I was able to load the sounds, BUT, NOT the conventional "Yamaha" way, I had to do it Loading them as INDIVIDUAL voices, like you do the regular TVNs sounds, and automatically will assign them into the Premium Section.

I just wish Yamaha Music Software would UPDATE the procedure, because the steps that you suppose to make to install them, DOES NOT WORK.

It took me a day, but I succeeded, and now I am a happy camper again, so, if anyone buys the new sounds, Download them into your PC, Unzip them, then copying the Unzipped files into the USB, then in the Tyros 4, go to VOICE CREATOR, then INDIVIDUAL LOAD, then is done.

One good thing, I did clear a LOT of the TVN sounds I did not use, and only left the ones I really use a lot in my registrations along with the preset and Premium sounds.
