I've gone through a lot of digital pianos over the years and if this one holds up, it will be the one I've been looking for. The action is a bit on the lighter side which I really like but still is meaty enough to dig into. I bought it used and I do hear a bit of key squeaking on a couple of the black keys in the lower register but they play fine. I think this piano sound is really good. It sparkles in the upper registers, has lots of body in the lower end, and is nicely dynamic throughout. Though it has only basic editing, the edits have a profound effect on the sounds. The EQ is significant, the effects section, though not big, is of stellar quality. The EP's bark when slapped and the entire sound set is pretty darn good and unique in character. This is also a very good controller. It looks good too. I'd say it's not light in total weight at 45 lbs but still reasonable. One quirk this unit has is that when first turned on there is some strange behavior with the sustain peddle (the one that comes with the unit plus I've tried others with the same result) along with an odd effect on a few of the sounds but when I turn the keyboard off and back on again it's always fine (I contacted the original owner who moved up to the MP8II and told me to do this and I'm ok with that proceedure if that's all it takes and so far that appears to be the case). That may scare some but I'm way too pleased with this keyboard for that issue to override my opinion of it. I guess I could have it looked into but I'm not going to unless I find that it gets worse. Overall I'm really happy having this keyboard as it is a true piano with some solid additional features and I would certainly look into it again should something happen to it. In closing I will say take a serious look at Kawai... you'll probably be pleasantly surprised. Thanks for reading and happy playing!
