I got one of these yesterday and have spent about 12 hours with it so far.
I REALLY like it!
It sounds superb, and right up my street in terms of 'typical' timbres it creates. It's actually hard to make it sound bad. It's also incredibly quick to do things that would often be tedious or impossible to do with other synths. (Such as multi focus so you can control all layers at once for example)
I'm pretty new to synthesis so this kind of synth is great for me, as I often get a bit overwhelmed with so many options on my other synths.
I was a bit unsure about not having a screen but in practice i've found the LED screen along with the Nord Sound Manager to do everything I need, and actually I prefer having software to manage patches rather than enter text etc via the hardware, especially as patches loaded on the hardware from the software which I didn't expect.
The morph and mutate sound functions are great, and unison, layering and the good FX just make it so lush.
