[Auto Resume] is set to <Enable>.

Solution:

Turn [Auto Resume] to <Disable> then turn the power off and back on again. For more information, see “Saving the Digital Piano Settings (Auto Resume)”.

Solution:

• Check that the Digital Piano is properly connected to the computer with a USB cable, or that the correct is selected in the settings of the computer’s music software.

• Turn off the power to this Digital Piano and close the music software on your computer, then turn on the power to this Digital Piano and restart the music software on your computer.

Cause:

This is a boundary between sound ranges caused by electronic processing called digital sampling and is not a malfunction.

• This process records the original sound of the instrument in multiple ranges, including low, mid, and high ranges, and creates a single tone in order to reproduce the sound quality of each range of the original instrument.

Cause:

When using Layer, Duet, playing a Built-in Song, or using the recording function, multiple parts sound simultaneously. If you press buttons in such a case, the tone-specific internal effect settings will be automatically changed, and depending on the part, this phenomenon may occur, but it is not a malfunction.

Solution:

Deletion of User Songs can be executed from a smart device connected to the Digital Piano. For details, see the instruction manual for the dedicated app.
