Yes, it was buried in a thread long ago, but now I've finally got it up on the site:
You can download it here: http://www.sampletekk.com/tboresource.php
You can get 2 octave demos for the Black Grand here: http://www.sampletekk.com/bgresource.php and White Grand here: http://www.sampletekk.com/wgresource.php

I probably shouldn't say this, but I've actually got a lot of mails from people who actually just stretch the notes to cover the missing octaves and use these demos as full pianos.....
I suppose it's very flattering that people are using our demos as full products!
