New Casio PX-150, PX-350, PX-750 and PX-850 Privia Digital Pianos

Share

Casio recently announced four new digital pianos in the popular Privia line: the PX-150, PX-350, PX-750 and PX-850. All of these instruments provide a realistic sounding and authentic feeling piano-playing experience, complete with built-in speakers and multiple instrument sounds. The new models feature Casio’s proprietary AiR (Acoustic and intelligent Resonator) sound engine, which utilizes more than three times as much memory as the previous generation of these keyboards. This translates into providing more detailed and nuanced sound quality.

When you use a sustain pedal with the new Privia keyboards, the damper resonance and hammer response is simulated for added realism. The keys have been redesigned as well. The 88 key scaled hammer-action keyboards have a simulated Ebony-and-Ivory feel, and tri-sensors help to recreate the speed and response of real piano keys. All of the new Privia models feature class compliant MIDI connectivity through their USB ports. This means that you can plug them directly into a Mac or PC computer and use them as a keyboard controller for software instruments.

Here’s a closer look at the separate models and the differences between them:

PX-150

The new Casio PX-150 features 18 instrument sounds, 60 built-in songs and the ability to record one song with two separate tracks. The PX-150 doesn’t come with a stand, but it does include the SP-3 sustain pedal. You can add a full complement of piano pedals to the PX-150 with the separately available Casio SP-33 pedal, which features damper, soft and sostenuto pedals. There is a dedicated port for the SP-33 on the bottom of the unit. The CS-67 stand is also available separately for the PX-150. The two accessories can be purchased together in the PAC 2BK bundle. The PX-150 is also available in white. The CS-67 stand and SP-33 pedal bundle is also available in matching white.

PX-350

The new PX-350 is a good option if you prefer digital pianos that have more instrument sounds and auto-accompaniment attributes. It features 250 instrument tones and 180 built-in rhythm patterns. Like the PX-150, you can add a full set of piano pedals to the PX-350 with the separately available Casio SP-33 pedal, which features damper, soft and sostenuto pedals. There is a dedicated port for the SP-33 on the bottom of the unit. The CS-67 stand is also available separately for the PX-150. The two accessories can be purchased together in the PAC 2BK bundle. The PX-350 is also available in white. The CS-67 stand and SP-33 pedal bundle is also available in matching white.

PX-750

If the features of the PX-150 sounded appealing, but you were looking for a keyboard with an included stand that had a more traditional piano presence, the PX-750 is the way to go. Its specs nearly match the PX-150 note for note, with the exception of the damper, soft and sostenuto pedals, which are built into the PX-750. The incorporated stand is complete with a sliding keyboard cover for a true acoustic piano vibe.

PX-850

While all of the new Privia pianos feature built-in amplified speakers, the new PX-850 turns it up a notch by offering the same large drivers as the PX-750, but with additional 2” tweeters, and more than twice as much power. Likewise, the maximum polyphony on the PX-850 is 256 notes, as opposed to the 128 note maximum polyphony on the rest of the new Privia keyboards. The additional polyphony makes for richer tones, especially when you’re taking advantage of the keyboard’s layering ability.

With regard to the casio px-150.I would like to purchase one ,however can i connect this item to a pa system.I don't see any 1/4 inch l-r jacks to do this,or is there another way..thanks

Hello Martin -

The black Casio PX-150 Privia 88-Key Digital Piano has two TRS headphone outputs, one of which could be used to send a signal to a pair of powered monitors.

The 350 has line-in. I love the idea of hearing synthesized piano from computer via keyboard speakers. The 850, though, does not have line-in. With better speakers, why not? Or can that be accomplished through some other means ...

Hello Eric -

Casio made the decision not to include a line input on their flagship full sized Privia.  Unfortunately there is no work around.

Yamaha? This is a reflection of the poor quality of your comments. It's Casio.

My answer is correct but needs to read “CASIO” instead of Yamaha. We have since made the correction.

I just bought a 150. I'm in sort of a pickle because when I press the sustain pedal (either the included one or my universal) I get noise. Sort of sounds like the strings being un-dampered but at this point Casio is saying its not supposed to do that. Have you experienced pedal/damper noise? At full volume, without pressing any keys, step on the pedal. Do you hear anything? It comes from the speakers or the headphones NOT the actual pedal btw. Thanks.

Hi Bill -

It sounds like there is a short or open ground in the keyboard somewhere. You may return the keyboard to us within 30 days of purchase for exchange under the terms of our return policy.  If it has been longer than 30 days you are covered under Casio's 1-year limited parts and labor warranty.

Hi, Bill, my PX150 has the same problem, please let me know if you found any solution. Thanks.

I bought this digital piano today. I have hearing the same noise. I am interested to know if you guys found any solution to fix this ? Thanks.

Hi BK -

It sounds like there is a short or open ground in the keyboard somewhere. Or there may be dust or pet hair in the pedal's contacts.   We are not aware of a broadly ranging problem with these keyboards. You may return the keyboard to us within 30 days of purchase for exchange under the terms of our return policy.  If it has been longer than 30 days you are covered under Casio's 1-year limited parts and labor warranty.

I have had my PX-850 for just about a month now and there seems to be something wrong with the damper pedal, namely it isn't dampening as much as it used to!

I haven't changed the settings recently, I changed them to my favourites at the start and they've stayed that way, maybe it's just me but the songs just don't sound right because there is hardly any sustain!

I have not dropped or damaged the piano in any way, I set it up in my room and it's moved once the whole time, what should I do?

Can anyone link me a video of them playing scales on their PX-850 with and without the damper pedal?

Hi Hayley -

Since the damper pedal is a simple switch, your issue may be one of dust and/or pet hair in the contacts. Since the unit is under CASIO warranty, you may wish to contact them for service or technical support:

I am planning to buy PX-150 and was just wondering if the USB cable comes with the piano because it doesnt say anywhere whats included in a package.

Thank you in advance for the answer.

Hi Vova -

Casio does not supply a USB cable with this keyboard.  You will need a USB "A" to USB "B" type cable.

The Pearstone USB 2.0 Type A Male to Type B Male Cable is a Universal Serial Bus (USB) cable that supports transfer rates up to 480 Mbps. This cable is designed to connect to a PC, Mac, or any USB device. It features a USB type A at one end and type B at the other end and offers high speed transmission to maximize conductivity and minimize data loss. It is fully compliant with USB 2.0 specifications.

On two differnet PX-130 pianos I have had a problem with a particular key (it was differnet on each piano) sounding as if I were hitting it full velocity (the shrill sound of hitting the key really hard) when I was not hitting the key full blast.

It was/is intermittent. The first time they ended up saying it was a problem with the rubber contacts or something, but they ended up giving me a new piano (it was a heelish experience over months bringing it back and forth to Brooklyn and then shipping to New Jersey before the sent me a new keyboard). Now I am having a problem (different key) with the replacement piano they eventuall sent me.

Anyone else have this problem.

I just started having the same problem with my PX-850 Digital Piano. It is the "D" key just after middle "C". I just sent support an email. I have had the digital piano since the end of November 2013, but I didn't put it together and start using it until about 4 weeks ago. It was fine at first, but suddenly this problem appeared today. I sure hope that I don't have to ship this thing. The weight and cost is enormous.

I'll update....

Yes I replaced mine for one key making a louder mechanical noise, like knocking and the second unit was worse all the units they had on display ps5, px350 and 150 had that in different keys I'm keeping the one with only one key but very disappointed.

Hi I've had a Casio PX 150 for two months now. I absolutely love it but now one of the notes don't work properly. It cuts off really quickly even if I am still playing the note. I haven't moved the piano since it's been here or anything. I have no idea why it's started doing that. Do you have any suggestions? 

Hi Cathleen -

I am sorry to hear that you are having issues with this digital piano.  It may just be a matter of dust or pet hair. Since the unit is under CASIO warranty, you may wish to contact them for service.
