Bill:
I own and operate a T2 loaded with HD and 1 Gig in Ram, I almost 99.98% sure, that what happen it was that how owned previously, deleted the TVNs/sounds from the HD and when you booth on (turn it on), the keyboard looks for those samples/voices/TVNs, and because it does not find them, that is why you get that message.
It happen to me at the beguining, whem I loaded the sound from my USB drive, what should I have done is: copy the TVNs into a folder in my HD, THEN, procedd to independent load to a location on my user voices, that way, the keyboard looks for the Path that made when it was loaded the sound, so, if someone deletes the sounds/TVNs, from the HD, that is what happen.
My advise to you, is to get/buy the sounds of your preference, copy them into the HD, then load them, later, you may use those sound for either your registrations, or even the styles.
One thing you should be aware, depending in how many and how large the size of each voice, this makes the keyboard to take more time to booth on.
If you have any questions, email me
