Hi Don,
I don't know a great deal about the voices, but I think it's the DNC voices that may be of interest to you . They were added to the PA800/PA2X in the last major upgrade . I still haven't quite worked out how to use them properly. haahaa.
BTW, did you ever get a style for Mustang Sally, I beleive you were asking at one stage if anyone had one.
Good news. I've found some Growl effects on some of the saxes. I just wasn't aware which ones and exactly how to trigger the growl. They are more subtle than the Yamaha, but may be actually more realistic. You don't get them by key pressure, but a combination of initial touch and joystick. Still working on it.
