Casio CDP-S100 88-Key Compact Digital Piano

The Casio CDP-S100 is a portable digital piano that takes playing feel seriously.

It features 88 hammer action keys with touch response and velocity sensitivity.

And taking playability a bit further, the keybed is designed to simulate the surfaces of actual ebony and ivory keys.

Interestingly, Casio pulled their punches when it comes to sounds, giving this unit only 10 voices to choose from, most notable of which are variations of acoustic and electric pianos, and two organs.

Another notable feature is the ability to control the settings of the piano via USB through an app.

The Casio CDP-S100 continues to rate highly in the market, thanks mostly to its playing feel, which many describe as being reasonably close to a real acoustic piano. There are also plenty of good remarks regarding its piano voicings, which many describe as inspiring and authentic sounding. Ease of use and setup is also another important edge that it has over other similarly priced digital pianos.


With just 10 voices, this digital piano is far from the usual plethora of sounds that portable keyboards provide. But this can be a good thing, especially if you're honing your piano playing skills, which is precisely what the CDP-S100 is all about.


If you're not into playing with different voicings, and good playing feel is important to you, then this should be high in your list.
