88 graded hammer-action keys

stunning 3-layer stereo grand piano

large 64MB sound bank with 14 world-class instruments

built-in MIDI controller functionality

best digital stage piano value on the market

The ProKeys 88 is the premium digital stage piano that doubles as a great MIDI controller. It's loaded with large, realistic samples—14 world-class instruments in all, including split/layer capabilities. We paired those great sounds with an 88-key graded hammer-action keyboard, delivering a realistic feel to satisfy the most demanding pro. The ProKeys 88 is also a great master controller keyboard, including a built-in USB MIDI interface for easy direct connection to your PC or Mac, MIDI In and Out jacks to communicate with other MIDI gear, pitch and modulation wheels, sequencer controls and more. ProKeys 88 pulls out all the stops in creating the ultimate playing experience in an affordable digital stage piano.

Ultra-Realistic Piano

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.

More Than a Stage 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.

88-Key Graded Hammer Action

Of course, a realistic digital stage piano must have a full 88 keys that are properly weighted. The ProKeys 88's full-range clavier features a graded hammer action that feels just like the real thing. It features three velocity curves tailored to different touches, as well as a fixed velocity for synth work.

Splits and Layers

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.

Control Your DAW

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.

MIDI In and Out jacks allow full communication with all standard MIDI gear as well. The ProKeys 88 also features performance controls that are rare on digital stage pianos, including pitch wheel, modulation wheel, two footswitch inputs, and expression pedal input. The three different ranges available via the ProKeys 88's combined split and layer functions can each transmit on a separate MIDI channel as well. You also get dedicated front-panel buttons for program change, channel, bank MSB, bank LSB and local on/off.

Built-in Effects

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.

Full Pedal Complement

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.

Headphones and Pro Audio Outputs

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.
