Well, one company has been working on this using recordings of piano
playing. While I may have already mentioned this on the list but there is
a company Zenph that takes older recordings, and will attempt to isolate
the fundamental freqencies, with amplitudes and create a digital file and
then play it back on a disklavier. They sent me some some of their promo
materials. It included a Cortot performance of some Chopin. What I found
interesting was that while indeed they did a fine job, the technology
seemed to amplify the limitations of the technology used for the original
recording...for example, some of the treble notes came across as
significantly louder than when I made some eq adjustments to the original.

Potentially powerful use of technology, but tricky.
