Here's a thought. With all the griping about how supped up the Demos for new keyboards have been perhaps Yamaha decided to release a true "out of the box" advertisement.

I don't think this is an advertisement as it isn't polished enough especially with some of the key changes, if anything this would be something that was leaked. I've listened to it quite a few times now and I think it's quite plausible that it's from T5 styles, maybe one from the new selection.
