Hi Peter,
I do not have the EXB4, but a while back Alex Green sent me an MP3 using the Soprano Voice. Here is his
Full Version of Ava Maria (3MB)
And here is a
Short Demo Version of Ave Maria (270kb)
IMO, The Voices on the KN-7000 are unmatched by any keyboard. The EXP4 is even better. It's just incredible.
I hope I helped you all out. Anyway, it's not a bad deal to reminisce with Alex and the good 'ol KN-7000 days
