Just wanted to add to the positive thread!
Got mine on Friday and have not been able to take my hands off it so far.
Firstly the sound quality is absolutely fantastic! A huge step up from the EMX-1
I was worried that I was going to feel limited by the few available parameters available, but Korg have been very savvy in setting up the selection of available oscillators in such a way that most routing options (sync, ring mod, octave, etc) are taken care of. Most of your standard sounds can be made from the preset routing options. Would like to see a few more in a future update (specifically some with NOISE waves) but this can currently be worked around by using a noise wave on another channel as there are 16 to play with. It's not a deal breaker by any means. It's also set out in a way that it is just as quick to manipulate sounds as the EMX-1. I feared a lot of menu diving etc, but I was pleasantly surprised at how quick it is to get tweaking!
Having more control over the drum sounds (most of which are already pretty great) is also a huge improvement. You can easily make your own huge sounding kick drums with a synth waveform of your choice, pitch envelope, cutoff filter etc. That's even before you get to the insert effects, my favorite being 'punch' which adds a nice analog style 'snap/thump' to the beginning of any sound you put it on. Other favs are the low EQ (for kicks) and bit crusher (for pretty much anything). Yum!
Sequencer is what it is. I would have preferred they stuck with the old style, but again it is not a deal breaker - it's just another way of inputting the notes.
I haven't checked my OS version yet, but I'm not hearing the gap as much as I was in the early demo's. I also noticed that if you change patterns via the 'pattern set' that there is no gap at all? Maybe my imagination though.
I bought this fully expecting to return it after Xmas and stick with my EMX-1. My plan is now to sell on the EMX-1. On raw sound quality and tone alone, the EMX-2 has the EMX-1 beat. There is also a noticeably 'wider' sound to the EMX-2 - the narrow sound of the EMX-1 always being a niggle for me.
If you are wondering whether to get one, I say go for it. If you buy it online, you can always just return it. I think it's a keeper though.
Thanks Korg!
