Thanks, TGP. There are some short classical piano pieces that are played so often, by so many students, that it's difficult to hear them with fresh ears anymore. The aim was to try to use timbres to wake up these 'stale' pieces.
On this arrangement, I was trying to think of how to intensify the musical feeling that was already in the work--but not to step further into a modern re-interpretation of reconception of the piece.
Also, I was just twiddling the settings on the Pianoteq, to see what sort of pseudo-pianos might result.
