I'm skeptical because the nuances of jazz and classical are famously hard to analyze. Just tiny inaccuracies in dynamics and timing can have a huge effect on the feel of a passage, and this technology depends upon computer analysis of timing and dynamics.

Still, if it works, that is pretty impressive.

I went to the company's website and downloaded the two sample MP3s and I don't think the machine-played version has the same deft touch as the human version. At about 12-13 seconds into the human version there is just the slightest hint of rubato (taking time from one note and giving it to others) which does not exist in the computer version.

They don't sound alike at all to me. And if I understand this correctly, it only works for piano pieces . . .
