Feature:
You get what you pay for. The keys are cheap and plastic-y, but if you just need to tap out a melody into your sequencer then they get the job done. The keys aren't weighted so you may need to adjust the note velocities after recording. The 8 knobs are good, and the octave-shifting buttons are nice and quick. I wish I had got a keyboard with another octave of keys though; 2 is restrictive sometimes.

Quality:
It seems more flimsy than it is; it's survived being dropped as well as more than a few rough airport luggage trips. All the same, it is plastic, so I wouldn't drop-kick it into a cement wall or do whatever drunk musicians do that makes physical quality so important.

Value:
When I bought it it was easily the most affordable option in its class, but that was a couple years ago so I don't know if any more worthy competitors have been introduced. I think price is its main selling point.

Desirability:
It's aesthetically appealing, but just doesn't look professional; it won't impress anyone except maybe your kids.

Sound:
N/A

Ease of Use:
Everything works as it should except the transport buttons which I can't get to work with any sequencers (but that might be the sequencer's fault, idk). Also be sure to use the latest drivers from M-Audio's site, I had issues with the earlier ones.

Support:
Haven't used it

Overall:
If you need a keyboard and you're on a budget then this is a good option. I wish I'd bought one with 3 octaves though. It was my first keyboard so I thought 2 octaves would be enough, especially considering that I do simple dance music. Still, 25 keys just feels restrictive a lot of the time.

Feature:
Pretty feature-packed for such a small keyboard. 8 knobs for midi controls, a data entry slider, and each key on the keyboard can be assigned as a midi controller at the push of a button -- then back to being a key again. In the back it has two midi outs for controlling computer gear and tone modules separately, and a USB interface as well. It also has THREE power options, 9v wall wart, 6 AA batteries or USB power from your computer. It is at its most useful as a midi controller, though, and less as a playable keyboard. Its very stiff plastic keys are not comfortable to play, the pitch bend and modulation wheel are in a strange place to save space, and the 21-key range is uncomfortably tiny.. even smaller than my old Moog Prodigy and Roland SH-101! But it does have a couple of lightning-fast response Octave Down/Up buttons. Still, just keep in mind that 21 keys is really small and buy it for the midi control features and you'll be happy.

Quality:
It's pretty solid. It's plastic, but make no mistake it's not a flimsy thin plastic. The rubber feet had fallen off mine during shipping, but they stuck right back on and haven't moved since. I've got no complaints about its ruggedness. The keys just respond pretty stiff.

Value:
I got mine as a bundle with the FM7 (no longer available). As a standalone, I think it's a little pricey for such a small keyboard. It's real value is as a midi controller, but you're paying for the additional feature of the keys.

Desirability:
Let's be honest, it looks like a toy. It looks out of place next to my other gear. My 4-year-old thinks it looks cool and can't understand that I didn't buy it for him. If it doesn't prove a bit more useful soon, I'll probably go ahead and give it to him for his own computer.

Sound:
Makes no sounds of its own, except a slightly plastic percussive sound when you hit it with something.

Overall:
Ah. I got it as a bundle for less than the software alone normally costs, so I can't complain one bit. But at the market price, I don't think I'd buy one, I'd have to go for something bigger and test it out first to see how the keys respond. But the bigger ones cost as much as used synths that still have dynamite sounds, like the Korg M1 and a lot of new, low-end Yamahas that still have midi in/out. So I can't really justify buying just a midi controller.

It's great as a portable keyboard. But it is difficult at times to lay down what I need to. It feels a bit cheap (both the keybed and the housing). The three digit LED display is not helpul (it would be better if it at least had a 24 character lcd screen). It more often than other controllers sends note-ons but no note-off leaving hanging notes. Don't get me wrong. I like it more than I dislike it. It is sleek and a perfect companion to my Quattro/Reason/Cubase SX laptop portable rig. It would be a much better product though if it had an extra octave and a better LCD screen. Other than that it is a nice piece. The knobs are helpul for Reason. The modulation and pitch wheel are a bit cheap feeling but at least smooth in feel and response. Perhaps a little too much resistance on the pitch bend wheel but is does it's job. A decent value.

Nice features in a controller; I've used it with the demo version of Reason, and it is really nice to have the 8 assignable knobs to play with. The pitch and mod wheels feel a little chintzy, and the springs in the pitch wheel are a bit stiff for my taste. I also find the action of the black keys a bit stiff, but I seem to hit them too near the hinges. It has many features I have not come near using, however.

If you're just getting started with a MIDI program like Reason, then this little baby makes the perfect, low-cost solution for a keyboard controller. It's easy to set up and it eliminates the need for a MIDI interface. I have set mine up on my Mac and my PC. The both work like a champ!

Feature:
The knobs and the slider are programable, wich is useful although the programming method is a little unconfortable.

Quality:
You know M-audio, they're not exactly the best out there. The keys feel cheap, but it makes its job. You have better options and quality with Evolution but Oxygen is the less expensive, so it

I would raccomend this small keyboard to anyone who is passionate with the power of the synths of any type, software or hardware. Althought it only has 25 keys, it has 8 knobs and a lot more functions imaginable for little keyboard like this. I just love it!

I have some soft synths like reason and rebirth and am looking for something to easily controol some of the features on it. For the price you can't beat it. Midiman is awesome.

Feature:
features are pretty good for only a 100 dollar keyboard

Quality:
quality is pretty good the keys need to be a little bit more precise but all u need is a 12 volt 1000ma power adapter and ur good to go because there's a slight lag when u hit the keys

Value:
a very good price

Desirability:
i have it

Sound:
sound quality is not that bad im using reason i probalby just need better samples

Ease of Use:
really easy to use no complications or tricks with this keyboard

Overall:
really good keyboard i just wish the keys felt like those 600 dollar synths out there

Feature:
knobs are not 360 ...so it's bit a hassle to turn them in zero position with "midi mute" before you use them to control any parameter... ...memory is reseting all your configurations every time you turn off this controller, beats me why ...very complicated to program
