I downloaded the update and was all ready to install it on a friend's Tyros 2, but have stopped! He has been having IDC connection problems, where the keyboard has been very slow to recognize the USB WiFi adapter (or, sometimes, not at all). However, I cannot find this update, or any statement about it, on any of the Yamaha Tyros 2 web sites. I'm concerned about loading something that might be an unofficial beta release, as he uses the Tyros for his work. If my statement is not correct, please post a link showing Yamaha's support for this release. Thanks! - John
