The disk in the disk drive has not been
formatted, or has been formatted for a
device other than the MDF3. Check the
disk, and format it if necessary.
The MDF3 is unable to read or write data
using the disk in the disk drive. The disk
is either unformatted, or has been format-
ted by a device other than the MDF3 (or
MDF2).
If this message appears after you have
formatted a disk, the disk is probably bad.
Replace it with a new one.
You have selected a file written using a
data format other than those which the
MDF3 is capable of reading.
Select another file. The MDF3 can only
read standard MIDI files (format 0/1),
ESEQ format sequence data files, and
MDR data files created by the QX3 in
MDR mode.
A function cannot be executed because
the displayed file cannot be found on the
current disk. You have probably changed
the disk after selecting a file but before
executing the function.
Insert the disk containing the displayed
file and execute the function again.
MIDI-related errors:
There is something wrong with the MIDI
data being received. Check the transmit-
ting MIDI device and the MIDI cable.
The amount of MIDI data received at one
time has exceeded the MDF3’s process-
ing capacity. Decrease the amount of
data being transmitted to the MDF3.
Other errors:
The batteries are running low. The MDF3
is not capable of functioning any longer.
If you attempt to use the MDF3 after this
message appears, the unit will not oper-
ate, or the message will appear again af-
ter a few seconds.
Connect the AC adapter or replace the
batteries with a new set.
Note:
If the “YAMAHA MDF3” initial display
appears when you start a playback or record-
ing operation, it means the battery power is
so low that the MDF3 cannot display the “Bat-
tery Low” error message. Connect the AC
adapter or replace the batteries quickly.
A disk has been removed from the disk
drive during playback or recording.
Never eject a disk during playback
or recording, as doing so can dam-
age the disk or the disk drive.
