The i30 has fill to any variation and many other features that can be controlled by a 5 pedal foot controller.

I like just pushing a number or two to change styles all set up as I set them. I mostly use piano, bass, drums and jazz guitar.

The sax sounds on solo I don't use. However the big band stuff from the factory with saxes, trumpets, trombones and such sound pretty good to me.

I play sax so I don't care much for any of the sax sounds on most any keyboard for soloing.
