I'm very interested in this topic .
On the KN7000 there is a super "female soprano soloist " voice it comes from one of the 4 expansion boards I had installed .
I would love to know how to carry out this operation and then load into my GEM XP expander !! (which is much smaller for gigs)
I did a gig for a friends wedding in Italy a few years ago and I brought the house down !! so to speak with my arrangement of "Nessun Dorma" using the almost Human sounding female voice!! and half way through the song adding a driving House beat rhythm !! from a stunned surprised audience every one suddenly got up to dance !!! I'll never forget that moment !!
It also goes done well in the Uk and the USA

So any tips on how to carry out the sampling would be most appreciated !!

I should add that I'm a midi accordionist rather than a keyboard player
