The demo pa3x using the tc helicon was great, for the vocals, not sure it did anything for the keyboard though. It still sounds much the same as the pa2x or indeed not much better, i mean really, if you love this demo buy a Voice Live 2, its a hell of a lot cheaper, and will work with any midi keyboard. Really I Have a Yammy Tyros4 killer sounds, and Audya killer just about everything, I'm surprised that Korg didn't take the bull by the horns and come up with a killer, as they have with the Kronos. I will wait until PA4x before I will reconsider, hopefully they will get the message
