No, it`s not a particularly popular effect. It`s all but useless live unless the PA in the venue is spectacular. And yeah, I suppose I could automate the pan in my DAW when I record, but I wouldn`t complain if along the way we got a panning delay built in. And not a ping-pong, but a true auto pan. Even the almighty Eventide doesn`t have one.
Yep, that would be cool to have the effect outside of the DAW!
