Excellent keyboard. I'm very much a beginner piano player. I currently have a Yamaha P115 piano but needed 61 key keyboard for a small space. The contenders were a Roland Go or a Yamaha NP12, until I stumbled on to Casio's latest releases.
So glad I did. It has some lovely tones, especially the stage piano. The keys, though unweighted and slightly smaller than a piano are quiet nice to play on. The touch response works very well.
After a quick perusal of the manual, I found the controls very intuitive.
The six track recorder is excellent. I was attempting compositions the first evening.
The speakers are good, not great. A good pair of headphones (like the excellent Superlux Hd 681's) work wonderfully.
This keyboard has two great features. It makes you sound better than you are and it's great fun. I'm smitten.
