Why is there a pre-occupation with all-in-one keyboards/arrangers? One size doesn't fit all, which is why mega instruments cost so much: because they sell to so few. The more feature-laden the keyboard, the more that can go wrong and the more work it takes to debug it. Customer spend thousands just to wind up being a beta-tester. I've lost a lot of faith in MI companies over the years - these days I need an instrument I can rely on when I pay for it, not years down the road.
