Michael,
Yes, I started with the voices that I made for PSR3000, but since the Tyros has many more options, I went through each one and fine tuned them for Tyros. And of course there are a couple hundred new voices that are not in the other collection. These will work with PSR1500/3000, but many of them will be lacking because the 1500/3000 don't have the DSP power of the Tyros.

Al,

No, these are not converted. THere's no way to do that with user voices.
