I just wanted to say ONE important last thing: if you want to place down the Variphrase technology, please do not do this untill you have heard a DEMO-PLAYER demonstrate this!! If you play yourself the first time(s) it is NOTHING compared to a pro that knows how to use this!
I heard the song from Bob Marley "Could you be loved" with and without Variphrase and I must say: NO keyboard comes even close when the lady actually sings COULD YOU BE LOVED!
So it CAN be uses, you just need to know how properly, in which songs and you need a woman (in this case) to sample it.
So dont prejudge it !!!!
