Linear Morphing AiF with 16 tones

The Casio AP420 Celviano Digital Piano’s Linear Morphing AiF system is what delivers the Grand Piano tones. You don’t need to know how it produces the 16 tones that deliver the high quality sound to appreciate it.

3-sensor hammer action

As important as sound is to the Piano experience, it’s almost equally important to the Pianist to have the feel of a quality piano, and this is made possible in the Casio AP420 Celviano Digital Piano by the 3-sensor hammer action.

3-sensor hammer action involves a new tri-sensor spring-less 88 note scaled hammer action technology, with weighted keys, which for most consumers is pretty close to what they are looking for.

“Ivory Touch” surface

Along with the action of the keys, the touch of the keys is equally apart of the playing experience. The Casio AP420 Celviano uses matte finished keys which don’t feel like the cheap plastic ones found on most keyboards and digital pianos.

Speaker system

You can have great package of sound reproduction, key action, and even overall look but if the sound is crappy you have nothing.

The Casio AP420 Celviano utilizes a dual 20 watt speaker system that delivers a full and deep sound which is free of any tinny sounds normally associated with cheap speakers or poor amplification.

Of course the option headphones is available as well.

Pros and Cons


For what your getting the Casio AP420 Celviano has a great price. It delivers a sound which is as good or better than digital pianos costing twice as much. Although there are some complaining that the downward speakers muffle the sound to a degree, its almost a personal thing, because comparing the sound to other pianos and you quickly surmise this to be the better of the bunch.

If you are even remotely displeased with the sound you have options such as headphones which delivers excellent sound or included jacks to connect your own speakers.

The duet mode is a nice feature especially for students who have a mentor sitting with them. Kind of in the same line is the ability to save your performance which is a great teaching tool even if your the teacher of yourself. A SD Card Slot and USP Port add versatility and convenience to an already good system, allowing you to record, play back you music on any device accepting them.

The construction of the Casio AP420 Celviano is pretty decent, the front legs take it to the level of furniture from that of most keyboard systems. The bench seat has been described as equivalent of a tank, rock solid and is adjustable. The keys feel great, solid brass foot petals. This is a great deal for the money.

Great Price…Great Sound…Great Buy.


No storage in the bench seat. The Sheet Music stand isn’t hinged.

Final Thoughts

Simply put the Casio AP420 Celviano is a great product. While the price might be high compared to a department store piano, it’s really very inexpensive at the grand price range. Its quality equals that of a Yamaha costing twice as much so Casio has come a long ways.

Not only does it sound very close to a fine acoustic piano but it has key action and feel to match. Even the foot pedals are solid. The faux front legs and enclosed back make this closer to a piece of furniture then most keyboards. Even the bench is solid with metal construction to support even larger sized individuals with an adjustable seat to boot.

A highly recommended buy if you’re new to studying the piano over cheaper starters because you’ll want to move to this eventually anyways. Plus the Casio AP420 Celviano is great for small spaces like apartments both in size and headphone quality sound.
