There doesn't seem to be much major wrong. I'm sure they'll fix it quickly. They normally do. A couple of Korg guys monitor the forum over there and are quick to respond.
How many bugs where there in Yamahas and rolands latest released instruments?
Overall despite claiming to be a professional company, Korg Italy and Ketron never proofed to be able to release the same reliabillity as Yamaha and Roland... Its just a fact...
