very much appreciated Chris !!!
I just downloaded a few zip files from this page
https://psrtutorial.com/sty/yamaha/psr-s970.htmlwhich are the Onacimus' Styles For The PSR-S970/975
that are from 18 April 2020 and were converted from
Genos, the SX900 and CVP-809 (it is right below
the internal style lists of the S970/S770).
There is also an excel there which has the comment of
'GENOS V.2 Superior styles' for some of the styles,
so maybe these include the styles you mentioned.
I would still be very interested in the styles you mentioned,
so would be grateful if you could send me a link to those
and maybe I'm a pig :-) asking if you have any of the other
styles from any premium pack, like the vintage keys one.
Thanks,
Ty
