There are three EASY PLAY buttons to the right of the display.

If you call up PIANO. it will call up the piano sound, set the keyboard mode to whole keyboard, and engage the Pianostyle chord recgnition (which needs at least three notes to change a chord, so you can still play runs without it going crazy.

If you call up ARR, it will split the keyboard, engage the left side to track the chords, and engage Intell mode (which is a cross between One Finger and Full chord modes, either will work)

After choosing the mode, you can then call up styles from the style section and the modes won't change. Two taps on the Style Part button (to the right of the sliders) brings up a mixer page where the style's sounds have icons at the top to tell you which part is which. A tap on these icons immediately mutes the Part.

Selecting sounds is easy, just hit the button for the Keyboard Part you want to change, the little green light above the main Part button lights up (all on the lower right side, labeled Keyboard Part), then just select the tones from the tone groups. There are a LOT, and some of the better ones are a few pages in, so try as many as you can...

It really IS the easiest to operate OS I have ever seen. Most everything does exactly what you would think it does...

Give the OTS's a try, while you are playing.... but they will ALWAYS split the keyboard and select INTEL mode as default - there is software to change all this if you decide you need the OTS's (stored with the style) a different way.

Hope this helps...
