This keyboard offers so much I haven't gotten to try everything, yet. I have not used the recorder or USB connection. I like the key action a lot. Also, I went through the sound bank and a majority of the sounds are quality, and I may never get around to using all the sounds in the memory. I did record with this keyboard onto analog tape, and the grand piano setting sounds amazingly warm. I have not tried inputting a recording into a computer for a comparison. From reading other reviews, I was concerned about the quality of sound of the speakers, but they sound just fine for practice. For me, this was a huge upgrade from a (don't laugh) Yamaha PSR-260 (used for ideas and practice, not so much for recording) bought years ago.
