I had previously owned the O2, also from M-Audio, and so what i really wanted here was a keyboard that worked...with no latency...with velocity curves you can choose...and keys that actually had some sort of touch to them.
Well, the Axiom has all that and more, although i'm not sure the 25 model has the adjustable velocity...check before buying cos that is one hell of a feature.
- What connection types are there (MIDI, pedals...)?...
USB, MIDI out, MIDI In, Expression jack, Sustain jack, power in, on-off switch, all on rear.
After my disastrous experience with the O2, i wanted to check this one out thoroughly and went round stores asking a lot of questions...and demanded to try it.
I tried some other keyboards in the process, of course, some of which were top of the range very expensive synths...none were as good as this except this with a proper heavy piano touch. But you can't compare them, really: this was the best of all the semi-weighted ones.
Haven't used it extensively yet but everything seems simple.
The endless rotary knobs are a plus. You even have pads! Loads of buttons all over the place...you also have faders! The array of assignable switches is virtually perfect.
I got this second hand for 160 €...instead of 250 € new. So the value is amazing (for me) . I haven't used it much yet but it's a pleasure every time i do.
The only thing that could make it better? More keys (get the 61 model then!) and a proper weighted touch.
Is this the best MIDI keyboard of this size/price? Most probably, yes! Would definitely buy it again!
