Hi Starkeeper,
just wondering if you're still interested in Soundfonts.
Vquestor put me onto these ( I'm really grateful he found them) http://bennetng.kc-studio.com/AnotherGS/AnotherXG.html

I've just been doing some sound comparisons between it and my xg clavinova.
They don't stack up too badly.
By the way, they're free.

best wishes
Rikki
