups of the AirTurn AT-104 with a single Boss FS-5U pedal that Ray used for his page turns.
