I wonder till what year (or century) we have to wait till Korg and others will include arpeggiator??? I know Casio did a few years ago but I'd prefer to have it in Tyros or PA or Genesys. They shouldn't call anything "pro" without this important feature. I think this is one of the features that keeps pro musicians from buying arrangers. Stupid for companies not to innclude it and I'm pissed!
