Hi Guys,
soundfonts ( many are free) may be an option for getting additional sfx sounds. They can be turned back into a wav file using a soundfont editor ( free).
Could also be a source for additional drum sounds. I've come across tr808 samples etc. Can't comment on the quality.
Can't help with how Tyros 2 sample function works, as I don't own one ( yet??)still deciding.

best wishes
Rikki
