Reference
You can play back audio data on a smart device or a
computer with this instrument. You can also record
your keyboard performance as audio data to a music
production app on a smart device or a computer.
When using this function on a computer running Win-
dows, you will need to install the Yamaha Steinberg
USB Driver to your computer. For details, refer to the
“Computer-related Operations” on page 8.
Audio Loop Back On/Off
You can set whether audio sound input from the [USB
TO HOST] terminal is returned to the computer/smart
device or not along with the performance played on
the instrument.
While holding down [METRONOME] and
[RHYTHM] simultaneously, press the G5 key (Off) or
G#5 (On).

Computer
• Before you transfer an SMF file from a computer, make
sure to transfer the User Song to a computer for safe
keeping, since already-recorded data will be replaced
with the new transfer.
• Certain MIDI files in SMF format 0 or 1 may contain data that is not sup-
ported by your digital piano. In such a case, the files may not play as origi-
nally intended.
Playback/Recording of Audio Data
(USB audio interface)
• If you are using a DAW (digital audio workstation) with this
instrument, set Audio Loop Back to Off. Otherwise, a loud
sound may occur, depending on the settings of the com-
puter or the application software.
• If this instrument somehow malfunctions or fails to operate properly, try initial-
izing the data as described above.
