I purchased the PX-320 in January, 2009 in Japan thinking to revive my skills having grown up playing on an upright. I was overwhelmed by the sound, feel and overall functionality of the keyboard. The onboard speakers weren’t great unless you crank up the volume but with the earphones – AMAZING!! The keyboard also included everything else I needed – pc connectivity for MIDI, learning mode, recording, accompaniment – you name it, it had it. It’s also portable with a very low footprint which was just perfect for a small apartment.

Once ordered, I probably got one of the first batch manufactured. With that in mind, I made sure to spend a little extra and get an extended warranty which was probably one of my better decisions.

Keyboard arrived, I unpacked and assembled all and started going to work. My prime goal was to exercise my fingers so I started with the Hanon exercises pretty much everyday. If you know these exercises then you’ll know that the keyboard will get used extensively!

After approximately four or five months of Hanon, the keys started giving a rattling sound like something was loose inside. With more playing, more keys got worse. The problem seemed to occur principally on E & F, followed by C keys. I called Casio and got a service engineer whom proceeded to `grease up’ the inside of the keys which reduced the problem for a short time until I started with Hanon again after which the keys went really bad. Another call and they replaced the mechanical keys component.

All was fine until E & F keys started failing again. Same problem, same symptoms and same gradual degeneration as the piano gets played more which is really sad given that Casio have worked hard on developing the sound system and the mechanical feel and they advertise this as a selling point.

Anyway, to cut a long story short I called Casio again and they now refuse – yes, REFUSE – to service the item stating that the same problem will happen again so why fix it!?! They also refuse to refund my money. It’s ok. I still have a five year guarantee. They’re under contract!

My point to this whole posting is to notify you, a possible purchaser, that I believe the manufacturing process for the mechanical parts in this keyboard is flawed and they do not test the keyboards rigorously under a strict quality control program. Otherwise, they would certainly have found the issue and fixed it. This problem will not surface under normal non-repetitive leisure playing 10 minutes a day – at least until the guarantee has well expired. The key module may also be used in other Privia models including the 700 series. Buyer beware!

Purchased this item for my 20 year old son. Has been playing it for 3 weeks. The sound is good and he says it is better with headphones. He uses many of the extensive number of features. This piano is full size and heavy so it needs a sturdy stand.

Very pleased.

For those thinking about buying this keyboard-

There is already an update to this product. The Casio PX-330 has more sounds, better action, more realistic samples, a lettered display instead of just numbers, and is the same price.

From my experience the PX-330 is an excellent keyboard.

I bought this keyboard about 2 months ago and I have really enjoyed it so far. The piano tones sound great and about a thrid of the other tones are very usable. The others sound decent too, I just have no use for them. The action seemed a little heavy (slower) at first but I have gotten use to it now and it doesn’t affect my playing at all. As some other reviewers mentioned, it is kind of a pain to scroll through the tones becasue you have to hold a button on the right side of the keyboard and hit ‘yes’ or ‘no’ to scroll up or down through the tones on the left side. But as they also said, the memory registers allows you to store the tones you like for very simple access. I spent a couple of days listening to each sound and storing them as I like and now I get get any sound I need with about 3 button presses. Overall I think this is a great product for this price, the only issues that I have run into so far is this: First, some of the lower bass notes become muddled if you play in the lowest 2 octives. Sometimes it’s not so bad but it can be depending on the song. Second, the included pedal is ok but not great. But this can easily be solved by just buying a better pedal. Both of these issues are probably related to the price range but the pros outway the cons by far regarding this. I have not been playing piano very long but I have had people play this keyboard that have been playing for years and they had no complaints. I would definitely suggest this product to anyone intereted in a keyboard in the $700 range, although I think Casio just released PX-330 which has a pitch bend wheel, more tones, and a different sound source – none of which really mattered to me. But maybe that just means that you can get this great keyboard even cheaper.

I bought a Casio PX-110 as a Christmas present for my 15 year old grandson who was learing to play the piano. After 10 months of careful use a single key stopped functioning correctly. I had the credit card receipt for the purchase, but not the original sales receipt. I sent Casio the paperwork I had plus a notarized letter on the circumstances of the purchase, per their request. Casio says they didn’t receive the documents and would not repair it under warranty. They wanted to charge me $257.00 to repair one key, which I declined to do, fearing another key would break, and bought a Yamaha keyboard instead. I feel that it is a serious quality problem when a keyboard breaks in less than a year, and a design problem when it costs over $250 to reair a simple problem.

I have played the Casio PX-320 for a couple weeks and am a beginner/intermediate piano player. The PX-320 keys have texture and shape and pressure and volume range and return speed that invites making music. The PX-320 is scaled (graded) so that treble notes are easier and quicker versus bass notes are harder and slower. The keys are weighted and have a simulated hammer action. For my taste the keyboard is a joy to play and is close to an acoustic piano.

I think the Yamaha YPG-635 and Yamaha P85 have at least as good touch and piano sound. I liked the Yamaha YPG-635 display and controls and features and sounds. The YPG-635 is too wide to lay flat in my car while the PX-320 lays on my back seat or back floorboard. The PX-320 base is flat and as large as the top, unlike the P85 that has a base smaller than the top. The P85 has 10 voices. The PX-320 weighs 26 lbs (12kg).

The PX-320 has 11 one-touch sounds like grand piano, electric piano, organ, strings and synth-voice. The PX-320 has 60 wide ranging Casio voices. The PX-320 has 128 General MIDI (GM) voices and 2 Drum Sets. I am pleased with the variety and quality of the voices. I like the large 3-character display and miss a numeric keypad and graphic display. The speakers are fine for a bedroom or living room. If the recessed screws underneath the back are loose the speakers can cause plenty of subtle or annoying noise.

I like the Casio PX-320 price, car fit, finger action, voices, 5 song recording or playback with as little as 2 key pushes, and usable speakers. I look forward to exploring 2-track recording, quick registration, 70 play-along rhythms, and flash memory slot. The Casio PX-320 is enjoyable to play and delightful to hear and easy to learn.

This keyboard sounds like a real piano and looks great in the room. no need to box it up and crate it away when done practicing. it can stay out all the time ready for practice at a moments notice. just turn it on and play.

I have been “playing” a piano for 30 years, but I am not any sort of accomplished musician. I am mostly self-taught. But I know what a real piano feels like and how it sounds. My main piano is a 10 year old upright with a very satisfactory action and bright sound. The Casio comes very close to feeling the same and sounds even better. I have no complaints. I love it. I especially like the touch of the keyboard, with lighter weighting on the high notes and heavier weighting on the low notes. I find myself playing the Casio more often than the upright, simply because I enjoy it more.

The other reviews explain all the voices and features rather well, so I cannot improve upon that.

I also purchased the Drive K80 amplifier for playing this Casio with a couple of friends. Drive K80 Keyboard Amplifier That works very well for this purpose.

For this price, it is a great purchase.

This item shipped fast and arrived in excellent condition. The assembly was easy and quick.

I am not 100% happy with the sound, but it is good enough for a few years because I am just leaning how to play piano. However, it feels and plays like an accoustical piano. The pedals work well and unlike an accoustical piano I can record my playing.

For the price it is worth the purchase and will be a good piano for me to learn on.

I would give this 3 – 4 stars.

I bought this item to fit into my very small New York apartment – (I have a grand piano in a country house). Once I got used to it, I enjoyed it – it has a very good tone and touch (weighted keys), but there is a slight problem in that there is an underlying ‘clacking’ sound to the keys, which I find a little annoying. Also, the pedal is somewhat disappointing. All the same, I like it and am very pleased to have it.
