As far as details are published, it doesn‘t seem to have a user multi(!)sample option. I rely on that very much with my Kronos, since I cannot bring every synth I own to the gig. I also think 4x128 „scenes“ is not very much space for saving songs/setups/... and I didn‘t see a setlist function so far. The demos sound very good.
It seems to be even heavier than a Kronos 88, which is also not what I want to have.
At the moment it doesn‘t seem to be the Kronos killer I‘m waiting for, but at least it seems to be almost there. Perhaps the missing features (for me) were not mentioned so far.
