I have the VP770 and love it. In addition to what you see in the videos, I also use it as a controller for my BK7m. On the VP770 though, you have to have the playing skills to get out of it what you heard in the videos. You don't, however, have to be a great singer, as it does a fantastic job of pitch correction. It also has a few nice internal voices as well as AUDIOKEY (which is fantastic).
