Just got it this week. As many have said, this is a huge upgrade over predecessors. I’ve owned(and sold) the DGX 650, grandkids own a DGX 660 and now have the DGX 670.
This keyboard has style features that aren’t even in my Genos.
I’ve owned a few PSR’s, a Tyros, a Roland 2000(sold) and a Korg arranger. I still own my Genos.
It seems to me, that this DGX is the most bang for the $$$ keyboard I’ve ever purchased.
