Having read a lot about this product (some good reviews, some bad) i decided to fork out £339 and buy it.

Turns out it was a good decision.

Having spent 10 minutes trying to get the thing out the box, I plugged it in, connected midi and I was away. Straight away, I noticed the keys played great, and the piano sound was pretty decent.

The pedal supplied is great, and the sounds and features are fantastic (I especially like the ride cymbal layer). However it is rather heavy which could be a negative as I will use this for gigging, and the piano sound does sound a bit odd in the octave above middle C when using it on full volume. You get used to it though.

All in all though, a great purchase, and I'm sure I will use it for years to come!

Overall VERY pleased with this product

Was bought in mind for use as a substitute practise piano, also with scope for recording though Sibelius and Cubase etc. and use with my band. It was between the Prokeys 88 and The Yamaha P-60, both met my requirements (and i had played on the P-60) but i think i made the right decision.

GOOD Points...
- It has proved Extremely versatile as both a stage piano and a Midi input.
- very affordable (more so than the P-60)
- Good sound quality, the 'warm pad' and 'strings' are particularly good
- Lots of additional bits and bobs that have proved useful! (Equaliser, pitch bend, split + layed volume etc. etc.)

NOT SO GOOD Points...
- As far as stage pianos go, this is very heavy one
- No internal speakers (just for ease of use), which meant i ended up chasing after active monitors...
- Probably if your going for sheer sound and playing quality the P-60 has the edge, but there not much to pick between them (and the prokeys has alot more features)
- I have heard some things that would lead me to question its reliability. But mine working great! *fingers crossed*

All in all a very good piece of kit, very good price, and a very pleased customer =D !! Have already recommended to a friend and wouldnt hesitate to recommend it to anyone

I have had this piano for 2 months now. I need a "real piano" feel for my keys as well as a real piano sound. I know there are many famous brands out there offering a lot of quality stages pianos, BUT if you set aside your subjectivity and not look at the M-audio name on it, as they do not have a tradition at all in making stage pianos, you'll be able to bring yourself to a place of objectivity.
I highly recommend trying to play the M-Audio ProKeys 88 before you get an opinion. That's what I did and I loved its sound right from the start.

As a piano player and a lead vocalist in my band, as well as for my home-studio, I need something that was both a good stage piano and a MIDI controller in one, and I truly believe M-audio has successfully achieved that.

The feel of the keys is what you'd expect from a real 88 hammer action keyboard, also due to its 3 velocity curve function.

The sounds are good and very "tight" due to the large memory used for the samples and the detail and dynamics are very expressive.

As a MIDI controller you have enough for both studio and stage situations, the USB MIDI connection being a plus for those who do not have a standard MIDI port on your computer audio interface.

All in all, if you look at all the features, sound quality and practical aspects this piano/MIDI controller gives you, you'll find that right now M-Audio ProKeys 88 offers the best price-quality and price-features balance you find out there.

I'm happy with it and I'd buy it again.

Good quality onboard sounds and nice weighted keyboard action, both just as good if not better than the korg sp200, but with added advantage of all the midi controller stuff as well. Well built and not filmsy in any way. after spending about four hours researching midi controllers from £150 upwards I settled on a stage piano. My local shop had all 5 possibles on my list in stock and the m-audio is as well built or better as any other so I am very happy with it and price I paid.
