Al, you're always welcome. I have only spent about 10 minutes with this beast so I know next to nothing. All I've done so far is listen to the two onboard demos and go through most the piano patches (in single mode). The pianos are, in a word, awesome. There are tons of them, probably enough of them that everyone would find one to suit their fancy, but the instant editing available, makes tweaking a breeze. I haven't even opened the owners manual yet, just the Quick Start Guide. The K4 seems to provide a near perfect amplification system for it. Clean, Phat, Soulful; with good acoustic instrument sounds (great pianos) and outstanding drums and synths. With the easy to use sampler, and many performance features, this should be a real blast for live use (once properly prepped) and a honey in the studio. But....wimps beware, this turkey is heavy. On the other hand, it should put you in a position to be able to hire a roadie in short order .
