My Pro-1 is 16.5" and my Keystep is 19" exactly - so it’s just a perspective trick where the Pro-1 is shown probably quite a bit higher than it appears at first glance
The Swing appears to be a bit wider - it won’t harm them to make the chassis beefier because my KS sags quite noticeably, it’s also (they all may do) got a very patchy aftertouch consistency across the keys, so not cloning that could be a win
It’s a strange clone indeed, making it with 37 keys may have been a sufficient differentiator, but it’s just not cheaper enough to sway people imho - it’s the upcoming market I guess they’re aiming for, folk just starting on their journey
This is very far from the most brazen clone, but it could be the most bizarre
Arturia in white/grey is classier and has a classier name - but folk now have an additional slightly cheaper choice
