Feature:
Would be nice if like the Evolution it had templates that lable nobs and sliders for common uses. so many knobs i get lost. I usually program a four or five to do common functions on several instruments. <img src="http://www.evolution-i.net/images/fp_top_ad_right_reason.jpg....imgtag" /> Another thing that would be cool, if the LED display could be configured so that if you dont want to see every midi message its sending. Maybe you just want it to hang out and relax. I would also like to change the colors of the back light on occasion. Im happy that it is back lit! dont get me wrong.

Quality:
I had to return one. Luckily it was in the first years warranty. The keys were sticking (only comming 1/2 way back up). And they have some springy noises in them. Its not built for the road, but I use it at the big gigs. Made a custom case for it. Lighter than my 90lbs controller, but 40lbs plus another 20 for case and accessroies, its a beast to move. But its 88 weighted keys.

Value:
I believe it is the cheapest 88 key controller with the most knobs and sliders. but you get what you pay for. they didnt put in any supperior craftsmanship here. but it does a fair job.

Desirability:
I saw one guy who did his own repairs on his. while he had it all in peices, he went ahead and put a sweet paint job on it. I think the silver trend is comming to an end or going going gone already.

Sound:
I read one reviewer saying that it has sound. Yeah mine also has alot of noise in the key action.

Ease of Use:
It took me a while to learn to use it. I am more hands on learner, but i kept the manual handy for the first several months.

Support:
Even though I was happy that they were so easy to get an exchange (fast too) but the new keyboard keys are still a little springy sounding. No sticky keys yet, but this one is still young.

Overall:
Ill definately play this thing into the dirt, but that might be sooner than Id like. but the trend of cheap keyboard controllers out there. I try not to get too attached to it. its just a piece of plastic, wires and whatever else.

Feature:
You will be hard pressed to find a controller with this many features in this price range. Tons of sliders and knobs. More parameters to tweak than most 88-key controllers.

Quality:
Looks mean, is absolutely HUGE and heavy. Blue backlight to screen and buttons. Key feel is good for this price range, but it is not a piano by any means, but again, look at features for cost here, and keys are weighted (but seem to bounce I agree). Does not look cheap at all.

Value:
The most functions in this price range, or even against a higher price range for that.

Desirability:
Looks like something you would not be embarrased with to use on stage.

Sound:
No sounds, controller only. Sounds depend on software.

Support:
Have not had any previous M-Audio gear, but their web-site appears easy to use.

Overall:
Just buy it. Forget something smaller with less functions for a bit less.

Feature:
Knobs, Sliders, Buttons, Keys - lots of all of them. What's not to like? 4 zones, USB interface, great value. Keyboard feel is so-so. Weighted, little mushy/heavy. Adjusting velocity curves helps a lot. Consider that you're getting the equivalent of a Mackie C4+ Keyboard in the bargain and its a great deal.

Quality:
Feels a bit on the cheap side - but for the price - you can't lose.

Value:
Really good value for the price I think.

Desirability:
Its pretty sexy with all those knobs, buttons, sliders, and keys.

Sound:
No sound - its a controller

Ease of Use:
The manual is weak. Software for programming it is so-so. It takes some digging to realize potential.

Support:
Once you reach them, they are good. But long hold times....

Overall:
Should do fine - use it in studio - might buy a second one for live because I hate tearing it out of my studio to go gig.

Feature:
There are lots of knobs, buttons, and even 88 weighted keys. I have to say the velocity and feel are not top notch. But for $300 (on sale), it's a hell of a deal. There's no aftertouch either so I give it an 8.

Quality:
It is big. Recommend keeping the packaging to move it around. Hasn't gotten any damage on it yet so I am happy with it.

Value:
I like it for piano playing (88 keys), but I wish I would have gotten a smaller one with after touch for synth playing. Looking back on it, the Line 6 kb37 would have been pretty cool. I am content with this one though.

Desirability:
no sexiness to it. Who cares?

Sound:
I rated a 3 on sound because it doesn't have any sound. Fine with me. It is a great midi controller.

Ease of Use:
If you don't know how to wire up a midi controller to a soft synth, it may take you a few days to get everything down (it's very easy if you are the slightest bit computer savvy) It is big so it is hard to put it near you computer. I have mine to the side of my computer right now and it works good for the price.

Support:
I gave a ten because I have never had to contact tech support.

Overall:
Probably will use this for the rest of my life unless I get a hardware synth, which I probably won't.

Feature:
feature overload.

Quality:
My only complaint is that the keys have a awkward bit of bounce to them -- when doing rapid drills, there is a point beyond which the keys can't keep up with your fingers.

Value:
Definitely worth the price. There was nothing anywhere near this price range that met my requirements.

Desirability:
This is a very pretty piece of gear.

Desirability:
sezy

Sound:
software dependent.

Support:
can't rate just get it

Overall:
Key ungrading from a cassio to studiologic pro 88 was a quatum leap for me. So this thing is a starship to me. Seeing how I paid less for it that the cassio a few year ago; I have to agree with the positive reviews. You get what you pay for. If I had wanted a panio I would go buy one. Comparing a keyboard controller to a panio that usually cost thousands it just plain stupid.

Feature:
Enough nobs and sliders no matter what your doing. Only 10 presets but if your more on the digital side of this product, you can save presets on your cpu and swap them out that way, the M-audio software helps alot as well.

Quality:
Everythings held up fine so far, its a heavy board, probably not a great gig board but I dont use mine for that.

Value:
For its rediculously cheap price, you get a very decent board. I got mine used and it works fine.

Desirability:
It looks very nice, actually looks more expensive than it is.

Sound:
No sound, its a controller

Ease of Use:
Plug the USB in and go, doesnt even need a power cable. People seem to be saying great action and bad action in all these reviews. What I would say is that if your an acoustic or grand piano player you'll like the key action or get accustomed to it much easier than a non-weighted board. Personally I cannot use non-weighted keys because they are far too light and I always hit keys I dont want to. Its not exactly like an acoustic piano but its close and the keys have a nice heavy feel. Those with classically trained fingers won't have a problem making these keys do what you want. If you are normally a synth player with non-weighted, or lightly/semi weighted keys, you will probably hate this board, these keys are much heavier than you will be used too and will feel "clunky". They are a bit noisy but nothing even semi-loud wont immediately drown out. Mine have held up to alot of Beethoven and Mozart so far and still no breaks or sticks.

Support:
Havent needed it yet

Overall:
So there are how many other weighted 88key MIDI controllers out there? 3? I wasnt going to waste money getting a keyboard with sounds that I would never use, so i saved a bunch of cash. I use Apples new Logic Pro 8 with this board and using Mainstage is all you really need to program this boards nobs sliders and splits. Its SO FREAKING EASY WITH THE RIGHT SOFTWARE!!! If your doing it through the synth then your not using this board for what its meant for, this is for people who use the computer vs the syth itself, not the other way around. Take all the money you would spend on an expensive synth and go spend it on a good cpu and software, this thing and a laptop will rock your socks off and make much better sounds than any board. Softsynth sounds are way ahead of on-board sounds in quality and variety and much easier to customize. My setup sits beside an acoustic piano I never use anymore because I have at least 12 different Piano sounds I can use that sound like $40,000 grand pianos.

Feature:
Just about every MIDI control possible

Quality:
The feel of the keyboard is not like a piano. The weighted keys bounce and it seems like the weight is bouncing back into place when playing the same note consecutively. Feels little strange since I'm used to my old piano, which had constant tension on the keys, not the bounce

Value:
Despite it's shortcomings, there is no other controller on the market at this price point that is quite like this. Sure there are better feeling keyboards, but they cost over $2000

Sound:
No sounds, this is strictly a MIDI controller

Support:
Everything is still working fine

Overall:
The feel of the keyboard is a little wack, but overall a great deal

Feature:
Not sure what the last user was grumbling about, this thing has 4 different zones, a number of different velocity curves, all the knobs, buttons and faders I'll ever need, and it feels like playing a real piano.

Quality:
This is a sturdy device. It is pretty heavy to lift, but I'm using mine in the studio as my main studio keyboard controller so I don't really have to carry it around. You could definitely take it on the road with you, but I'd recommend a helper. I mean, it doesn't weight any more than my Wurlitzer.

Value:
I use this thing all the time. It is a great price for what you get.

Desirability:
Its very sexy

Sound:
no sound

Support:
M-Audio has a great tech support department. I had a question on setting up the buttons to change presets, and they were very patient and helpful.

Overall:
I love this keyboard. Would get it again.

Feature:
As a MIDI controller....it was great but As a piano controller it not good enough

Quality:
TOP panel is good and solid but bottom panel of the keyboard was not made from metal sheet. (What the heck is this?) Fader is very good feel.... knob is just ok. I don't think this one is good for "on the road" application

Value:
very good price for all feature they gave us

Sound:
it is controller (no sound)

Support:
I deal with dealer they are very good

Overall:
I want to up grade very time I buy more gear. So....I'm not buy the same thing twice
