Clearly there are gigging keyboardists on the design team...The complement of gozintas (sustain and soft pedal as well as expression pedal ins) and gozoutas (USB and MIDI) is best-in-class, and the front panel features are impressive for the money too. I’ve never met a sub-$1000 stage piano with all these features, let alone one that sounded so good.

"With a suggested retail price of $749.95, the ProKeys 88 is a great value for players, composers and educators who want to incorporate more technologically advanced samples and intuitive MIDI control into their keybaord performances."

"I found myself playing the Prokeys 88 for hours and coming up with great Split/Layer combinations when I should have been writing this review." - "I would have nothing but praise for this product even if M-Audio had delivered it at a few hundred dollars more, but the fact that they have brought it in at well under one thousand dollars is really extraordinary."

“I worked with our front-of-house engineer to find a sound that would sit well in the mix for the size venues we would be playing on this tour. I use the Grand Piano 1 sound (on the ProKeys88), which sounds great in the two octaves above middle C, where I spend plenty of time in the typical Train set.”

Our goal in designing the ProKeys 88 was to create an extremely musical and realistic piano experience. The caliber of a digital piano is greatly influenced by the quality and the size of the samples, so we started by giving the ProKeys 88 a generous amount of memory. Then, rather than dividing it up amongst a bunch of sounds you're not likely to use, we focused on the 14 sounds that are the bread and butter for many keyboardists—paying special attention to the stereo grand piano.
The ProKeys 88 delivers all the staple keyboard sounds needed by many musicians. Its flagship stereo grand is supplemented by an alternate grand designed to really cut through in popular music. The ProKeys 88 has electric pianos covered too. And the Clavinet brings one word to mind: “funky.” Acoustic and electric basses give you the option of layering a ride cymbal for jazz tunes. Vibes, ensemble strings and an inspiring warm, lush synth pad round out a great sonic palette for the gigging keyboardist.
The ProKeys 88 keyboard also features split and layer capabilities. Put a bass in your left hand and keys in your right. Chord with an organ while playing a piano lead. Layer lush strings over a piano. You can even have a split and layer simultaneously for a total of three sounds at once.
When it comes to communicating with the outside world, most digital stage pianos offer little more than a MIDI jack. In sharp contrast, the ProKeys 88 inherits much from M-Audio’s years of experience pioneering mobile MIDI controllers. It incorporates a full USB MIDI interface that communicates with your PC or Mac via a single, simple USB connection—perfect for recording with virtually all MIDI sequencer software on the market. (The instrument features class compliancy with Windows XP and Mac OS X without installation of additional drivers.) You can even control your sequencer remotely via front-panel Start, Stop and Tempo buttons.
There’s no need to mess around with additional gear to add basic effects to your ProKeys 88. On-board EQ lets you easily tweak the tone on the fly. You also get three different built-in reverb spaces that simulate different acoustic environments. Chorus fattens up sounds like the electric pianos and basses. And what’s a vintage Wurlitzer electric piano without tremolo? Experiment with different effects on the ProKeys 88 to create signature sounds of your own.
Every digital piano has a sustain pedal jack. But what about the sostenuto pedal (the middle pedal on an acoustic piano)? ProKeys 88 has it. There’s also an expression pedal for foot-control of volume. And all three of these pedals serve as MIDI controllers for outboard gear as well.
Ever need to practice privately? ProKeys 88 includes a 1/4” stereo headphone jack so you can play without anyone else hearing you—at home or at a sound check. Of course, it wouldn’t be an M-Audio product without high-fidelity 1/4” unbalanced audio output with specs like 20Hz-20kHz frequency response and 108dB dynamic range.
