The sound quality is very good with this digital piano, beats anything in the price range. The sound on the grand piano for example has a different tone when you hit the keys hard to resemble the hard action of a piano, and when you play the keys softer, the sound and tone is soft and sweet. Even though the sound is still a little electronic when played through a $6000 Mackie system, after everything is equalized it sounds great.

It has more features than the average pianist will ever need. The limitation of features comes in when you're trying to get some synthesized effects out of it. Though it is a digital piano, not a synthesizer. I'm overall very pleased with the features that are offered on this digital piano, and it worked out very well in the studio recordings I did with it. The best feature is the realism of the "hammer-action" I believe. It feels exactly like my Yamaha piano that was purchased 10 years ago.

The digital piano is very easy to use if you're not getting into too many complicated things. Many of the different settings the keyboard has involve using a function key and a corresponding key on the digital piano which is not labeled. The book that comes with the digital piano has a very clear listing of what each function is on the digital piano and is very easy to understand. If you know what you want, just get used to which key offers your desired outcome and you're all set. A little more user friendly would've been nice, but you can't complain about the price.

This digital piano has a wonderful feel and is very lightweight with an innovative slim yet sturdy design. The key action is very well engineered and feels great. Though the shell is made of plastic, it all seems very solid from my experience so far. I had a previous casio product made less solid out of plastic as well, and it fell down a flight of stairs. It still works perfectly fine, and I'm assuming the construction of this more expensive digital piano is only of higher quality.

This digital piano is, as I said earlier the best for the price. Casio has really done well with their Privia series rivaling Yamaha in quality in my opinion, but for basically half of the price.

I haven't had to deal with the company regarding the Privia PX-310, but I have dealt with Casio regarding my past keyboard, and they were very helpful, very friendly, and quickly solved my problem.

The digital piano is very aesthetically pleasing as it has smooth lines, is very slim and compact while still offering a full 88-key keyboard with wonderfully weighted keys.

The grand piano voice is very natural as well as many others. Beautiful tones are made by layering voices, particularly the grand piano and electric piano #1. The speakers sound nice though they could be a bit louder. When playing with sennheiser 595 headphones, the sounds are TREMENDOUS. Haven't needed an amp yet, but will try one soon.

Plenty of of options with variations, layers and splits.

Very nicely constructed. Though the shell is plastic, it is strong and probably has a lot to do with the light weight of the piano. I imagine it will be around for quite a while.

From what I have heard, it beats anything under $1,200.

No, it doesn't sound like my grand piano -- but its sound is as good or better than all of the other digital keyboards I test-drove, at several times the price.

I bought the Casio PX310 so I could practice regularly while my "real" piano was in store for a couple of months (sold one house, had to wait to move into the next one). I didn't want any fancy features AT ALL, and was delighted to find that I could just sit down and play without having to learn anything complicated. We've moved now, and there is no way that I will follow through with my original plan to sell it. It fits nicely in a spare room, and I have fallen in love with three things that my grand piano cannot provide: I can practice with headphones -- wonderful when starting work on a new piece, practicing the same tiny sections over and over (which used to result in a miserable spouse), or for playing in the middle of the night; I can record myself (not always wonderful); and it fits neatly into the boot of the car, so the fact that few hotels these days have pianos is no longer a problem.

I am not a natural techie, and the fact that one can just sit down and play was a great boon.

It seems to be quite sturdy, and well finished.

From the research I did before buying, the PX310 represents outstanding value.

It is quite attractive, and certainly has greater aesthetic appeal than I would have asked from a keyboard.

You can tell that it is not an expensive keyboard. you get what you pay for. Nevertheless the sounds are pretty decent if thats not all you are looking for. The only sounds that Im really refering to are the piano sound. It sounds sampled and somtimes fake. the e-pianos sounds fine.

Its really nice for the price. Again, if you are looking for a digital piano, this is very good for the buy. Its competitor is in my opinion the yamaha and the m-audio Prokeys 88.

If you are good with common sense or were born in the last 30 years, you will have no problem with it.

I like the feel of this keyboard, and that is the reason I bought it. I play piano. Piano is my thing. Im moving to Europe for a year as an exchange student and wanted my own piano to not drive ANYONE crazy for playing passages over and over again, etc. I was looking for a slab digital piano for a real decent price, and after SERIOUS looking, I settled for this one. If you like pianos with a harder action, settle with this one. Ive touched the others. Yamaha is significantly softer than this one (which made me not buy it) and the M-audio which I really was going to get, has the black keys indented in the keyboard, so they stick low and yes you can play it much easier that a real piano, but thats not what I want it for. I want a realistic feel. This piano does not feel cheap for the price.

I was able to get the keyboard off a shop.com for 440 plus handling to a grand total of $499. If you think about it if you are shopping for these keyboards, you will get what you pay for. We all want the $ 2500 keyboards, but its just not going to happen. This keyboard will give you what you pay for, and it is better overall than its competitors

Who wants a 599 keyboard lol. Its very nice for the price. its really all I need. However If I wanted to throw away a lot of money, or just found a need to get something better, I obviously would have. its real nice for the price dont get me wrong.

Still put it through a mixer, but the weighted key GM plays beautifully, much better than the CTK-571.

Quick tone switching, Volume dial (not slider!), free damper pedal, all I wish it had was a pitchbend whammybar.

Once you learn the interface, it is the easiest thing to manipulate. However, it's a bit of a pain to learn, although very well thought out and economic.

Would need a hardcase for road use, (don't want a drumset falling on it) but it is well made, no loose parts, reliable sound, well made input/output bits. Treat it like a guitar- don't smash it against things, but it can bump around and fall occasionally without dying.

If they keep up this high quality stuff, Roland & Technic do not stand a chance.

Impossible to find english user manuals online (i bought the display model from the store, and they forgot the manual), but german is close enough, right?

The 310 and 555 have the most appeal to me, as I use them for the GM features not available in the 300 or 700 models. It basically combines all the fun crap from the toy keyboards casio made in the 90's with the quality and clarity of tone available from an actual piano.

At last, a piano I can learn with! This is an awsome instrument to learn on. It was on sale for under $500 and at that price it's a great learning tool. To be honest I didn't think much of Casio as a keyboard maker. I was all Yamaha because of the piano like sound. But after hearing the PX-310 at the store, wow, it was better than my old Yamaha. Also, with this keyboard I won't need piano lessons. Nope, with my laptop and Bank In A Box software and a library of piano videos I will learn an year's worth of lessons - in one month.

Probably the most useful feature, in terms of learning, will be the ability to record and play back. On track 1 I can record the left keys then play back and work out the melody on the right side. Using the video's I can learn stuff I WANT TO LEARN - Not the boring abstract stuff you get from piano teachers. Wow when are they ever going to learn how to teach!

Hmmmm are the option buttons intuitive? Nope, yah have to read the instruction manual and start pushing buttons. Would help if they included examples. If you're buying this piano for your kid, you will have to learn the buttons then show him/her how to work it. BUT! once you understand how the buttons work, it becomes easy. Frankly, the manual sucks. So you write your own manual - after you figure out how to use all the buttons. Yah, you need to make up a manual that makes sense to you!

For the price? AWSOME SOUND AND QUALITY. I WILL USE THIS KEYBOARD FOR MANY YEARS TO COME. This keyboard is my ticket to learning how to play like a pro - and it will be fast! Not the years and years of taking lessons. Yep, within an year I expect to play like freaking Liber-Crochie!!

There is a lot of good stuff out there for low bucks. The PX 310 is one of the best. If you want the high qual stuff then shell out the $2,000. For a beginer, save your wuad until you're up high on the learning curve.

No experiece working with this outfit. But if the manual is anything like what I should expect, then it must suck too!

The PX-310 look really kewl in the corner. I have a lamp over it and a place to put my laptop behind it so I can take lessons from Band In A box and learn all those kewl piano riffs and the blues runs. I can play the videos on my laptop and learn to quickly pickup on hand positions and learn what turns me on. Sure beats taking those stupid lessons from a music store!

The default grand piano is a bit to bright for me. Even after lowering the brilliance, still there was something unnatural about it. No improvment through quality headphones. However the Mellow Piano voice was like a very good natural upright, which I ended up playing most time. Speakers are good, but not as good as yamaha ypg625 which I evaluated in the same time (which also had slightly more natural sound too). The keys have a slighty heavier feel than ypg625. I like this a lot.

Well it has almost all the features of ypg625, but without the lcd screen and the dial wheel and a lot less buttons to get them. so you need the manual to use them initially. I don't need them anyways (auto acco, etc). NO METRONOME!!! - this is serious! especially for practicing with headphones I had to connect my computer to line in with a metronome software

if you just want piano is simple. If you need more you need to read the manual. After a few days though you feel pretty confortable. Still a clumsy old timer, button saving interface, but usable.

Seems well made. Rock solid keys and core. the shell is plastic, but still very nice.

I think it is a very good deal. though ypg625 is close with wood stand, better look, usb, screen, and a more natural sound (but lighter keys).

they responded quickly to my question

it is very elegant. yes, you will like it!

Best sound for the price

I would say 15, I am sure company is going to make banch of money with this product. As a piano teacher I have already recommended it for 2 students.

with the $1500 2ghz dual core laptop with decent external sound card and a software that I already have it beats everything that is avaiable on market today
