Casio PX-S1100RD

This keyboard has some really great piano, electric piano and string pad sounds. When it is connected to the Chordana app via bluetooth, you can easily switch sounds and adjust many parameters, such as key responsiveness, damper pedal sustain and tone quality. Making these changes directly on the keyboard (ie without the app) probably wouldn't be as intuitive.

The keyboard feels solidly built, but is compact and comparatively light for a weighted 88-key keyboard. The key-action felt very slightly lighter than an acoustic piano to me, but it is still enjoyable to play. The key-action is graduated, with the lower keys being a little heavier than upper ones, just as in a real acoustic piano. The keys are obviously plastic, but they have a comfortable 'faux ivory' textured matt finish to them.

I opted for the red colour and it's a rich deep red, similar to that produced by another well-known digital piano manufacturer!
