Double-click “PIANO”.
• “PIANO” contains folders named MUSICLIB and 
RECORDER. Use MUSICLIB to load a song into the 
piano’s user song memory (Music Library 61), and 
RECORDER to transfer Recorder memory data to and 
from your computer.
* Before starting a store or load operation, first check 
the file name and extension to ensure it matches the 
ones shown in this column.
The initial default configuration for Windows XP,  
Windows Vista, and Windows 7 is to hide file name 
extensions. Perform one of the following operations on 
your computer to show file name extensions.
■ To show file name extensions under 
Windows XP
■ To show file name extensions under 
Windows Vista or Windows 7
■ To load a song into user song memory 
(Music Library 61)
• If there are two files with the names BIDSNG01.MID 
and BIDSNG01.CM2 in the MUSICLIB folder, only 
the BIDSNG01.MID data will be loaded into user 
song memory. If you want the BIDSNG01.CM2 file 
to be loaded in this case, change the name of the 
BIDSNG01.MID to something else.
NOTE
• The message “Cannot rename MIDIDATA” will 
appear on your computer screen if you try to change 
the name of the copied file to BIDSNG01.MID while 
there is already a file in the MUSICLIB folder named 
BIDSNG01.MID. Change the name of the current 
BIDSNG01.MID to something else and then rename 
the copied file to BIDSNG01.MID.
■ To transfer Recorder memory data between 
the digital piano and your computer
To transfer the digital piano’s current Recorder memory 
data to your computer, copy the contents of the 
RECORDER folder to your computer.
To return Recorder data you previously saved to your 
computer back to Recorder memory, copy it back to the 
RECORDER folder (and replace the current 
RECORDER folder contents).
