Tony,
Wrong, Korg sells many more arrangers than Yamaha IF you consider world wide sales. Turkey buys those things like we buy flat screen TV's.

But any how, I still have not seen a demo/prformance that is as good as the one I posted on an 'arranger' with no PRO add on modules, studio engineers etc involved. Using a non singer.

James, the demo you posted is not valid in this scenario..THAT GUY CAN SING.

I am aware of a lot of the things used in the studios...and they are cool...but, can you find us a demo/performance of someone that cannot sing, on the PA3X that is this good??
I hope so, as I would love to hear it. (No external equipment allowed). And, It has to show what the Yamaha video did , the singer is way off pitch (I'm not even that bad!) and the sound must be natural and not digital sounding.

Many of us out here, that are not good singers would like to be able to sing on key for our own enjoyment, family ect. we are not talking PRO's here.
