Casio PX 330 Privia Digital Piano REVIEW


Available on Amazon for 22% off

If you’re looking for an exciting new digital piano from Casio, then have a close look at the new Casio PX-330 Privia digital piano.

A few years ago, as I mentioned in the review of the Casio PX-130, I would have just gone to a Yamaha as they had a good series of digital pianos in the past. But now the Casios are getting more popular and I can see why. Meaning I can hear why.

The sound

When I tried the Casio Privia sounds in the latest series with their all new Grand Piano samples and linear morphing, the sound was very clear, exciting and above all responsive. This responsiveness to touch is not just the touch, it is the sound as well. This is where the realism of playing a piano comes in. When the touch responds and the sound responds, you have the ability to express your playing.

This is where the Privia shines, and is what makes you play more and more on it.  The Yamaha in some models can be quite bland in their sound, but the  Privia has the voicing that changes with how hard you strike the notes and gives you the expression of a real grand with 88 keys. The treble and high trebles in particular are rich, full and ringing like a real grand. The bass is rich and powerful as well and has a richer sound than many Yamahas. The scaled hammer action keyboard is a must for realism and satisfaction in playing as it feels real, which is so important.

The Privia 330 has their Tri-Sensor 88-note scaled hammer action keyboard and Acoustic Resonance DSP which means the samples are taken with pedal down as well as pedal up to capture the overtones that comes from pedal down samples. This is essential for realism when playing and recording. And there’s 128-note polyphony which should be plenty for playing with pedal down.

The Specifications

There are effects available as well including 4 reverb, 4 chorus effects, brilliance effects and acoustic resonance effects.

If you’re interested in recording, there’s a 16-Track Recorder, a Pitchbend Wheel as well as 250 on board sounds to use and 180 rhythms.

There are two 8 watt inbuilt speakers, music stand and AC adapter.

There’s a built-in USB MIDI interface for recording MIDI into your computer if you want to produce music and edit it. And there are 2 headphone jacks for practicing with silence, and a second pair for a friend to listen too.


I always prefer the wooden stand which looks better than an x stand if you[re not playing in gigs, and also supports the pedals properly instead of them able to move unattached. The keyboard looks great and has plenty of buttons to access the various tones. For studio or stage, you can put it on an x stand and it weighs 36.2 pounds.

And pedal? Yes, I would get the standard pedal as well. If you want sostenuto, then get the 3 pedal optional extra SP-30 pedal unit to emulate the pedals of a grand.

The difference between the Casio PX 300 and the Casio PX 110 Privia is that the Casio 330 has much more tones – 250 compared to 16 tones, has a 16 track recorder, 180 rhythms and a pitchbend wheel.

They both look great in black and is uncluttered. That said, there are more buttons on the PX-330 vs the PX-130 as there are more tones and rhythms to access, so there are more buttons to enable this.

Is it s winner? Casio has placed themselves into the market very effectively as they are offering a ton of features and superb sound at a price that is lower (much lower) than what you’d pay with other brands.

I particularly enjoyed the playing experience on them, especially the clarity and brilliance of the treble and high trebles. With headphones or speakers they sound rich and contains the right overtones and a great voicing and makes playing enjoyable and exciting.

If you want all the tones and instruments to use, and to record multiple tracks, and use rhythms then the Casio PX-330 is the one that will suit, otherwise if you mainly want the piano sound, then the PX-130 is the one to get.

    I found your review very informative. Have been reading about the PX-330 from other sites and also came across the Keyboard Mag review which has given it a Key Buy in their review.

    Some other user reviews have mentioned sound/note decaying faster in the PX-330. Wanted to know if you found this while you checked it out.

    When you attach an external amp/speaker, does the onboard speaker get cut off?

    Would appretiate your response.

    Hi Brian,

    I have noticed that there is more decay in sound in all digital pianos compared to a good acoustic piano, even with the pedal effect. It’s not that much more noticeable to me than compared to other digital pianos, but maybe others have found differently.

    The main thing is that if you then suddenly play the same piece on an acoustic, you have to adjust your touch to make the melody sound more prominent again.

    In general, if you use the line out, the speakers should cut off. but check with the piano at the store to make sure!

    I purchased the PX-330 a little more than a year ago and chose it because there was nothing else even close in sound/playability within about $250. I’m bothering to post here because of the above comment concerning the Line Out. The first handful of times I used this keyboard which was at a band rehearsal, I plugged the 1/4″ cable in and all worked as expected. Come time for the gig, I plugged in gave the sound man the cable and–damn, no output to the sound board. But the internal speakers were still on. We ended up putting two SM57s on the speakers of my board. When my vocal mic was added in, I looked like I was in a cage.

    I went back and forth with Casio’s customer service people for over a month to get some clarification on my options and they told me that the speakers are not supposed to mute when the line-out is used. Instead, I should put a dummy 1/8″ plug into the headphone jack to mute the speakers and then use the line-out. Well, I couldn’t find anything to that effect in the users manual. However, when I tried this, it worked. Which is puzzling as the keyboard was working the way I expected it would when I first used it. I went back to the place I purchased it (Guitar Center) and was going to exchange mine for another unit. We pulled it out of the box and, sure enough, the line out did not work unless I put a 1/8″ dummy plug in the headphone jack.

    Did the specifications for this keyboard change? I like this piano a lot but somehow still feel I have a defective unit.

    Only the best,

    Hi Roger, re: Casio PX 330 Privia

    “speakers are not supposed to mute when the line-out is used”

    That is, the headphone jack needing to be occupied for speakers to be muted… I suppose the wiring means that the circuits (for speaker and line out) are not either or, and that the speakers always output unless the headphones are connected (or just a 1/8 inch jack), so that it means that the either/or in the circuit is between the speaker and headphones only.
