Hi Gerald

the VocWah is based on our popular fx from the DSP4000, used by Steve Vai in the mid '90s. The fx is based on vowels formants filtering. The words simplify the choice for the user. It's a different fx from talk boxes or real wah. The filter superimposes a formant_like tone to the input source. Obviously, like a wah, the effect should be used without dry signal mixed in.
