Feature:
It have just what I need, and even more. The X-Y feature using the touch screen isn´t only cool, but very useful when performing live. The pads are very useful too, since you can assign midi CC events to them. They can also make the recording of a drum performance easier. The sequencer is very complete, and the last OS version includes a piano roll view to it. The only think that I lack on the M3 is the audio track feature. You can sample audio on the sequencer and play it with your entire composition, but it is not a real audio track. Anyway, I use my DAW for it, I´m just being picky.

Quality:
This keayboard is almost new, but I haven´t heard before about a Korg having quality issues. The faders feel a little bit weak but I don´t think they will have problems under normal use. The module itself is hard as a tank and very heavy. I have no complains at the moment.

Value:
Honestly I think this is the keyboard that can give you more for it´s value than anyone in this price range.

Desirability:
What called my attention at the begining was the touch screen. Of course this is not the only thing you would want on a workstation, but the idea of interacting directly with the screen instead of using buttons and switches (as the Motif) was so cool. The look is elegant and discrete, but it really looks like a piece of high technology. It is the center of attention at every place I bring it to.

Sound:
The sounds are perfect. I spend hours playing different tunes with almost every sound included. I have read some reviews comparing the M3 with the Motif XS or the Fantom G. I liked more the M3 since I it met my needs. I think the synth sounds that come out of the box are better compared to the other two. The electric guitar leads are good, but the power chord sounds could be a lot better. Of course this is a matter of taste and the style of music that you will perform with it. I love the electric pianos, the synths and the string section. The EXB-Radias option is a must. It can add 128 sounds using virtual analog synthesis. I only wish they could be more of them, but you can create and save your own programs on the M3 banks. If you have the opportunity to buy it, do it without hesitation!

Ease of Use:
The user interface is simply perfect. It is very intuitive and the touch screen makes it even better and easy to use. Every option seems to be in the place it have to be, and all the faders, switches, etc can help you to do your job. You can also use pedal switches and expression pedals to add more versatility to your live performance.

Support:
I own this product since June 2008. I haven´t call them until now.

Overall:
I´m very satisfied and pleased with my keyboard. Higly recommended. No doubt why it earn the
