Hi Dennis. The Korg Pa3x is definitely not out of the question for me, especially with its powerful somgbook, chord sequencer, and tc helicon vh features. That said, if I decide to buy one, I'm definitely not selling my Tyros 4 either because I really love this board. Man, it sure would be great if UnrealBook could implement the kind of cropping features GoodReader currently supports. If UnrealBook finally supports this, I'll then dedicate UnRealbook for all my iPad music display needs. Aaron Nelson, you listening? Yes, calling up Yam Regs via midi CC would be a nice addition too, but far more important to me, Yamaha needs to link and and call up custom Regs from within MuscFinder to make me very happy.
