Dennis..,
I think Korg will address those things.., BUT at the moment at least IMO.., I would say this latest OS release is clearly to challenge the Tyros line (for the moment though).
Korg couldn't let Yamaha release their new top arranger without first giving them the finger

I would hope Korg IS working on an OS update to fix real issues for player too.
