Casio PX-320

The top three reasons for a slim-line, ultra-light gigging piano:
"Sorry, our concert grand is being used by the dj for his snack buffet."
"We've made some room for your piano right there, on the second bookshelf, between the road atlas & "The Places You'll Go"."
"The bride would like your piano at the top of that stone stairway, next to the condor nest."

What's the holy grail of portable keyboard design? Ask 10 players, get ten answers.
For my own use, as a longtime working pianist/synth player, I have a definite wish-list:
88 fully-weighted keys, good piano, keyboard & assorted sounds, onboard speakers, rhythm machine/arranger patterns, MIDI & USB, stereo outs, slim, easy to carry design, and the weight... please, under 30lbs. total weight.
Sounds impossible to achieve, right?

Chaos theory to the rescue: it must have been an oversight, a design accident.
The holy grail has arrived, at least for myself, and it's made by an unlikely kiddie-keys manufacturer.

In case you haven't seen the specs on the PX-320, here's the details.

The Quick Summary:

The px-320 has the features that pros want in a stage piano: acceptable weighted action, good quality piano voices, stereo outputs, MIDI & USB, data storage, quick access to the basic keyboard sounds that working pianists are most likely to need in a playing situation.
Going further into the use of the many features, arranger-type rhythm functions, will require reading the manual (more than once), and probably printing out reference copies of the sound & rhythm lists.

In summary, the px320 is a good professional stage piano, with all of the required features.

The presence of the onboard speakers, drumbot/arranger, teaching tools, increases the flexibility of the instrument, and make it a breakthough product; the first fully-weighted 88 key piano/arranger keyboard, with built-in speakers, that is easily portable.
Kudos to Casio!

The only modification the Casio requires for professional use is an application of duct tape over the brand names on the audience side of the case, and only if you want to avoid scorn for playing a toy.
We all know that Casio has made kiddie-keyboards for many years.
This one isn't a toy.

Arranger type functions in the 320 are an add-on that grants arranger status to an ultra-light stage piano. The limited 3 digit LED visual interface and lighted LED button feedback make using the drum machine & arranger an adventure.

So far, about a dozen rhythms have emerged as suitable for different styles. My fav has become #22, a jazz-brushes 4/4 pattern, but there are a number of pop, r&b and assorted latin dance styles that also play well.

Haven't experimented too much with the arranger patterns, because I mainly use the drum-bot on arranger-type boards. Canned 1 size-fits-all backing tracks usually seem too limiting, but the drum patterns on the 320 are very welcome (in case the quiet cocktail party turns nasty).
Drum sounds are well-sampled, and the brush kit is a blast for old jazzrs (who... me?).

Two track sequencing onboard, with track 1 as primary track for recording the keyboard & main performance data; arranger patterns, drum machine, effects settings, layers etc.
Track 2 is a stack track, and can be used to add another preset /soundbank tone to the sequence.
This is about as close as you can get to the definition of scratch-pad sequencer. There's no sequence editing possible; you can save the file to the SD card as a Casio format song or SMF.
I haven't plugged in the USB cable & driver, because I'm using it as a gigging board, not a studio controller.

Onboard memory can store 5 songs of up to approx. 10,000 notes for each, and songs can be recalled from both the song memory, or the card, for instant playback. I've used that on several jobs for intermission music, and it works as advertised.

The manual is necessary if you want to do anything more than turn it on & play the presets.
It's 60 pages, relatively brief & well-written. Casio's done a good job of providing clear step-by-step instructions describing the many features that's been packed into the sparse interface of the 320.

Controls:
Minimalist 28 button straight-line layout, conveniently located directly above the keyboard, with most buttons doing double-duty.
Some of the buttons have a built-in LED, and some of them control 1 or 2 LEDs above/below themselves.
Hint: although there's no LCD screen for info, you can look at the LED red-light district & see what is going on at a glance 8-))

The Function button is all important, essentially acting like the Shift button on other boards, accessing the dual uses of the button command set.
To return to the use of the labeled top-line button names, you press the Function button again to turn off the bottom-line functions.
Toggle switch.

Press the "Split" button, and an acoustic bass patch appears on the left side of the split point. Don't want that particular split voice? Any pre-set Tone button that is pressed after pressing the split button will become the split voice. The split voice button is a toggle switch also... press it again to turn off the split.

Changing the split-point is also convenient; hold down the Split button, the key name of the RH BOTTOM key split-point pops up in the LED display, press the piano key where you want the new split to occur. Done.

Layering two voices is like the procedure on many stage pianos - press and hold one voice button while pressing the second voice button, and the voices are layered. Can't triple layer, just two voices, but you can first layer two voices, and then split the keyboard to have three voices working for you. My workhorse P80 won't do that, and it cost almost 2x as much as the PX.

You say that you don't have any midifiles pre-recorded yet, but want to turn on some piano music while you take a break? Hold down the "Music Library" button and then press the "Play/Stop" button; the onboard piano classics song library will crank up your favorite (?) recital pieces! Very nostalgic!

Sound Quality: Piano = 8 Other Pre-sets = 7 Various Soundbank = 7 GM sounds = GM sounds

Main piano sample quality is good. It seems to be a multi-sample, not individually key-sampled.
Both ends of the keyboard sound amazing, like an amplified grand; thunder & ice.
In the middle of the piano, the area where most digitals suffer, the piano sample is not completely convincing because of a slight metallic ringing in the multi-samples mid-range zones. 2 points deducted from the total rating for this flaw, although it may go un-noticed unless you've focused your ears to hear it.
The Yamaha, Korg & Roland primo digitals have better piano samples, but they're also in a much higher price & weight class. Not a fair comparison, but if you're searching for the best piano sound, regardless of the instruments price & portability, you'd probably be happier with the premier keyboards. Or, you could just MIDI your favorite module to the 320.
I don'e have a problem with the 320's piano sample, and really appreciate its "play-ability" across the keyboard; can be very expressive.

Turn the volume level up to max and you'll hear the approximate volume level of an unamplified grand.

The main Tone presets are panned in stereo (play up the keyboard, toward the right, and the sound gradually pans to the right speaker - nice), and the onboard speakers provide some tactile vibration feedback to the keys.

At the default Touch Sensitivity setting of 2 (medium), the PX-320 key action is responsive and even, similar to a medium-heavy piano action, without sponginess or overly sluggish characteristics.
The key-up return speed is not quite as fast as a good grand action, so very rapid repeated notes will wait on the key-up delay.
I haven't noticed any difference in the key weight between the upper & lower octaves, like a graded action. Seems to be the same resistance weight for all the keys.

Key width is standard (yes, I measured it - 6.5" per octave, C to C). Take a tape measure to many synth or arranger keyboards; you'll find out why you glitch (hit in between the keys) on those smaller width keys.

Through the onboard 8W stereo speakers, the output is loud enough for small parties and small rooms. I ran it through a tiny 30W Roland cube monitor, and filled a large party room... loud & clean. Even the drum-bot sounded perky.
Used it on a few gigs in ballrooms, and ran the L/mono out through a larger keyboard amp. At a distance, while playing back an on-the-spot recorded midifile, it sounded like an amplified piano, playing what I had just played. Woohoo!

General MIDI soundset is accessible through Tone button #12 or via MIDI, along with a "Various" bank of 60 special voices.

Pre-set Tones:

Three variations on the primary piano voice. The first one (Modern Grand) sounds the most accurate to me. Piano #2, "Classic", is a darker-sounding grand, while the 3rd piano voice, named "Variation", is a mono version of the piano sample.

The Tone button electric pianos are a welcome addition; Elec. #1 is a rhodes-type sample, and #2 is an FM elecpiano type voice, but with a fuller harmonic spectrum and a bright vibes-like attack; sounds like a dual wave sample.
The tone button #7 60s Electric piano is a fair Whirly imitation.

The #9 jazz organ is your basic Hammond 1-2-3 drawbars & third harmonic perc. Has vibrato in the sample (tradition), no way to shut it off to a straight tone, or turn on a full leslie effect; sounds reasonably authentic.

We've all heard #10, Strings, many times before. Don't expect rosin to come flying out of the speakers, but it's a good String ensemble, and sounds convincing as a pad.

Voice #11 "Synth-Voice" is an Oxygen-Choir type patch, an instant newage pad.

Final sound analysis; stage pianos need a playable, solid piano voice. This board has that. Anything else is a bonus.

Cons:

I swore that I would not complain about the 3 digit LED display, mainly because that's all I have on my work-a-day P80. The interface works fine, once you get accustomed to the LED digits instead of LCD screen data.

OK, 2 gripes.

First complaint concerns Casio's sustain pedal polarity. The other synth makers have either standardized their pedals, or provided, via a software utility page, a polarity switch for the sustain pedal. Casio should do this as well.

Solution: third party switchable-polarity pedals are available. I have one, but it's not as stable as the excellent Roland DP series with the swivel heel rest to keep the pedal in place. Of course, the Roland pedal won't work with any Casio keyboard.

My 2nd complaint concerns any modern arranger/drum machine. Tap-tempo buttons have been in existence for at least 20 years. They should be standard equipment on auto-rhythm modules by now. Keeps the baby-sitting chores on setting/changing tempo at a minimum. I haven't seen any Casios with tap-tempo... maybe on next years lineup?

Wish-list:
An LCD screen display (like the PX-575), switchable sustain pedal polarity, tap-tempo button, data wheel or 10 key pad, MIDI SYSEX send/receive & save to card, pitch-bend & mod wheels... and cupholders, lots of cupholders... oh hell, now I'm wishing for a keyboard that transforms into a minivan after the gig.

Pros:

There are many thoughtful touches throughout the keyboard panel.

A setup memory function allows for setting up the panel the exact way that you want the instrument to power-on. OLE!!!

You can also set a registration filter to omit the accompaniment & rhythm patterns from the registration memory recall, so you can punch up different registration # sound settings only, without the rhythm pattern & tempo abruptly changing to the pre-set registration pattern.
The registration memory (96 total registration memory locations) also stores the effects settings (Brilliance, Reverb, Chorus), splits, layers etc. along with the individual Tone Voices, so you can have separate EQ & Effects for every one of your sound combos.

Easily reset any of the displayed function values to their default with a simultaneous press on both of the No/Yes buttons.

Back panel mounted stereo L-Mono/R outs & ins. This is a big deal at a time when many of the inexpensive keyboards are only sporting a headphone jack for their output.

Basic MIDI functions are supported; changing the MIDI channel, turning "Accomp. & rhythm pattern out", and "Local", on/off, are another job for the Function button along with the MIDI button.

USB connectors to a pc are not a substitute for MIDI plugs. USB synth connections are proprietary interfaces that require a computer & driver software to work. Having MIDI plugs means you can drive any of the zillion MIDI modules that exist.

The PX-320 does MIDI, AND it also has a USB "B" connector for a pc hookup. This is ideal; the PX-320 is CONNECTED.

HC asks: Would you use it on a gig without a backup?

No, I always carry a small backup board & amp. Always.
Things happen. Murphy's Law.

The first unit (brand new, not a re-pack) that I purchased had a sound problem. Mid-range on the piano sounded dull, without the higher frequency resonance that I had heard on the store demo (through the onboard speakers - no outboard signal tricks or different internal EQ settings).
I returned the first one for another copy, and the second one sounded fine, exactly like the store demo that had impressed me.
May have been an isolated problem with the first unit, or maybe Casio made an adjustment during the product run.

Harmony Central Asks: What if it were lost or stolen?

Lost... stolen... from my motorcade?... with the paparazzi everywhere? How could that happen? Have to change security companies, hire new bodyguards...
OK, I'd buy a new one in a minute; probably get a better blanky to cover the stuff while it's in the van.

HC asks: Did you compare it to other products? Which ones? Why did you choose this one?

Compared it to the Yamaha P85 (70, 60), CP33, YPG-625, DGX-520, Roland RD series, Korg SP series, and the Casio PX-575, 555, 310.
All of the other products were either lacking features, such as Line-outs, MIDI plugs, drum-bot, onboard speakers, or were over my arbitrary 30 lb. weight limit.

HC also asks: How long have you been playing? What other gear do you own?

Been playing a loooong time. Have mucho gear, including a vintage Yamaha PF70, from the 80's, that has a fabulous action.
Too heavy to cart to gigs, but it's still a great practice piano.

Conclusion:

Category rating of 10 for this section is one of those situations where the sum total is greater than the individual parts.

The thing I most like about the px320 is its play-ability combined with its portability.
At 26 lbs., it's 10 lbs. lighter than my primo P80.
The Casio definitely wins the "I want the piano up that winding staircase to the balcony, please", contest.
For in-&-out gigs, with only the onboard speakers, the CasioCutie is superior to anything else that is in the same weight class.
And, you can actually play the little board like itsa piano! No sponge cake, please.

I'm looking forward to seeing how it holds up under professional use. Already had the 320 out on 3 gigs, and it performed well.
Slid it into a wheeled road runner slim 88 case, and it's a breeze to cart around.
I don't know how a fall would affect it, but I'm betting that the plastic case is not ready for unprotected travel.
If the PX-320 survives its first year of gigging, I'll probably get another one as a backup. Can't have too many sets of plastic keys!

As I said in the Quick Summary, the PX-320 is a first in its class, a breakthrough instrument, and should be a hit with working pianists looking for a lightweight, inexpensive, weighted-action piano/arranger 88 to sling around the job sites.

Thanks for reading. I hope that this review helps in your research for a digital piano.

I just ordered the CASIO PRIVIA PX-320 over the PRIVIA PX-200 recently. And finally it arrived. after almost a month (30 days of shipping since the PX-320 is not yet available locally within our area and is still on "order-basis").

I've tried playing a couple of notes and chords for the preset sounds/patches to see any improvement and after 2 days of tinkering and playing music with it I'm beginning to appreciate the improved grand piano sound of the PRIVIA digital piano. Although it uses the same AiF sound compression methods as the PX-200, the PX-320 offers in addition to 128-note polyphony, a DUET mode, dual earphone/headphone jacks, a panel control lock and 202 preset tones ( a combination of Variation tone, panel tones and GM tones). The manual is simple and easily understood.

On the outside, it may look rather "simple" or bland due to its "space-saving" slim design. It's noticeable that it lacks a large LCD screen that more expensive digital pianos have (e.g. Clavinova, Roland etc.). But do not let the simplistic/minimalistic exterior design fool you into thinking this keyboard is a dud, because it can hold it's own in terms of a decent sounding grand piano patch/sampled sound and even saxophone sounds and a vintage electric piano sound.

The PX-320, like its predecessor (PX-310), is meant for home studio/stage use which is the reason why it also has a handy registration bank/memory feature for storing various keyboard settings (i.e. pertaining to use of split, layered tones, patch and rhythm settings) that can be useful for quick patch or setting changes while "gigging". The hammer-action feel of the keys are realistic, you can actually hear and feel the hammer action when you press and release a key.

It has a 128-note maximum polyphony. Using some tones/patch, however, the 128 note polyphony maybe limited to 64-note polyphony...and this is true in using "special tones" like MODERN GRAND PIANO, breathy ALTO/TENOR SAX and other panel tones that make extensive use of more complex samples. However, majority of the GM tones and even some panel tones and variation tones, do not limit or diminish the existing 128-note polyphony to 64-note-polyphony. So, nothing to worry about here.

Unlike high-end synths, workstations or high-end digital pianos-with-some MIDI functions, it doesn't have room for expansion boards for increasing the "preset sound tones or instrument patches".

However, it does have adequate jacks for connection to a PA system/ decent pair of loud speakers (L/MONO and R line out), USB to PC port, MIDI IN/OUT and dual headphones and even a LINE-IN.


Some of the variation tones and panel tones make use of their own "effects" (i.e. reverb and chorus). The reverb and chorus effects each have 4-5 levels. As an example, you can manually set the reverb, say, to a "small room", "large hall" effect.

The keys are "touch response" meaning, they're pressure sensitive, the more pressure you apply in pressing the keys...the louder the sound you produce...and the lesser pressure you apply on the keys, the "softer" the sound (this is true in using all sound patches/tones, except the drum set patch).

It can play STANDARD MIDI FILES TYPE O AND 1. It can record into 2 tracks only and records in Casio's proprietary music format BUT the PRIVIA package comes with a program CD which also contains an application that can be used to convert CASIO recorder music data to STANDARD MIDI FILES (i.e. SMF 0).

You can expand the number of built-in tunes for possible practice by using up to 2GB SD CARDS. You can also use the SD-Card feature as a means to make the PRIVIA piano a MIDI-file player.

The sampled Grand Piano patch, breathy ALTO/TENOR saxophone patches (sounds amazingly realistic), flute and even the violin are amazingly expressive and even realistic. The onboard effects are limited to reverb (4-5 types) and chorus (4-5 types/levels). At least, CASIO has "toned down" the brass section from the old "harsh and loud" brass sounds to a more refined (slight softer) brass section sound.

The touch response is great and responsive to the amount of pressure you apply the individual keys. Great for more expressiveness in playing music pieces or arrangements. Sadly, the PRIVIA series and most of CASIO's products do not have keyboard AFTERTOUCH. But I can live without it and in my humble opinion, the music does not really suffer that much without an AFTER TOUCH feature.

The key resistance is medium-heavy...not too soft (like those in synths and portable keyboard/workstations) and not too heavy (like some poorly made/designed upright pianos).

If you're a wise musician, you'd be acquainting yourself first with any of your music gear before even attempting to use it live on-stage or for a gig. In other words, reading the manual is a necessity to familiarize, if not fully master the basic buttons to be pressed to change this sound/beat to that sound/beat.

I can say that it can be dependable or reliable during gigs, but like I've said, familiarizing yourself with the control/panel buttons would help a lot in making your performance in a gig as smooth as possible.

I don't think I"ll have a problem using it as a main piano/digital piano in a gig but only after I've completely familiarized myself with the controls/buttons and practised with it. Or, I can also use it as a back-up. Either way, I think it's dependable.

So far, I haven't experienced any problems with my PRIVIA digital piano. The whole PX-320, although made of plastic external enclosure, appear sturdy enough especially when used with the CS-65P wooden stand that shipped with the unit. The hammer mechanism responsible for the advertised hammer-action of the PRIVIA series feel sturdy enough to endure "double fortissomos" or constant practices.

When I was ordering through CASIOTONE, the sales people have been friendly and accomodating and were patient enough to answer my inquiries regarding the PX-320. But since, I haven't really experienced yet their AFTER-SALES Customer Support, I'm holding out on giving them a perfect or near-perfect score.

If it were stolen, I'd definitely buy it again. It's a true "bang-for-the-buck" digital piano. It's worth the amount I paid for it.

I love the Grand piano, saxophone, steel guitar, some electric piano patches and last but not the least, I particularly love the 128-note polyphony and the SD card storage feature. The PX-320 is truly a better version of the older PX-310 in terms of added features and better piano sound samples.

If ever, there's something I hate in the PRIVIA PX-320, it's the lack of a PITCH BEND WHEEL and a numeric keypad that will make choosing preset tones/patches easier to select.

I compared the CASIO PRIVIA PX-320 with YAMAHA's DGX-620 but the 128-note polyphony, good hammer-action feel and relatively cheaper price won me over to CASIO's PRIVIA.

If ever there's few other things/feature that the PX-320 had, it would have to be a PITCH-BEND WHEEL (very useful for guitar patches), a modest if not slightly bigger LCD screen and a numeric keypad button for easy selection of the GM tones/variation tones...instead of having to press the YES/NO button simultaneously with the GM/VARIATION TONE BUTTON to scroll down through various patch numbers to select the tone you want. Thankfully and mercifully, the registration memory feature of the PX-320 should make recalling sound patches and other settings easier with just a click of a button.


I've been playing the piano since I was eight and I was trained by my piano instructor/teacher first in classical and second in playing by ear and mastering chords as well (although I know child prodigies started playing even younger and the age I started playing pales by comparison). However, I only started playing keyboards in gigs since my junior college days and so it's been roughly 14-15 years. This does not make me an expert or master in making a review or even playing music, but this experience however, has given me a certain degree of discernment or awareness as to what sounds good over another preset tone/patch, what features come in handy in gigs. what gears you need etc. just like the other musicians out there who have been playing in gigs and using music gears for years.

Straight out of the box, this can be used rather easily. There are 11 preset tones readily available, and then 191 extra various tones. The presets for the most part sound great, especially the piano ones. I found some of the electric piano ones to sound a little odd, but that's just me. There are loads of options to explore that definitely take some looking at the manual, but the manual is pretty easy to follow and outlines everything in steps.

The keyboard has 128 polyphony and over 200 tones to choose from. It also features an SD Card slot, MIDI In/Out, USB, a Line In and Line Out, each of which can either be stereo or mono, and jacks for sostenuto and damper pedals. Also came with AC Adapter and damper pedal. The store I bought from also threw in a free stand and dust cover. I got this piano to replicate a piano. I use it for practicing and gigging. The action on it is the reason I got it. Out of all of the keyboards I have played, this feels th best to me. However, different people like different types of action. It is medium-heavy and is rather quick. Trills and tremolos are easy to execute. Single note tremolos are as expected, not being too great, but not being terrible either.

The sounds coming out of this keyboard are beautiful under the right circumstances. Using the on board speakers, it sounds alright. It is nothing special, good for practicing, and alright for gigging. However, if you plug in a good pair of closed back headphones, monitors, or some sort of PA speaker, this sounds beautiful. I have not had the chance yet to play around with every tone, but what I've played so far has sounded good. I've been mostly concentrating on the piano sounds, because that is what I am going to mainly use it for. When played through a decent speaker, from the lows to the highs, it sounds amazing. The bass is deep and rich. The highs have that beautiful music box effect every pianist dreams of. Everything is well balanced as well. No one octave drowns out another.

I haven't had this keyboard too long so I can't really attest to its reliability. It is light for a keyboard but it seems sturdy.

Haven't had to deal with Casio yet.

I have played piano for 10 years now and play mainly jazz and standards. I needed something to practice with and go out to gigs with. This is not something that sounds like a fake cheesy piano. It is rich and beautiful sounding. The action is great and I have no problem going back and forth between this and a real piano. I highly recommend this to someone who is looking for a portable piano.

Bit fiddly to use...there's a lot more buttons than on the earlier PX100/110 models but a lot more functions. Still trying to find my way around it about 3 hours on


Manuals fine

Don't think there are edit facilities but i may be wrong!

128 note polyphony- this is why i got it, along with the new features over and above the older PX-310. The keyboard action is good- i bought this to complement a Roland FP-5 as its half the weight and is more than good enough for practices whilst i'd use the 'FP5 on the actual gigs.
The action is a bit stiffer than the Roland- the keys aren't quite as easy to push down but that just takes some getting used to.
The keys themselves are fine though and feel like they have come from a more expensive instrument.
Tremolos, scales and very fast repeated notes are handled well.

There is a SD recording facility whcih i haven't used yet.

Apparent lack of internal speaker switch- when you plug in amps to the 1/4 inch outputs they don't mute the speakers so you have to put a set of headphones in to mute the speakers which spoils the sound you'd get from an external amp/speaker set. The Roland (above) has a speaker switch which was really handy!

Velocity/aftertouch are handled well. Can't really fault the action, as per above.

Rhythms are pretty good- not as accomplished as my Roland FP-5 but not bad. Not sure i'd gig with them though (as if someone would gig with a rhythm bank on a piano!)

Piano voices are good, though not through the internal speakers. Stick a decent set of 'cans on (i used Sennheiser HD600s) or through a decent amp and speakers and you'll hear that the sounds are scarily similar to Roland sounds. I'd say its fairly similar to Steinway piano voicing. Impressive stuff!
There's other piano voices, an organ (which is a bit crap), 60s Electric piano and all the usual GM2 voices.

Lots of choice. Stick to piano (i'm a piano teacher) and you'll love it provided you don't use the internal speakers!

no problems so far in 3 hours of playing! Seems well screwed together!

its
a) light (physically)
b) excellent sound potential if you have the amp
c) lots of inputs/outputs
d) well screwed together
e) 2 year guarantee
f) sounds better than equivalent Yamaha
