Choir voices from PSR S970

[samhodgsonpsr]

Hi,
I have a Yamaha PSR S750 and I feel that the choir voices are somewhat limited. Would anybody have the preset voice files from the PSR S970 that they would be willing to share? Specifically : S.Art! SoftChoirOoh, S.Art! SoftChoirAah, S.Art! BoysChoir MW, S.Art! BoysChoirOhAh, Live! BoysChoirAah and Live! BoysChoirOoh. I would also be grateful for any other choir voices (I have heard that one from the Tyros series will only work with a limited functionality but still would suffice for limited use in the left hand section for example).
Kind regards Sam

They won't work on the S770 because they use wave samples that are in the S970 but not the S770.
