Casio AP 450 Celviano Review

OK, I will provide a full review soon, however in the meantime, have a listen to the Casio AP 450 Celviano in action here.

Is Casio giving Yamaha real competition (and also Roland) for a great sounding digital piano.

This is one of the new Casio digital pianos and keyboards for 2012 and 2013!

OK, here it is!

I tried the Casio AP 450 Celviano today.

This new Casio digital piano for 2012 and 2013 really show why Casio is a contender when it comes to the top quality digital pianos for under $2000.

The piano looked really good with its upright piano look about it, instead of just being a keyboard.

And a lid you can lift as well.

It was the sound that captured my attention more.

The real pleasure of this Casio AP 450 Celviano piano, which was more impressive than most digital pianos available for under $2000, is the beautiful experience of playing its notes.

Especially the treble, from, just below middle C to the top note, the sound in this range is rich, full and real.

I could almost imagine that the notes played were from a really good acoustic grand piano, as I felt the overtones were there, plus, the speakers were able to produce these sounds amazingly well.

It is this combination of a well sampled sound source, and quality speakers that makes you almost forget that you are playing a digital piano.

If one of these is out, then you start hearing a synthesized or artificial sound. Not good.

However, the treble and top end of the Casio to my ears, always are the strong suit of the Casios.

The Rolands are great overall, however, when you compare the high notes, the Casios almost win everytime.

The Casio Privia 330 and 130 PX high end notes sound surprisingly good for its price range. And the Casio AP 450 Celviano is where they take it to the next level, with a full body in the sound and the overtones to create the neccessary complexity to make it sound good. Not plastic sounding, but good.

When you hear this, you start listening to the sound, and enjoying the sound, instead of wondering why it sounds plastic.

This is where a good digital can sound actually more pleasing than a low quality acoustic.

On the lower notes, the sound samples sound good, however sounds not as impressive as the upper range, as the speakers seem to be not quite enough to make it sound like a grand.

But then, it is always the lower notes that are difficult to make it sound like a Steinway grand.

You probably need the huge speakers of the Yamaha “Modus” to get close, and even then at over $10000 and very large speakers, you can still tell its not an acoustic.

However, for the amazing price range of under $2000, the sound overall is exciting.

I compared it with the treble of the Privia PX 850 and….

I preferred the treble of the Casio AP-450. The Privia 850 in this range sounded flatter, less convincing and more artificial in sound.

If you have never heard the AP450 then you may not know any different. However, for me, the AP450 is more impressive here.


I would say that the touch is perfectly fine, with 3 sensitivities that you can adjust.

I would suggest a medium response to mimic that of acoustic pianos.

They are simulated ivory keys, so they have a slightly textured feel to the surface which is nice.

4 types of reverb to choose from to suit your style of piece or desired effect.

2 Headphone jacks are available, a must for living in an apartment or with others.

USB to computer connection, and also line outs.

Adjustable-height piano bench and music stand are included.


The technical specs mention the following features:

1. Multi-dimensional Morphing AiR Sound Source

2. Adding string resonance sounds to enhance the sound – when a key is truck, there is resonance from other pressed keys

3. Lossless compression

4. Fast and slow key releases resulting in different resonances

5. Damper resonance – when damper pedal is pressed, there is resonance (in varying degrees) from all 88 keys

6. Includes resonances when damper pedal is lifted

The damper resonance is what made me want to try it out to test it out!

The best way to test this is with a piece of music that uses the damper pedal of course.

The sound that comes out sounds more like that of a piano than many keyboards or digital pianos that just sounds like multiple notes put together.

However, when you have added resonance from other notes, the sound you get here is more complex, like you have the sustain pedal actually pressed down.

It’s not overdone in any way or gimmicky, it is just there to add the realism.

The Casio AP 450 Celviano is a must have for anyone who wants a digital piano, cabinet style piano that has great sound, for under $2000.

Yes, you can go for $5000-$10 000 with the higher end digital pianos such as the larger Yamahas including the Modus.

However, this Casio represents good value for money.

    Thank you for a good review. I will probably buy a digital piano for home use, mostly using headphones, and this seems like a good candidate. However, compared to the Roland FP-7F, what are the pros and cons according to you? Also, what piano would you have chosen (not necessarily any of these two) in a similar price class as these two, i.e. between 1500 and 2500 dollars for the purpose mentioned at the start?

    Hi Andreas,

    Ah, yes, headphones with the digital piano, I do this more often than with the speakers at times!

    I would say my favorite 2 are the Rolands FP7F or 4F, or the Casio AP 450 though the 7F has the better bass notes. The highs and lows of the Rolands are good to my ears, the bass strong and the highs, nice and rich. The middle section is a little less impressive. The Rolands have a good cohesion with good sound production, and the entire keyboard sounds like one good instrument.

    The Casio is good from middle C or slightly below and up, the bass is good too, in quality in a way, though I think its the speakers letting it down a little, as of they can’t faithfully produce the lower frequencies making it easy to tell its a digital… However the upper range is palpable, like an acoustic in many ways…

    I embedded another video, to show this treble range…

    How do you think between Casio AP-450 and Casio PX-850 and which one would you recommend.
    Thank you,

    I noticed something odd about the top lid of my Celviano AP-450 and I would be very interested in hearing the opinion of another owner of this model.

    The wooden top lid of the piano consists of two parts: the fixed plank in the front where the music stand sits and the rear plank with a hinge that can be opened.

    On my piano the fixed plank is sagging in the middle right behind the music stand. It seems as if the weight in the middle is to high and there is no support at all.
    As a result the retractable keyboard cover scratches against the bottom of the fixed plank when opening the cover.

    Can anyone confirm this on his AP-450?
    Best regards,

    Hi Flo,

    Did you follow up on the sagging plank?

    I just got a new AP-450 for my son yesterday and I notice the problem you described. The fixed panel is sagging towards the centre. The lid seem to be quite straight though.

    What do you think of the yamaha ydp162 (almost same price). Which piano do you prefer and had the best sound? The yamaha ydp162 or the Casio Ap450

    Regards Richard
