Here's a link to the file and how it came about: http://www.zenph.com/oscar-peterson-march-2007.html
This is not representative of our best-quality files, since we did not have an absolute reference, that is, an actual audio recording, to work with. So, this is not a re-performance, unlike the awesome Tatum re-performances we played for him. There are spots in Tenderly that still are a little bit "not human" -- for example, the chords strike all the notes simultaneoulsy (that is,in MIDI, they're all at the same tick), which we've learned no human pianist can do. When you look at how real pianists strike piano chords in microscopic enough detail, you see the note strikes are at different times and with different touches -- yes, chords are voiced!
At any rate, we did a good job with what we had. And, since Oscar heard and approved of it last year, we decided to post exactly what he had heard. As we get more resources, we hope to work with Mark Fontana (who we think has the best representation of the original data), and make this whole set of Peterson performances into a high-res, nuanced musical treat.
