Thanks, but maybe I wasn't clear enough. I want exactly the same as you, just change the octave in a channel(track) than save the style. I don't want to record a new track. I really can't see why this should be a problem, not even with the Audya. Glad I'm not the only one that can't figure out how to do this. I use style modeling very much, and I think it's great feature. After many years with Korg I know the Korg OS (PA 80-PA800)pretty good, and after playing the T4 for 3 days I feel I know that OS better than 2 years with the Audya.
