Reviews
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.
- Keyboard Magazine, July 2005
"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."
- Downbeat
"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."
- Sound on Sound, April 2006
“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.”
