def/ins/pat file for Yamaha PSR-K1 (XG voices)

Happy New Year, everyone !


I use a Yamaha PSR-K1 as a 'slave-synth' from my PC, and I want to use its XG voices rather than the basic GM set. I'm using a .pat file which I think is just generic Yamaha XG. This gives me most of the voices (the next 127, I guess, though I haven't counted) but that means there are still about another 80 useful (i.e. real music) voices, and there are some voices which I can't access by direct entry - the sounds are plainly not the ones I'm trying for. So I guess I need a more specifically PSR or ideally PSR-K1 file.

Is this making sense ? And if so, does anyone know where I can find such a file ready-made?
