Wow, what a shame that most people you know that use arrangers are missing out on a fabulous tool, when mastered! My trademark sound has been my vocal group emulation and I would really miss it if the technology wasn't there to support it. I don't just turn it on and leave it on ... I finesse it.
I admit that most people I've heard that DO use harmonizers, don't seem to get the most out of them. It's an art form all to itself, and the singer must rethink the approach when using it.

Apples, oranges .... whatever you like, but the only thing holding me back from using this Nord E3 ( which I LOVE ) is the lack of easy to use harmonizer. I'd have to bring 2 or three more pieces, and it just wouldn't be practical. My keyboard need to serve as a vocal processor, monitor, and sound source. Anything less, and I'd have to charge more! For now, the PA800 is invaluable to me.
