Dave, sorry it took me so long to respond to your very thoughtful comment. I appreciate the link to the self-playing instruments video podcast. There are some really good ones in there. I'm especially impressed by the Self Playing Steinway Duo-Art Piano - recorded by Sergei Prokofiev. That one is nearly as faithful to the actual playback as the Yamaha Disklavier, but is limited by the length of the paper that is recorded on. It's an analog equivalent, incredibly accurate in its reproduction. There were earlier ones, too. That whole phenomenon would merit an entire series but I don't know that much about it haha!
