Rikki,

You can pretty much do the same things with Yamaha's Style Creator. However, I haven't worked with the Korg for several years, so things may have changed a bit. I'm to the point now where I rarely have to tune or create styles. There are so many great styles available to work with that it only takes some minor tweaking and maybe a change in the OTS settings and the styles are ready for onstage use.

Cheers,

Gary
