I have just bought a PSR3K...the only thing I miss is NO aftertouch. Excellent fast USB loading styles and files. Any style is loaded in plays within the next bar, about the same as the inbuilt styles. I am surprised just how good the internal speakers perform. I normally play any board through my Reflex Transmission Line Studio Monitors, but the 3K does not embarrass it's self through it's own speakers. When connected to my monitors the performance is very live and vibrant. Excellent board for the price. The Tyros may be better, but not at nearly twice the price.
