Stage Piano
Reviews : Keyboard
An 88-note hammer-action stage piano as affordable as this seems far too good to be true. Is there a catch?
The PX3 heads up Casio's Privia digital piano range, which for the most part consists of home and education-oriented models with integrated stands, speakers and pedal units. There are no such accoutrements here, though; the PX3 is a proper, portable stage piano with a feature set that makes it much more suited to stage and studio than domestic use.
I must admit a pang of nostalgia when I discovered I'd
be reviewing the PX3. I spent a large portion of my teenage years
playing Casio keyboards. In the 1980s, Casio synths (like the
almost-classic mini-keyed CZ101) significantly undercut the likes of
Roland, Korg and Yamaha and, on paper at least, seemed more highly
specified in some areas, but didn't always come out on top for sheer
sound quality. Predictably, too, programming was largely LCD-driven and
labyrinthine, and construction quality aimed at something less than
heavy duty. They unashamedly represented the entry-level end of the
market, but then, if the trusty Casio was what you could afford, it
would certainly do the job.
Back in the present, I wondered if the PX3 would be
a case of history repeating itself. Typical street price is a mere
fraction of some of the stage piano competition, and yet the spec-sheet
and marketing blurb puts it very much in the big league. There's an
88-note hammer-action 'Ivory Touch' keyboard. The 250 editable onboard
sounds major on acoustic and electric pianos, with Acoustic Resonance
modelling, and a 'Linear Morphing' system that is supposed to do with
away with obvious sample-switching across the velocity range.
Other
sounds include plenty of mallet instruments, organs, strings, pads,
guitars and an entire General MIDI sound set. Keyboard splits and layers
can be set up to play internal sounds or trigger external MIDI modules
(via USB or conventional 5-pin MIDI sockets), and there are 64
'registration' memories for these kinds of setups. Effects include EQ,
reverb and chorus that can be shared amongst the internal parts, and two
multi-effects processors, which can be applied to specific individual
parts. A pitch-bend wheel lurks to the left of the keyboard, and there
are two assignable buttons for toggling effects and so on, as well as
rear panel inputs for two switch-type pedals. Oh, and the whole thing
weighs only 23.8lbs. With so much on offer, for so little, there's got
to be a catch, right?
Corpus Clavicordium
Probably the two main reasons for the PX3's light weight become obvious as soon as you start using it. The case is made entirely of plastic, and there's an external power adaptor.
The casework itself is sturdy, looks durable, and
doesn't flex or creak under any normal conditions. Rear-panel sockets
are not well supported, though. Only the USB and MIDI sockets are
anchored to the casework, so typical quarter-inch jack plugs plugged
into the 'L' and 'R' audio outputs can wobble up to about a centimetre
from side to side, presumably stressing the internal circuit-board
mountings. The power adaptor is a compact, in-line design whose 2.5m
lead is terminated by a two-pin IEC plug. It adapts to mains voltages
worldwide, and in use it barely got warm.
Now, what about this Ivory Touch keyboard? The hammer
action is on the weighty side, compared to some stage pianos, and the
key-tops are lightly textured — though no-one would mistake them for
ivory. The action itself has no obvious vices, and allows for expressive
playing. Superficially, it doesn't feel quite as silky or stable as
Yamaha's or Roland's best hammer-action keyboards, especially when
played very gently, but then it's difficult to be completely objective
about this. Subtle aspects of mechanical feedback through the key can
influence a player's (and reviewer's) perception, and in that respect
a big, heavy, metal-constructed stage piano can, by default, feel
classier than a plastic-bodied instrument. What I can be objective about
is that the Privia keys reliably and evenly generate the full range of
MIDI velocity values. And for the vast majority of pianists, especially
those playing jazz, pop or rock piano, the action on offer here won't
give a moment's concern.
Plugging In
Editing of the Privia PX3 is achieved via the button-heavy front panel and modest LCD screen.
When you switch on the PX3 with its unusual side-mounted power switch, it boots up ready for use in about 12 seconds, and defaults to its main piano sound. Selecting other sounds is nice and easy: there are eight labelled buttons for main instrument groups, and a pair of up/down buttons above for stepping through the variations within. A simple layer of two sounds or a keyboard split (or both) is just a button push away. The resulting additional keyboard 'zones' are configured using dedicated Zone Selector buttons, which also choose whether individual zones trigger internal sounds, transmit MIDI, or do both at once. It's all useful stuff, though it's worth noting that the PX3's strict adherence to the split/layer concept won't let you do more advanced stuff like creating overlapping zones, or even three or four adjacent zones spread across the pitch range. So far, so straightforward. Going further with the PX3 may well have you reaching for the User Guide, though — at least initially.
Sounds can be quite extensively edited within each
zone. You access groups of four parameters at a time, and shuttle
between them with the dedicated Parameter Selector buttons and repeated
pushes of the Zone Edit button. All the while, values are shown in the
LCD. There's plenty to fiddle with: part transposition, bend range,
volume and pan, EQ, effects assignment, filter cutoff, attack and
release, and vibrato. That's by no means an exhaustive list, either.
The ergonomics of editing, though, are hobbled by the
Parameter Selector buttons being placed to the left of the LCD, and not
underneath it, where they'd tally up with the parameters they select. It
seems like a minor point, but this and other little inconsistencies
contribute to the programming system often feeling cumbersome and
counter-intuitive, when in reality it's quite simple and fast to
navigate.
Global parameters, which are accessed in a different
way, using buttons to the right of the LCD, fare little better. They
appear in a kind of pop-up window on the LCD, through which you enter
a menu-driven system, but you might struggle to figure out that this is
what's happening the first time you try.
Of course, striking the right balance between ease of
use and programming depth is a problem that perhaps uniquely affects
stage pianos. We want them to be simple and immediate, but feel hard
done by when they don't offer workstation-levels of flexibility. The PX3
at least is programmable, and you can get quite creative with it.
Saving and recalling setups to and from the 64 Registration memories is
easy to understand, too. However, it's probably fair to say that while
most people will learn to navigate the editing system eventually, fewer
will learn to love it.
Rocking Out
Let's cut to the chase and consider the PX3's sounds. The two main acoustic piano sounds have a lot going for them. They differ in general character: one's quite middle-y and incisive, the other more luxurious. Here the Linear Morphing system does its job, because I couldn't hear any obvious velocity switching. Nor are there any terrible lurches of timbre between adjacent notes, and the extreme low and high pitch ranges are convincing. Some players may find the sound of very loud notes a bit forced and lacking that nice steely projection, and note decays are not exactly state of the art — after about two seconds, you're into that lifeless, short-sample-loop sound that differs so much from the beautiful complexity of a real piano's decay. But the PX3 is no worse in this respect than stage piano competition at three times its price. In my experience, when you rule out big computer-based piano sample libraries, only a very few keyboards (such as Nord's Piano 88) do significantly better. Anyway, regardless of relative cost, in the context of a typical stage performance or pop/rock mix, the PX3's pianos will do the job and sound really convincing.
Additional timbres include bright dance pianos, and
also compressed and mono varieties. They're all helped along by the
Acoustic Resonance feature, which simulates the additional depth and
breadth experienced when you depress the damper pedal on a real piano.
It's more obvious on some sounds than others, but as it's editable you
can easily decide how much of a contribution it should make. It's worth
noting here that Casio's Acoustic Resonance does not, apparently,
stretch to generating sympathetic string resonance between sustained
notes when you're not using the damper pedal. Still, only a select few
stage pianos pull off that stunt.
Amongst the main group of electric pianos, there are 11
distinct flavours of various Rhodes and Wurlitzer models, some clean
and others with ready-rolled phasers, tremolos and wahs, courtesy of the
on-board DSP effects. It's possible to discover obvious velocity
switching with all of them — the Linear Morphing technology doesn't seem
to be present here. Also, no amount of vigorous playing will tease out
the really barking, coarse tone that is such a useful part of a good
electric piano's expressive scope. But generally, there's lots to like,
and across all the sounds the immediate effect is impressive, both from
the player and the listener perspective.
The rest of the sound set is hit and miss. There are
some good organs and mallet instruments, but the string sounds have
a tendency to be rather harsh, and both the Yamaha DX sounds and
electric grand pianos are, sadly, very poor indeed.
Of the on-board effects, I have no complaints with the
shared Reverb and Chorus; all parts can make use of them simultaneously,
and they're quite respectable. Many of the 64 DSP insert effects are
good too. There are masses of chorus and phaser variations, and the
rotary speakers and autopans are great to have around. The distortion
isn't so nice, though, often setting your teeth on edge and emasculating
the sound you've applied it to, rather than beefing it up. The
LCD-driven programming system isn't altogether up-front about effects
assignments — you sometimes have to do a lot of digging around to see
which parts have which effects applied.
Turning now to some aspects of playing the PX3, having
a pitch-bend wheel on hand is a bonus, but a momentary button (the one
marked Assignable 1) is no replacement for a mod wheel. On the other
hand, the second assignable button is genuinely useful. It latches on
and off, and is ideal for toggling Leslie speaker rotation speed on the
organ sounds. The supplied damper pedal has a unexpectedly shallow range
of action, and I was forever accidentally damping held chords. There is
a second pedal input jack, switchable between soft (una corda) and
sostenuto functionality.
Conclusion
As I hope most of this review has already made clear, the PX3 isn't some poor-sounding, hugely compromised budget item and has some really strong points. It's not perfect, of course. There are too many duds in the sound set and effects department, and the programming system, with its multi-purpose, strangely located buttons, can drive you nuts until you're used to it. It's a shame there's no modulation wheel too.
Balancing these criticisms, though, are probably the
best acoustic and electric piano sounds that have ever been available at
this price point, and an 88-note hammer-action keyboard that wouldn't
be out of place on an instrument costing several times the PX3's asking
price. In short, Casio have got all the important things right.
Does it stand comparison with a Roland RD700 or Yamaha
CP5? Yes and no. Yes, in that for many typical performance situations
the PX3 will sound and feel every bit as good, and be miles easier to
get in and out of the venue! No, because for really heavy-duty use
a burly, metal-constructed stage piano or workstation is still the right
tool for the job, and may well have better non-piano sounds. It's not
really a fair question, though, as the PX3 is a quarter of the price of
these keyboards.
If you're after a stage piano and you're on a tight
budget, look no further. If you're in a position to spend more, you
should still audition the PX3, and consider what fun you might have with
the balance. .
