Voice-extension for Tyros (4)

[Axel B]

I downloaded a few voices  with the file-extension .tvn that claim to be for Tyros but they won`t load when trying to use them. I also learned that there are several types of voice-extensions that Tyros 4 recognizes,(.wav, .aif. .smw, .vce ) but not this one. Is there a way to convert voices just like styles?

TVN files were used on Tyros 2.They need to be converted to UVN using the convert programme avaliable from the Yamaha site
