I have a digitech Talker. I run it through my XP-80 using some sort of saw wave. I found a wave on my XP anyway that when I run it through the talker I can play notes in the upper register and sound very convincingly like a woman. Doesn't work for talking though, as it doesn't follow the actual pitch of your voice. If follows the volumes well though, and is astoundingly intelligible. My sister was stunned! I can sing like an angel, or like a chorus of angels.
