M-Audio O2
It's got Knobs, faders, and keys. Not bad for a 25 key portable keyboard. However, M-Audio controllers with more keys and the same amount of knobs and faders cost less money. The keys are half-action, which means that the keys dont depress (go down) as much as a regular keyboard. This is really a hate it or love it thing. I like it cuz it let's you play the keyboard faster, but at the same time it doesn't have as great a range of velocity levels.

Price paid: $199.95


It's a midi keyboard controller. It's VERY easy to use.


It's quality is the best you can really get for that price. It feels a little cheap and plasticy, but it's not so bad that it takes away from playing it.

I like it. It's not necessarily the best midi controller, but it's M-Audio's best portable keyboard.

- What technical features/characteristics motivated your choice?
I wanted a small, possibly portable keyboard with a fair amount of assignable knobs & things. Oh, and i needed it to be cheap.
This one has those 'features'.

- What connection types are there (MIDI, pedals...)?...
Now i sold this so check before you buy...there is a USB connector, that's for sure, and i think there is also a MIDI out but i'm not sure anymore.

It's quite basic but, still, it has quite a lot of buttons & knobs to fiddle with.


- Is the action/feel of the keyboard nice? Does it suit your needs?
Need i say more? This keyboard is small, light & cheap, and that's exactly what the keys are: small & cheap.
Hard to talk of a 'feel' at this stage. I have very little experience with keyboards (i own a Yamaha PSR-90...which says a lot, doesn't it?...and a MicroKorg) but this is the worst i've ever touched.

- Is the general configuration/setup simple?
Using it is simple, very simple, but beware: no Windows 2000 drivers. You need XP. They probably have Vista drivers by now but that wasn't out when i had mine.

- Is the channel/patch selection simple?
Seemed simple enough, i didn't keep it long enough to really say, though...sorry.

- Is the manual clear and sufficient?...
Same as above.


In my experience, totally unusable. Absolute rubbish.
Yes, i mean it.

The action of the keys is about 2 mm (ok, i'm exagerating here, but you get my drift...).
You have to jump onto the keyboard with all your weight to get the velocity to his 127...and you can't set the velocity curves...aaarrrgh...!!!

The best thing about it was the knobs & buttons...i guess you could use those quite easily...but forget about the keyboard.

Overall? I feel sorry for the guy who bought this off me. Looking back, it's the sort of rubbish you'd probably throw out the window, break with an axe or burn just out of frustration if youo could afford to...

BUT....BUT....don't go & think all M-Audio products are this bad...!
After my terrible O2 experience, i bought the Axiom 49...a FANTASTIC MIDI keyboard...just brilliant throughout. Ok, it's twice the price and 10 times the weight...but WOW! You can actually USE it...think about that...

Simple enough


The touch is nice and not too hard I think it will soften a bit over time.

configuration c is plug and then detect any c

use is apparently not too complicated, although I have not found any functions.

The pitch bend is rotten but not normal c wheel not vary as a personal will, but that is enough.

the manual is on a sheet of paper, therefore, (


2 days.

I like the size of the unit. cot for the negative: the velocity to me that is over 3 floors. a low, medium and strong recognizable. can be only use it will get better

Report Q / P, I would say that 178 c a reasonable price to see a bit too much I make the product 150 if I could but then the keyboard and comes with a USB cord and Reason Express, already c not bad for the price

Touch is trsdsagrable, trs The keys have a short game, the coup is pert feel of a real keyboard and you lose patience APRS few minutes, there is a midi out, keys are ill attach the coup, they left must go! In addition I have my soil that does not work `APRS utillisation trslgre a year!

I will never do it again this election, the sudden I'm trsdus semla as this a good brand, the range is from netement down in my estimation and I am trsdu
