I carefully read the manual when these first came out. Medeli does not have Yamaha's "AI Fingered" recognition mode, which is the best, the most flexible and most logical, out of all Yamaha chord recognition modes. To me personally, that alone would justify spending the extra money for a PSR-SX900 (or even a used PSR-S970.)

In fact, I don't remember seeing ANYTHING the AKX10 could do in terms of features, or do better than the higher-end Yamahas. I got the impression that they licensed the Yamaha operating system minus some of the most desirable features, and repackaged it in a different case for less money. That strategy never made Radio Shack a major player in the home keyboard market. Sorry to be a bit negative, but what am I missing? What's the big draw here?
