Control lock Meaning
Lower When this lock is closed, the Lower Sound remains unchanged when
a different Keyboard Set or Style is selected.
This is useful if, for example, you prefer to only play chords with the
left hand, while leaving the Sound in mute.
Hint: If you want the same Lower settings to be used during all
your shows, save your preferred Lower settings to the MY SETTING
Keyboard Set (automatically selected on startup).
Keyboard Mode (Split/
Full)
When this lock is closed, the status of the SPLIT button (therefore of
the keyboard mode) remains unchanged when a different Keyboard
Set is selected.
This is useful if, for example, you prefer to always play in Full
Keyboard mode, with chords recognized on the full keyboard range.
Hint: If you want the same Lower settings to be used during all
your shows, save your preferred Lower settings to the MY SETTING
Keyboard Set (automatically selected on startup).
Slider Mode When locked, selecting a Keyboard Set or SongBook Entry will not
change the status of the SLIDER MODE indicator.
