What frustrates me about the piano sounds on the i30 is that with all the ones that come from Korg, there is really only ONE acoustic grand piano, and it is very weak in my opinion. I think they could have done much better. When I contacted Korg at the release of the i30 and complained that I though the piano wasn't good enough, the New York people who work at Korg US agreed with me but said this was the final voicing that the European Engineers liked for that market, and although they could have put more pianos in the Rom banks, they chose not to. It is probably the biggest reason why many of my customers didn't buy the i30 over some of the other arranger keyboards. There are many very good other sounds, but the Piano left me wishing for another!
