I stand to be corrected but I believe that on the Korg i30 you can overwrite banks C and D with your own styles, then transfer them to overwrite banks A and B thereby freeing up C and D banks again to load up again with even more fresh styles. So you end up with your own styles in all four banks, A, B, C and D.

Yes, John Tesh is a more than competent musician but, due in part I suppose to his previous TV persona, he comes across as just a bit too smooth and "plastic" for many people.

By the way, the girl who supplies the backing for the zany antics of Drew Carey, etc. on "Whose Line Is It Anyway?" appears to have a Korg i30 sat atop her piano, if I'm not mistaken.
