I think I found the answer,....
Changing the split point If you are not comfortable with the selected split point, you may set the split point to a different key.1Touch the Split tab to see the Split Point panel.
2.Touch the keyboard in the display, then play the lowest note of the Upper section onthe keyboard.
3. As an alternative, touch the Split Point parameter to select it, and use the VALUE dial to select the new split point.When you change the split point, the "Global" parameter is automatically unchecked. This is because you are setting a "local" or "temporary" split point, and not the "global" one, used across the whole instrument.To change the
"global" split point, go to the Global > Mode Preferences > Style page, and set the"Split Point" parameter.
