Choir pack

[Keyboardister]

I used to play "Adiemus" with the 90's New Age style using the  HuhHahMW voice but on the Genos the modulation wheel was removed and so I can't use the joystick but only my
foot pedal but it just doesnt sound the same. The joystick could do a perfect job if the voice was inverted to be HahHuh instead of HuhHah, is there any way I could invert the voices so the basic voice and the MW voice would replace each other?

Just to clarify, the problem is on the chorus of Adiemus where they choir goes: Huh-Ooh-Huh-OOh-Huh , with the Tyros MW it sounded real and natural and hopefully I could do the same with the Genos joystick.

Thanks!
