Troubleshooting
If you are having difficulty operating your Disklavier, see
if any of the symptoms listed below apply to your
problem and follow the recommended remedy.
The Disklavier does not turned on.
Make sure that the Power Supply unit is securely
connected to an AC wall outlet with the supplied power
cord. ( pg. 14)
Make sure that the Mains switches on both the Power
Supply unit and the I/O Center are turned on.
When the does not light green and stays
flashing green several minutes after the I/O Center is
turned on, turn the Power Supply unit off, wait
approximately 10 seconds or more, and then turn the
unit back on. ( pg. 4 “Turning the Disklavier On” in
“Quick Guide”)
No sound is heard from the supplied
Monitor speakers.
Make sure the Monitor speakers’ AC power cables are
connected to the SWITCHED AC outlets on the Power
Supply unit.
Make sure that the POWER switches on both Monitor
speakers are turned on.
Make sure the Monitor speakers are connected to the
OUTPUT jacks on the I/O Center with the supplied
speaker cords. ( pg. 13)
Make sure that the overall volume is adequately turned
up on the Pocket Controller. ( pg. 12 “Adjusting the
Overall Volume” in “Quick Guide”)
Make sure that the volume adjusted in [Balance] screen
is adequately turned up on the Pocket Controller. (
pg. 25 “Adjusting the Volume Balance among the
Keyboard Playing, Ensemble Sound, Software
Playback, and Microphone’s Input”)
In Quiet mode, no sound is heard other than the solo
piano sound during playback of a PianoSoft Solo song.
The Monitor speakers are not supplied with the
Disklavier PRO Series. In such a case, prepare active
speakers equivalent to the Monitor speakers supplied
with the Mark IV Series. ( pg. 105 “Specifications”)
The Disklavier cannot be controlled on the
Pocket Controller.
The Pocket Controller is beyond the maximum
operating range (approx. 20 m (65.6 ft.)). In such a
case, move closer to the Disklavier.
Make sure that the CF wireless LAN card is securely
inserted into the Pocket Controller’s CF card slot.
When you reinsert the card, be sure to reboot the
Pocket Controller. ( pg. 17)
The Disklavier does not read a song file.
The maximum number of the readable files in an album
(folder) is 999.
Make sure that the name of the SMF song has an
extension as “.MID”/“.mid” and the E-SEQ song has
“.FIL”/“.fil”.
The playback order differs from the order
on another device.
The playback order depends on the recording software
or other factors. Naming the file starting from numbers
such as 01, 02, etc. may solve the problem.
