Procedure
To load a scale preset, select it from the pop-up menu to the right of the Scale button.
The pop-up menu lists factory scale presets and user scale presets. Factory and user scale presets are separated by a line.
Note
To deactivate the selected preset, click the On/Off button to the left of the pop-up menu. When turned off, no tuning scale is applied and the piano sounds with its originally recorded stretched tuning.
