I have received mine. Having only been in possession for an hour, I don’t have a great deal to say about it, yet, except:
It’s immediately very impressive—plug in and go, everything sounds great
It’s rather easier to play than I expected, at least to noodle around on if you’re already familiar with the piano (I have zero prior Haken experience, and only a brief dalliance with Roli)
I’m curious to see how long it takes before I really absorb the finger spacing: the difference between “getting along”, and it all just feeling natural and automatic.
