Feature:
The best features are the full size touch screen & the diagonally angled top half of the keyboard..as well as the most intuitive & advanced sequencer I have ever had the pleasure of working with..much better than my Extreme's sequencer! The performance controls are incredible,but the keybed action is a bit too light,but the keys are spring-loaded,so it's pretty good-just not great-especially if you're accustomed to 88-key weighted action.

Quality:
For a keyboard that only weighs in at 15 lbs,it's a fairly sturdy board,but because it is made of all plastic,I would recommend a flight case for gigging. The only thing I am a little concerned with,is that this particular board is made in China,as supposed to Japan,so hopefully there was good quality control in the manufacturing plant there.

Value:
This is by far,the best value in a workstation on the market,as nothing comes close to this keyboard...in fact,it would be ridiculous to buy anything else for just over a grand.

Desirability:
It's a beautiful board with beautiful sounds & with beautiful functionality.

Sound:
The sound is excessively amazing...clean,pristine,impeccably authentic & soooo inspiring!!:~} The strings,synth leads & pads are shockingly good...and the guitars-particularly some of the electric guitars & acoustic guitars are better then my Triton Extreme..really! The drums are jaw-droppingly stunning....the pianos are not quite so authentic,but very respectable for a workstation of this price.

Ease of Use:
Superb,out-of-the-box sounds & tremendous sound tweaking options...for such a complex workstation,it's realtively easy to navigate through-especially if you have prior Korg experience,but because of it's advanced features,it could be a bit of a learning curve,if you are not familiar with the M3's functions. As for the manual-could'nt tell you anything,as I did not need to read it.

Overall:
I will be buried with this keyboard,as it's my soul mate...I considered the Kurzweil PC3,but this board gives me what I need for half the money.

Feature:
lets be reasonable and not compare this to the m3 or the mr..its a great synth in this price range, theres something very unique about it and dont expect better for 1200..its a bang for buck without question..the touch screan, the m3 sounds, dual arps and more, if ur looking for a synth in this price range, i really cant understand why anyone would second guess this..its a GREAT machine!!!

Quality:
I got scared reading a few reviews on the m50 having a plasicy feel and crappy keybed...COMPARED TO WHAT??? the roland v synth gt..????(which is 3 times as much and doesnt feel a heck of alot better imo) again, lets be reasonable, the keybed is just fine, feels great to me, the m50 is light yet solid and confident, you get what you pay for people, its a korg, you cant and wont go wrong..its just fine!! they cut corners but again, in this price range its a great investment..a very cool synth.

Value:
worth it!

Sound:
The sound of this synth is beautiful! The quality of sound is pristine, rich and very professional. The sound for the most part is expressive. Iv checked out most of the sounds and i have no complaints ..(ok just one or 2...the finger bass sounds could be better and more punchy and boomy and less "perfect" in regards to intonation..and as i found myself adjusting the sound with the 4 knobs, that didnt even help much..but hey, you might like it. And the pianos are fine but the grand isnt as grand as they made it seem it would be..IMO ...The presets are just fine and the 4 knobs to make your own sound are real cool and can really bring a sound to life. I'll use this as my work horse for studio production...itl really do the job and inspire so much creativity and make me look good. some awesome sounds in this thing. I think i'll be really happy with it.

Ease of Use:
well im not a pro at this yet and havent had it long enough to be able to discern the ease of use but so far im making great sound from this and using alot of what it has to offer and i havent even read the manual..i believe its not gna be so difficult given the convenience of the touch scean and is very intuitive and just looks very friendly..im not intimidated by this synth, we have bonded and are geting along famously thus far :)

Support:
no poninion..based on what iv read, im in good hands.
